Creating dynamic, balanced student groups is an essential part of classroom management. Whether you’re grouping students for projects, discussions, or activities, organizing them efficiently can take up valuable teaching time. The Classroom Groups Manager automates this process, providing you with an easy way to create groups, assign seats, and avoid problematic pairings. With just a few clicks, you can manage class groups based on your needs while saving past groupings for future reference.
Students in MYP Design class grouped for a 2-week Design Challenge
This tool leverages Google Apps Script to turn Google Slides into a versatile group creator and random student selector. It’s designed with teachers in mind and offers several features that make classroom management more streamlined and engaging.
1. Create Random Student Groups of Any Size
Teachers can generate random pairs, groups of 3, 4, or 5 students, or even custom groups centered around selected students. Whether forming small teams for a project or organizing students for discussion, this tool provides the flexibility to create groups that fit your classroom structure.
2. Bad Pairings and Wildcards
Certain students may not work well together. The Classroom Groups Manager allows you to save these bad pairings, ensuring they are not grouped together. Additionally, the tool prevents bad pairs from becoming the “odd one out” (wildcard) in groupings where the total number of students does not divide evenly into groups.
If a wildcard needs to be created, the system intelligently chooses someone not involved in a bad pairing and allows them to join a group of their choice. Currently, this feature is not active in circle arrangements or groupings around selected students, but works perfectly for fixed desk or standard group arrangements.
Random Student Selector
The random student selector ensures all students have an equal chance to participate. It randomly selects a student, highlights their name in fluorescent green, enlarges their desk/rectangle, and keeps track of the last selected student. This ensures more inclusive and balanced class participation, and that no student is called on repeatedly in succession.
Fluorescent green rectangle represents a randomly chosen student. Gold is a wild card that can choose their own group.
4. Visual Group Layouts
The tool visually organizes groups directly onto the Google Slides canvas, providing an instant view of your classroom seating or group assignments. It places students into rectangles, which can be customized to fit your class’s layout. With drag-and-drop functionality, you can adjust the layout on the fly, enabling real-time flexibility.
5. Grouping Around Selected Students
This feature allows you to assign certain students to specific groups (e.g., group leaders or students needing extra support), while the remaining students are evenly distributed among them. This ensures balanced group dynamics and gives teachers strategic control over group composition.
Group leaders set with other students arranged around them
6. Arrange Students in a Circle
For certain classroom activities, like group discussions or icebreakers, you may prefer students to sit in a circle. The tool supports a circle arrangement feature, which automatically spaces students evenly in a circular layout, while
taking bad pairings into account to avoid conflicts within groups.
Assign Names to Fixed Desks Without Rearranging
The Assign Names to Desks feature respects the current layout and orientation of desks that a teacher has manually arranged on the slide. Whether desks are rotated, repositioned, or grouped in non-traditional ways (such as bean bags, couches, or different seating zones), this feature simply assigns student names to the desks as they are.
This ensures that teachers can maintain their customized classroom environment, allowing for exact positioning based on various learning areas or furniture setups. Unlike other group creation functions that rearrange desks into grids or circles, this feature keeps your specific arrangement intact and focuses only on assigning names.
How to Use the Classroom Groups Manager Tool
Step 1: Add Your Students
You can input student names into the tool’s sidebar in multiple formats:
Space-separated: “Ashley Catherine Derek Liz Milo Oliver Raysen Alexandra”
A combination of both: “Ashley, Catherine Derek, Liz Milo Oliver Raysen, Alexandra”Step 2: Create GroupsAfter entering your students’ names, select the group size (e.g., groups of 4) or assign specific students as group leaders. The tool will automatically balance the groups, taking into account any bad pairings you have saved. You can also group students around selected individuals, perfect for strategic group formations.
Step 3: Make a Duplicate Slide for Each Class
For teachers managing multiple classes or needing to create new group configurations over time, duplicating a slide is essential. This ensures that previous groupings are preserved, allowing you to experiment with new arrangements without losing the original layout.
Here’s how to duplicate a slide in Google Slides:
Select the Slide: In the left sidebar of Google Slides (where all the slides are listed), find the slide that contains the groups or seating arrangement you want to duplicate.
Right-Click the Slide: Right-click on the slide you wish to copy. A drop-down menu will appear.
Click “Duplicate Slide”: From the drop-down menu, select Duplicate Slide. This will create an exact copy of the slide, which you can now modify as needed.
Rename the Slide: Double-click the slide name (usually visible in the notes area or in the sidebar) and rename it according to the class or activity you’re working on (e.g., “Block 2: Science Project Groups”).
By duplicating slides, you can create different group configurations for different classes or activities, while keeping a history of past groupings. This is particularly helpful if you want to revisit a previous arrangement or quickly switch between different layouts for various lessons. It also ensures that you don’t lose the initial setup when experimenting with new configurations.
Practical Applications for Teachers
The tool isn’t just for group formation. Here are a few other ways it can be useful in your classrooms:
Differentiating Instruction: Assign stronger students as group leaders, ensuring every group has a capable peer for guidance.
Avoiding Conflicts: Use the bad pairings feature to avoid putting certain students together, preventing disruptions or conflicts during group work.
Creating Varied Groupings: Over time, you can create different configurations by duplicating slides, saving past groupings, and re-using them to keep things fresh.
Using the “Add Class Name/Label” Feature
Labeling your slides is important for keeping track of different groupings or activities over time. You can easily add class names or labels to your slides to, for example, “Block 2: Science Project Groups”
Block 2: Science Project Groups
Reading Discussion Partners
By duplicating slides and applying unique labels, you can save past groupings for future reference. This means you can easily switch between different configurations and ensure students experience varied group dynamics over time.
The Classroom Groups Manager is designed to offer flexibility in how teachers manage student groups. Here are just a few ways the tool can be used:
Differentiate Instruction: Assign strong students as group leaders, ensuring each group has guidance from a capable peer.
Avoid Problematic Pairings: Use the bad pairings feature to avoid placing certain students together, allowing you to prevent known conflicts in group work.
Create Varied Groupings: Over time, you can create different group configurations and save past groupings by duplicating slides. This ensures good variation and prevents the same students from working together repeatedly.
Manually Adjusting Text for Long Names
Although the tool resizes text automatically based on name length, some longer names may require manual text fitting. To make sure the text fits properly within shapes, you can set the text padding to zero:
Select the shape containing the student’s name.
Open the Format Options panel.
Scroll to Text Fitting and set the left, right, top, and bottom padding to zero:
This ensures that even long names fit within the allotted space. Note that as of this writing, the Google Apps Script API does not allow programmatically changing the text fitting/text padding.
Conclusion
The Classroom Groups Manager simplifies the complex task of managing classroom groups. Whether you’re creating groups for discussions, seating arrangements, or projects, this tool provides the flexibility and control needed to organize your class efficiently. With features like bad pairings, random student selection, and grouping around key students, it saves valuable time while hopefully fostering more dynamic and effective student collaboration.
Try it in your classroom and see how it transforms the way you manage student groups!
Make Words Game:
Implementing a Classic Pen & Paper Game in Google Sheets
Introduction
Word games have always been a popular form of entertainment and education, with classics like Boggle, Scrabble, and the New York Times’ Spelling Bee captivating word enthusiasts worldwide. Growing up, I played these games with my family using paper and pencil, which created wonderful memories and a love for word puzzles. Inspired by these timeless games, I set out to create MakeWords, a Google Sheets-based game that brings the excitement of word puzzles into a digital and easily accessible format. This game isn’t just a fun way to pass time; it’s also a valuable educational tool, particularly for ESL and ELL students.
Project Overview
Objective: Form as many smaller words as possible from a given longer word.
Rules: Players are given a long word and must form as many valid smaller words as possible using the letters from the long word.
Video Preview
Educational Benefits
Vocabulary Expansion: Players are encouraged to think of and form longer, more complex words, helping them expand their vocabulary.
Strategic Thinking: The exponential scoring encourages strategic thinking, as players need to weigh the benefits of finding longer words against the time it takes to think of them.
Engagement: The increasing points for longer words make the game more exciting and competitive, which can help maintain students’ interest and engagement.
Reinforcement of Spelling: Regularly forming and validating words helps reinforce correct spelling and word usage.
Gamifying Learning
MakeWords is a powerful tool for engaging students through gamification. Teachers assigning this game are leveraging the principles of gamification to make learning fun and interactive. Here’s how:
Engaging Through Gamification
Making Learning Fun: By turning word practice and spelling into a game, students are more likely to enjoy the learning process. The competitive element, where students aim to find as many words as possible from a given word, and the longer the word, the more points are awarded.
Attention to Detail: The game requires students to pay close attention to the letters in the given long word. They need to ensure they are using the letters correctly, checking for duplicates, and verifying the validity of the words. This meticulous approach enhances their attention to detail and spelling accuracy.
Fostering a Competitive Learning Environment: By choosing the same starting long word,and playing simultaneously, users can compete to see who can get the most points in the given time. This healthy competition can drive players to improve their word recall and spelling skills as they strive to outperform their peers.
Tracking Performance and Growth
Timestamps for Tracking Progress: Each game session is automatically named and saved with a timestamp. This feature allows teachers and parents to track the progress of students over time. They can see how students are improving in their ability to recall and form words.
Performance Review: By reviewing past game sessions, shared with teachers or parents, it’s easy to identify patterns in a student’s performance. Teachers can see which types of words students struggle with and provide targeted support to help them improve.
Growth in Word Recall and Retrieval: As students play more games, their ability to recall and retrieve words is likely to improve. Teachers can use the timestamps and saved game sessions to monitor this growth, providing evidence of learning progress over time.
Data-Driven Insights: The structured data from each game session offers valuable insights into a student’s learning journey. Teachers can analyze this data to understand individual strengths and weaknesses, adapting their teaching strategies to better support each student.
Practical Implementation
Assigning the Game: Teachers can easily assign MakeWords to students in Google Classroom. The game is accessible and straightforward, making it easy for students to start playing and learning immediately. Teachers can keep track of usage; this shared access ensures that those involved in the student’s education can see their progress and provide encouragement or additional support as needed.
Encouraging Continuous Improvement: With each game saved and accessible, students can see their own improvement over time. This visibility can be a powerful motivator, encouraging them to keep practicing and improving their word skills.
Technical Setup – Google Sheet Structure
Dictionary Sheet: Contains a list of long words organized alphabetically into columns (A-Z).
This structure significantly improves efficiency by limiting the search space. Instead of searching through one long column containing the entire dictionary, the search is confined to a single column corresponding to the first letter of the word, making lookups faster and less resource-intensive.
Game Sheet: The gameplay takes place here, where players enter their words and see their scores.
Google Apps Script
Random Word Selection: The script draws a random long word from the “Dictionary” sheet.
Word Validation: Players enter their words in designated cells, and the script checks their validity, ensuring they can be formed from the letters of the long word.
Scoring System: The script calculates points based on the length of the words and handles duplicate entries and invalid words.
Feedback
Providing clear reasons why a word is invalid is vital feedback that enhances the learning experience in “Make Words.” When players receive specific feedback, such as a word being invalid due to incorrect letters or being a duplicate entry, they can quickly adjust their strategies and avoid making the same mistakes. This targeted feedback not only aids in faster learning but also keeps the game challenging and educational. Knowing why a word is invalid or seeing their scores improve encourages players to think more critically and enhances their problem-solving skills, making MakeWords both a fun and valuable educational tool.
A key feature of MakeWords is the use of toast notifications. These are small, non-intrusive pop-up messages that appear briefly at the bottom of the screen. The name “toast” comes from the way these notifications pop up like a slice of toasted bread. Toast notifications are particularly effective because they provide feedback without interrupting gameplay. Unlike traditional dialogue boxes or alerts that require user interaction to close, toast notifications allow players to continue playing seamlessly. Players are informed about the validity of their words and their points without having to click anything to dismiss the notification. This ensures a smooth and engaging gaming experience.
Toast notifications provide instant feedback on the validity of their words and the points they earn. This real-time response keeps students engaged and helps them learn from their mistakes without interrupting the flow of the game. Moreover, this immediate feedback is crucial for maintaining high levels of motivation and engagement, as it helps players understand the rules better and improve their word-forming skills dynamically.
Smart Scoring Method
One of the unique aspects of this game is its smart scoring method, designed to encourage players to find longer words.
This exponential scoring system motivates players to find longer words, as each additional letter significantly increases the points earned. It turns the game into a more strategic and engaging activity.
Performance Optimization with Binary Search
One significant challenge was ensuring the game ran smoothly and updated scores correctly during fast play. This required an efficient way to validate words against a large dictionary.
Efficient Google Sheet Structure
Dictionary Sheet: Contains a list of long words organized alphabetically into columns (A-Z). This structure improves efficiency by limiting the search space. Instead of searching through one long column containing the entire dictionary, the search is confined to a single column corresponding to the first letter of the word, making lookups faster and less resource-intensive.
Why Binary Search?
Binary search is a powerful algorithm for finding an item in a sorted list in logarithmic time. Imagine you’re playing a number guessing game, where you have to guess a number between 1 and 100. Each time you make a guess, you’re told whether the number is higher or lower than your guess. You might start by guessing 50. If the number is higher, you then guess 75, and if it’s lower, you guess 25. By continually dividing the range in half, you quickly narrow down the possibilities.
Applying Binary Search to Word Validation
By organizing the dictionary sheet alphabetically into columns based on the first letter of each word, I leveraged binary search to quickly validate words. Here’s how:
Alphabetical Columns: The dictionary is divided into 26 columns (A-Z), each containing words that start with the corresponding letter.
Sorted Words: Within each column, the words are sorted alphabetically.
Example:
Suppose a player enters the word “cinema”. The script:
Locates the Column: Identifies the relevant column ‘C’ for words starting with ‘C’.
Performs Binary Search:
Finds the middle word in the ‘C’ column. With 24,797 words, the middle word would be around the 12,399th word.
Let’s assume the middle word in the 0 to 12,398 range is “cobra”.
Compare “cinema” with “cobra”:
Since “cinema” comes before “cobra” alphabetically, search the first half of the column.
Narrow the search range to 0 to 6,199.
Find the new middle word in this range, let’s say it’s “cherry”.
Compare “cinema” with “cherry”:
Since “cinema” comes after “cherry”, search the second half of this range.
Narrow the search range to 3,100 to 6,199.
Find the new middle word in this range, let’s say it’s “clementine”.
Compare “cinema” with “clementine”:
Since “cinema” comes before “clementine”, search the first half of this range.
Narrow the search range to 3,100 to 4,649.
Find the new middle word in this range, let’s say it’s “cite”.
Compare “cite” with “cinema”:
Since “cinema” comes before “cite”, search the first half of this range.
Repeat this process until “cinema” is found or the range is exhausted.
Benefits of This Structure:
Notice how, in just 4-5 comparisons, we got down to less than 1,000 options from the over 24,000 words starting with C. Compare this method to going through the entire dictionary of over 150,000 words every time we want to validate a word! Binary search can reduce the search space significantly, making it ideal for handling large datasets and ensuring quick word validation even during fast-paced play.
Code Snippet for Binary Search:
arr: The array (list) of sorted words being searched.
target: The word you’re looking for.
left and right: The starting and ending indices of the current search range.
mid: The middle index of the current search range.
midValue: The word at the middle index, compared to the target word.
Implementation Details
Step-by-Step Guide
Set up the Google Sheets: Create a “Dictionary” sheet and a “Make Words Game” sheet.
Google Apps Script: Implement the script to handle word selection, validation, and scoring. Here’s a key snippet from the script:
Start Playing: Draw a random word and begin forming smaller words. The script will handle validation and scoring in real-time.
Breakdown of the Scoring Formula
The formula used in cell F2 to calculate the total score is:
SUMPRODUCT Function: This function multiplies corresponding components in the given arrays and then sums the results. It’s used here to handle both numeric and text entries.
IF Function:IF(ISNUMBER(B4:B45), B4:B45, 0) checks each cell in the range B4. If the cell contains a number, it returns that number; otherwise, it returns 0. This ensures that only valid points (numbers) are included in the sum.
ISNUMBER Function: This function checks whether each cell contains a number. It’s essential for filtering out non-numeric values like text or empty cells.
Sum Calculation: The formula does this for three ranges: B4, D4, and F4. It sums the valid numeric values from these ranges separately and then adds the results together to get the total score.
This formula efficiently calculates the total points from multiple columns, ensuring that only numeric values are considered, which is particularly useful during fast-paced play.
Conclusion
The MakeWords game is a fantastic way to bring the joy of classic word games into the digital age, using tools like Google Sheets and Google Apps Script. Whether you’re an educator looking for a fun classroom activity or a word enthusiast, this game offers endless possibilities for learning and enjoyment. I invite you to try creating your own version and share your experiences!

Google Sheets is a game-changer for managing tournament brackets.
Welcome to the world of tournament brackets reinvented! In this article, I want to take you on a journey that began with my fascination for brackets during my elementary school days. I vividly remember how our principal would post these elaborate double-elimination tournament brackets, drawn with markers on butcher paper, for various school sports, chess competitions, and other tournaments. I would stare at them, eager to figure out the underlying logic. How could the brackets be structured to accommodate scenarios other than 4, 8, or 16 participants? This curiosity stuck with me, and as technology advanced, I continued to think of innovative solutions to simplify the bracket management process.
As an educator and a tech enthusiast, I have frequently observed the struggles of managing tournament brackets. Whether it’s in a classroom setting or a community sports event, maintaining tournament brackets can be notoriously challenging. Handwritten brackets necessitate rewriting names, erasing and correcting mistakes, and a plethora of papers and posters. The process is not just tedious but is also prone to errors. Additionally, subscription-based digital solutions pose their own set of problems such as subscription, privacy concerns, payment issues, and rigid UI. This led me to a question – Can Google Sheets offer a better solution?
Research, Tinkering, and Discovering
In March 2022, prior to ChatGPT, I started to explore the potential of Google Sheets for creating dynamic tournament brackets. The initial design concept was to use the cell border lines strategically to create the tournament bracket lines on which to write player names and to guide the rounds of elimination. This required meticulous work, but I think it was worth it.
One strong advantage of using Google Sheets is the automatic advancement of winners to the next round through cell formulas and functions. However, this would require the user to indicate who won. An early feature I envisioned was the use of checkboxes to indicate the winners. I found a snippet of code online that could turn checkboxes into radio buttons, (credit toBen Collins): https://www.benlcollins.com/apps-script/radio-buttons-in-google-sheets/. Being able to click once to update match winners was essential for updating the tournament brackets efficiently. I customized this code to suit the specific needs of the tournament brackets.
The journey continued as I experimented with cell formulas and explored the possibilities of Google Apps Script. Later that year, I found an invaluable ally in ChatGPT, which greatly simplified the creation of cell formulas and scripts.

Running the unverified Google Apps Script I’m sharing is a safe and straightforward process. Here’s what you can expect:
Authorization Request: When you run the script, you’ll encounter an authorization request. This is a standard procedure and necessary for the script to access specific data within your Google account.
Clicking “Advanced”: During the authorization process, you will be prompted to click on the “Advanced” option. This step allows you to review and understand the script’s permissions before proceeding.
Allowing Script to Run: After clicking “Advanced,” you might encounter a warning about the script being unverified. This doesn’t mean any malicious activity is occurring. To proceed, simply select the option to allow the script to run.
Please note that by allowing the script to run, you are basically giving it permission to read from and modify the contents of cells in the sheet. This is necessary for the script to perform the requested actions for you.
Additionally, I want to clarify that the code for this script was authored with ChatGPT. However, it is self-contained and does not involve any external APIs or calls to AI when it is run. Your data and device will remain secure. Feel free to use and modify the code as per your requirements.
I hope this tool simplifies your classroom management and fosters a collaborative and inclusive learning environment. If you have any questions or feedback, please don’t hesitate to reach out.
I got a great suggestion from Nirmala Sankaran, Co-Founder of HeyMath, to include the total possible words for a given board. This required iterating over the dictionary and checking if each word is valid for each board, given the game rules.

Implementing Tangrams in Google Slides makes a lot of sense for online/blended learning. It builds multimedia literacy skills, visuospatial skills, and a deeper understanding of how Google Sheets work.
This material is suitable for primary mathematics, PYP Design, and MYP Design
Creating the Tangrams set from scratch in Google Drawings is a good high-ceiling activity, and a way to teach unit conversion, proportions, aspect ratio, and more.
