In my sixth grade integrated math and ELA class at Quest to Learn, students play a board game called Caterpillar to learn about probability and statistics. As a founding teacher at the NYC public school with a unique game-like learning model (currently in its fifth year), I have worked through many iterations of this game and how it affects students' mathematical experience over the years.
What makes Caterpillar particularly effective is that, as my students are introduced to the game, they are playing it through three different learning lenses:
- The basics of the game -- rules, components, core mechanics
- The learning goals of the game -- how to successfully win
- The skills they develop -- how to use the game's mathematical concepts in the real world, as they apply their content knowledge to modify the existing game
Caterpillar offers a great example of how to level your students up through any game so that they master the gameplay, master the learning goals, and apply what they've learned in one seamless experience.
Mastery of Gameplay and Rules
Caterpillar is a two- to four-player board game, played with colored blocks, two dice, and a frequency chart for recording each dice roll. The goal is to build the longest caterpillar with blocks by the end of the game. Each player begins the game by placing two blocks on any two mushroom spaces they choose. Each turn consists of a player rolling the two dice and recording the sum on the frequency chart. Any player with a block on a mushroom space touching the sum rolled receives an extra block of his or her color. Each turn also includes the opportunity to place accumulated blocks in order to build the longest caterpillar on the board.
The game ends when there are no more spaces available on the board. Players then reference their dice rolls on the frequency chart to determine the most frequently rolled number. That number is the "bird," which eats the caterpillars at the end of the game. Players must remove pieces from any space around the number that has been determined to be the bird. The player with the longest caterpillar intact at the end of this explosion is the winner!
Due to the content level, Caterpillar is most appropriate for middle school grades (6-8).
Mastery of Learning Goals
The learning goals in Caterpillar are for all students to master the related probability and statistics content by developing strategies to win the game.
How to: Through the first few game plays, your students might begin to realize the distinction between a "good" and "bad" first move, based on where they place their first two blocks on mushroom spaces. You can help students notice that these spaces correspond to the most and least frequently rolled two dice sums, which is a concept that students are introduced to in the game, as they start noticing that sevens are rolled much more frequently than twelves, and so on. Students quickly make the visual connection between the theoretical probability of rolling two six-sided dice many times and the experimental probability of the same event through rolling the dice in the game and recording them in the frequency chart. Have all classes record each dice roll on a larger frequency chart in the classroom, and a bell curve begins to appear as classes compile all the data through many rounds of gameplay. This allows students to make connections between the traditional content and the real world experience of the mathematics in games.
Applying New Skills in Real-World Context
The ultimate goal in Caterpillar is for students to apply their mathematical knowledge by working together to develop modifications to improve the game. This challenge embodies one of my favorite phrases: "Math is a verb." Students are asked to do new things with the mathematics they're learning, and it looks different to each student.
Task your students with playing the role of game designer by making changes to the game board, rules, and/or core mechanics, and by collecting data to justify the changes they choose to make. You can do either of these:
- Ask students to make a simple modification, like filling in a blank game board with new number positions.
- Let students conduct their own inquiry into deeper modifications by:
- Identifying the components of the original game that they enjoy and wish to keep in their modified version.
- Brainstorming around the components that they wish to modify, delete and/or add to the original.
You can then have students draft quantitative research questions based on the parts of the game they wish to change, such as:
- What happens to the game if you use three dice instead of two?
- What if you use four-sided dice?
Groups can compile data to justify their Caterpillar mods by asking their research questions to classmates, peers, and other teachers and staff familiar with the game. Some of my students' past modifications included:
- Adding a spinner
- Building and using a 3D game board
- Using three dice
- Creating a version of the game in Minecraft
This modding project allows students to stretch their understanding of the mathematical concepts in an engaging, challenging context that reflects their interests as both gamers and designers.
Doing the Math
Having ownership of their mathematical explorations allows students to develop and sharpen their existing skillsets in order to meet (and hopefully exceed) new challenges. Through experiments with setting appropriate goals and increasing expectations for students by providing different levels of challenge in a lesson or activity, you can model the process of continuous learning, and help students learn how to keep challenging themselves. Games like Caterpillar allow students to proceed at their own pace, to fail and fix the mistakes they make, and to ultimately give real value to mathematics through experience. Math isn't something you learn -- it's something you do.
