ab: From the text: We have found Tetris to be an engaging tool for high school
geometry students to apply an isometry in context and to learn the
composition of isometrics. The game allows a player to rotate and
translate moving pieces to create full rows anywhere on the screen. We
begin this activity by playing one of the many online versions of the
game. This not only introduces the game but also generates student
interest and game-winning strategies. Playing the game allows students
to visualize and manipulate some of the isometries we have been
learning in class; even though the students are playing a video game,
they are learning content-specific applications of mathematics. After
students become familiar with the game, we present a mathematical
description of a move, explaining the correct notation and sequence
specific to compositions. The class discusses the required keystrokes
to rotate or translate a piece; verbalization of the terms “rotate"
and “translate" reinforces the students’ use of academic language.
Superimposing a coordinate plane on the Tetris board connects the
transformations to the coordinate plane.
