You help the Quadraticans by solving algebra problems in the four areas of the game. In the Challenger you learn and practice algebra via video chalkboard, example window, practice window, or word problems. In the Decoder you match equations with written descriptions of equations.
Correct answers provide pieces of a puzzle.
When all the pieces are collected, you must decode them in order to select a correct vocabulary word. The Simulator provides practice with finding and naming points and slopes on a coordinate grid with four quadrants. In Red Alert, you defend the buildings of a city by using a laser beam to blow up incoming space ships which otherwise explode upon landing. Copyright 1998 TERC, All Rights Reserved.
