Target Game

Target Game is a Grade 7 rational-number strategy game played with a calculator and one changing decimal value. Players begin with a random four-digit number, then take turns multiplying the current value by any decimal they choose, trying to land within the narrow target range from 499 to 501. The calculator is never cleared, so each player inherits the previous result.

Use it in a small group when students are reasoning about decimal multiplication, percent-like scaling, and how a factor changes magnitude. The shared running value makes estimation important because one move sets up—or disrupts—the next player.
