Ration Rumble is a 2-player game that allows students to practice simplifying ratios. Players roll a die to identify a column in which to select a problem to solve. With each selected ratio, the player must simplify it. The first player to get 4 in a row - horizontally, vertically, or diagonally - wins the game. An answer key is included to assist students in confirming answers. This activity meets or exceeds the Common Core Standards of Mathematics and makes for a great class activity or learning center as students practice simplifying ratios.
