Racing Rectangles is a game that can help reinforce arrays and multiplication. Students, working in pairs, take turns rolling two dice. Each student must choose a different colored marker or crayon to use. The student outlines and fills in a rectangle that matches what they rolled.
For example, if the student rolled a 4 and 3, that student would fill in a 4x3 rectangle on the grid. The player then writes the total number of squares inside the rectangle.
A player loses a turn when his or her rectangle cannot fit on the game board. Play continues back and forth until neither player can't draw a rectangle.
Students count up their total of squares they colored.
The winner is the one with the highest number of squares filled in.
Here is an example of what a game board might look like...
