### Math Game- Racing Rectangles

Racing Rectangles

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...

Enjoy!

1. Hi Mary:

I think I'd like to use this when we review area next month. Thanks--as always--for sharing!

2. Awesome game! My students have begun learning how to multiply and we have already studied area-- a perfect activity for centers!

3. Love it! Thanks so much for sharing!

4. I like the idea and plan on using it with some slight variation to the rules, because I'm not sure I understand how the game would end. If "play continues back and forth until neither player can draw a rectangle", then the game wouldn't really be done until the board is completely covered since you can always roll snake eyes for a "1 x 1" rectangle. The game would get repetitive at the end. But maybe I'm missing something. Either way, thanks for the idea. I definitely be using it!

5. Hi Tyson... sorry I need to clarify here... play does end when for example, one player rolls the dice and can't draw a rectangle and then the next player rolls and can't draw either, then the game is over. Two "Can't Draws" in a row = end of game. They don't keep on going back and forth trying to roll a snake eyes (although if you needed to waste time they could :)
I hope this makes sense, when I say it in my head it is perfectly clear but in blog land... :)

6. Thanks for sharing! My boy and I will have fun with this.
