Free Math Game: Challenging Multiplication Grid

How well do you know your multiplication facts?
Are you comfortable with digits beyond 12?

Here's a chance to test yourself (and your students) with this fun, challenging game.  It's a Speed Grid Challenge, and I'll admit that it defeated me quite a few times.

This is a good mental math activity (with introductory algebra skills) that challenges thinkers to solve by choosing numbers from a grid.  Sounds kind of easy, doesn't it?  Not if you're unable to quickly calculate a number times 13, 15, or higher!  

You can select how many problems to solve in however many minutes you choose.  The default, 8 questions in 2 minutes, is a good place to start.  If you are able to do that comfortably, up the stakes to more problems and/or less time to solve.  Conversely, if the default is too challenging (ahem), feel free to decrease the number of problems, or increase the time limit.  Once students find a comfortable pace, encourage them to strive for a more challenging pace.

If you're looking for math activities for kids, especially ones who've mastered their multiplication facts, this free game is a good mental exercise.  It would be a good math center or computer station activity.
Try it yourself, and with your math class.  It's one of my favorites!
