Quilt: What Can You Do with This?


[Ragged Squares Quilt photos used with permission from Crazy Mom Quilts.]

I know other teachers have done math quilts, but I’ve never gotten around to trying it in any of my classes. Still, this image caught my eye and practically begged me to make it into a math lesson for my elementary math club.

I thought of at least two ways I could go with this, but I bet that if we put our brains together, we can come up with even more creative ideas. So here’s the question, ala Dan Meyer:

  • What can you do with this?

How could you use this image as a springboard to doing math? What questions would you ask? What concepts would you try to get across? What would you follow it with? Please comment!

Tangrams and Other Dissection Puzzles

One of the things I meant to do with my elementary math class (the one that got canceled due to low enrollment):

And then we would play around with Tangram puzzles, and perhaps make up a few of our own.

Welcome to the inaugural edition of the Math Teachers At Play blog carnival! I hope you enjoy this collection of tips, tidbits, games, and activities for students and teachers of preschool-12th grade mathematics.

For this first carnival, I’ve drawn several recent posts from my blog reader as examples of the types of posts I’d love to include in future editions of Math Teachers at Play. I tried to find something for everyone, from multiplication drill for elementary students to advice for understanding high school math equations.

Let the mathematical fun begin…

2009 Mathematics Game

Have you made a resolution to exercise your mental muscles this year? Then please join us for the 2009 Mathematics Game. Here are the rules:

Use the digits in the year 2009 and the operations +, -, x, ÷, sqrt (square root), ^ (raise to a power), and ! (factorial) — along with parentheses, brackets, or other grouping symbols — to write expressions for the counting numbers 1 through 100.

  • All four digits must be used in each expression.
  • Only the digits 2, 0, 0, 9 may be used.
  • The decimal point may be used, as in .9, .02, etc.
  • Multi-digit numbers such as 29 or 902 may be used, but preference is given to solutions that avoid them.

By definition: 0! = 1 .
[See Dr. Math’s Why does 0 factorial equal 1?]

For this game we will accept: {0}^{0} = 1 .
[See the Dr. Math FAQ 0 to the 0 power.]
