James Tanton would like this quilt story, though for him the puzzles came packaged in a pressed tin ceiling*. And this camping trip story will be perfect to take to my son's school, since they just got back from a camping trip. The problem solving strategies are also done nicely.

If I'm Math Mama, does that make Aunty Math my sister? ;^)

Let me know what you think of it.

* James tells this story in his introduction to Thinking Mathematics, Volume One:

My career as a mathematician began at age ten. I didn't realize this at the time, of course, but in retrospect it is clear to me that my journey into the rich world of mathematical play - and I use the wordplaywith serious intent - was opened to me thanks to a pressed-tin ceiling in an old Victorian-style house.

I grew up in Adelaide, Australia, in a house built in the early 1900s. The ceiling of each room had its own geometric design and each night in my bedroom I fell asleep staring at a 5x5 grid of squares above me, lined with vines and flowers.

I counted squares and rectangles in the design. I traced paths through its cells and along its edges. I tried to fit non-square shapes onto the vertices of the design. In short, I played a myriad of self-invented games and puzzles on that grid of squares as I fell asleep.
