Behind Your Back (freebie)

Here's a little geometry activity that I've seen a few times in some of my district math professional development.  It's a great one for challenging kids to think about shapes, their attributes, and the space they occupy.  

While one partner's back is to the smartboard or whatever tool a teacher has at their fingertips, the other partner faces the smartboard and describes the composite shape that they see while the other partner creates it without looking.  What fun and what a challenge!  They really have to know their stuff to pull this off.

Directions were given.  Questions were asked.  Clarifying took place.  I heard some great conversations!  Afterwards, one of my little guys patted me on the back and said, "That was pretty awesome!" 

I'd like to share the Smart Notebook file of composite shapes with you.  I'm crossing my fingers this will work.  If it doesn't, it won't be too hard to create your own.  Head here if you're interested.  (Please let me know if this doesn't work.)
