I drew these up for some things I was making for my kids (I’m sure I’ll be sharing those here too!)
I printed these, laminated them and cut them out. Then I used a little magnetic tape on the back. I’ve been using these on our magnetic dry erase board to illustrate our activities while the children work with actual unit blocks.
I hope these are useful for you!
UPDATE on 3/15/11:
I made a new set that matches Math-U-See! I hope you enjoy them!
