Popsicle sticks can be such fun! We even built a whole castle out of them when we were studying knights/ castles/ medieval times. (The catapult was AWESOME!)
Lately, I have been making shapes and having Tornado copy my shapes and then make his own. He also sorts by colors and counts them and returns them to their container. Plus, they are wood. And anything wooden is just fun to touch.
I found these printables here for popsicle templates: sol da eira
