Great idea - I like how you give 1 simple idea (must be how my brain works!)did you see Elise's ideas here http://etadventures.blogspot.com.au/2012/02/playful-sanity-savers-and-book-give.html She had her kids sick and indoors for weeks. I love the shadow boxes and home movie idea.
I am a daycare provider and on occasion I have kindergarten kids it can be harder to keep them active than my preschool/toddlers this site has given me some awesome easy to create ideas, thank you!
What do you do if the holes in your colander are too big and the toothpick goes right through?
Just let your child poke them through. That is also fun for them. Maybe even more fun.
