I could totally do this with money-- dollars on a pumpkin then popsicle sticks with bills and coins that add up to the amount. Addition/subtraction sorting - child needs to determine which sticks add up to the number on the bucket.
Number magnets to keep track of kids you allow to leave the room. Use a cookie sheet with glass stones glued to scrapbook paper and a magnet. then trim in fun duct tape! (The cookie sheet magnet board is pretty sweet for multiple different crafts.
for hand sanitizer! LEGOs suspended in a liquid soap dispenser. Fun to put out at a LEGO party or everyday use in your kids' bathroom! I'd probably search for a cuter dispenser, maybe more geometrical, but still such a cute idea!
other pinner says: "Homemade Oreos. Just like "real" Oreos, but without all the chemical garbage. I used Hershey's special dark cocoa, not dutched - resulting cookie tastes EXACTLY like Oreos, with same brown/black color.
