Dinosaur week: Fun & Simple dinosaur activity for kids! Maybe for older kids give each shape a numerical value and have them add how much their dino is worth. Can use with class to compare/contrast amounts, etc.
craft sticks and velcro, these can be arranged to make shapes and letters (great busy bag idea!) L and I had a blast painting stitcks today and I bought sticky velcro circles at Michael's. We'll see if they are a hit on our next trip!
