J had him flying the airplane under, over, and around, and had him learning these spatial concepts (and prepositions--yay!) while doing his very active boy thing.
I, of course, ran to get the camera thinking, "Honey, you are about to be a blog post."
What's not to love about this simple learning within play activity with objects you probably have around the house? If not legos, use blocks, If not blocks, use tupperware or cereal boxes.
I'm also glad I snapped a few pictures because I often have trouble recreating the masterpieces that Daddy builds without a visual image!
