When K goes to karate I have to bring the little ones too. They are not always excited to sit and watch. I came up with this plan using pinterest and a couple of my own ideas.
It's a binder with several pencil pouches. Each pouch holds a different set of magnets. It fits in a messenger bag with a couple of cookie pans from the dollar store (steel, not aluminum).
I have foam shapes, dots, colored popsicle sticks with button magnets attached, bears, farm, construction site, sea life, space, alphabet, robots, and dinosaurs. Some of them came from play sets we already had, and for others I take stickers and attach them to a sheet magnet (a couple bucks at Walmart) and cut them out. Keeps them busy! Just thought I'd share.
