Aphabet Balance Beam

I have tried several times to make a walking line for A using colorful electrical tape. Just something he can follow with his feet while concentrated on balance. He never likes it. But, as we were playing with our small alphabet foam squares he found the very long line irresistible to his little feet. Over and over he walked along his new balance beam. It wasn't long before we were changing the configuration to make a square, rectangle, zig-zag, and more. I'm thinking this is a perfect rainy day activity to get out some wiggles.
