I bought a few packages of inexpensive sponges with the idea to make building blocks for the kids. With just 12 sponges, I made a huge pile of blocks that they spent the whole day learning, creating, and playing with. Just cut the sponges into various shapes! I cut most of the sponges into thirds to make the rectangle blocks. I cut a few of them in fourths to make squares. I also cut out a few triangles.
As soon as she sat down with the blocks, she was so excited to announce that she had made the letter T. Then we used the rectangle-shaped blocks to make the letters A, E, F, H, I, K, L, M, N, V, W, X, Y and Z.
She created a "Wreck it Ralph" town with the blocks. I also challenged her to see how high a tower she could make with them.
Before I knew it, the blocks were in the play kitchen and had became ingredients for recipes and, of course, pretend french fries.
