This activity needs some special supplies, so if you don't have them, it's OK to skip this one. But if you happen to have something to work as pretend nails (like golf tees, toothpicks, or corncob holders), something to work as pretend wood (like styrofoam or cardboard), and something to work as a pretend hammer (like a play hammer, a block, a water bottle, or a can)...you can play construction worker with me and work on fingertip strengthening!
