Hammering at Preschool
We were learning about the letter H and I thought it would be fun if they had a chance to hammer. We started out with white paper and it didn’t show up very well so we quickly switched to black paper. The kids chose the colored chalk they wanted. I had a cutting board lined with aluminum foil. Then I placed the black paper on top, then the chalk, then a piece of wax paper. The papers really did look cool and we had them up for a few weeks.
