Our train table (we call it our building table) is just the right height for little arms to reach from underneath. I covered the underside with blue paper and masking tape and set out a tray of white paint and little sponges for the children to create their own clouds with.
It got a bit crowded but the children really held their own, negotiating for space and a turn at the sponges. They kept at if for maybe fifteen minutes before the lure of our shipping boxes called them to create am arching band.
I can't wait to see how tomorrow's class reacts to the surprise!
