Tuesday I introduced M. to the rough and smooth boards. We only worked with board #1 (front board in picture), though I did give him a few moments to explore boards 2 and 3. We touched "rough" and "smooth" several times then took turns wearing a blindfold and identifying rough and smooth by touch only. He really enjoyed the blindfold! We then spent a few minutes looking for over examples of rough and smooth in the playroom. Quick and fun lesson!
I made these boards the same time I did the color boxes. Having a handy husband means there's always lots of sandpaper and scraps of wood around!
