We are in our 1st week of MFW Rome to Reformation. One of the activities this week was to make a Roman tablet like school children used in Roman times. The book gives instructions using corrugated cardboard or in the Roman Empire book they suggested using balsal wood I wanted something a little simpler.
We used $1 unfinished wood frames from Michael's and non drying clay I think it was $3.59 for 4 colors which worked perfect for us.
We then gently pressed the modeling clay into the frame and used a playdough rolling pin to make it smooth.
