You know those foam letter puzzle pieces? I've mentioned them before, I'm sure. We use them for many other things besides just being a puzzle. This is one of those times. We placed them at the playdough table.
What I loved was watching as they looked for the letters they recognized from their names. Three year olds' names are very special to them, so those tend to be the first letters they know. We even started sounding out the letters!
A fun way to promote literacy at the playdough table!
