Making word families is fun with this activity. You program one side of the plastic egg with letters and the other half with word endings like -at(b, c, th, r, f),
-oat, -ock, -ed. I have them take one egg at a time and practice saying the word and for older preschoolers they write them too!!! I also have a couple that are programmed opposite with th-(ere, e, at, ose, ink) and wh-(o, at, ere, y) with the endings on the bottom.
