Like with my 2 Year Olds, we hung the 3 Year Olds' valentine holders in the hallway and the parents helped the children distribute their cards before class started. Every Friday I have a parent helper, so I had her assist the children in making cupcakes. After gym, towards the end of our morning, the children frosted their cupcakes, added sprinkles, and enjoyed eating them. Very simple. Very fun. Just perfect for this age group!
