If this is the first time you are introducing the dough then the following suggestions can be considered: Any three of the colors your child likes and recognizes.  Shapes and color mixing kit as it comes with colors, a shape cutter, a rolling pin, and a knife. Shapes and colors are something that the child picks up easily and at the very beginning. Rainbow kit- it has all the colors plus it has activities and games added specifically for the child to work on. It also has stamps to learn about cause and effect working on their hand & eye coordination.
