How easy and fun is this? Here's what you need: Froot Loops cereal (or any off brand) ;), picture of a Rainbow (I laminate mine so we can use them in preschool). But your child can draw a picture of a Rainbow as well to use!
Here's what you do: Give your child a cup of cereal and have them match the colors of the cereal to the rainbow. This yummy snack can help reinforce the following concepts: color matching, color naming, more, less, and most.
