This is a great time to introduce colours using a rainbow theme since it goes with the crazy weather we get in the spring as well as St. Patrick's day. I find with the little ones that because they don't have a lot of skills to work with that focusing on just one colour can fall very flat as compared to older kids that can do more crafting and games related to it. I also find some kids learn what something is by learning what it is not. So for example if I am doing red and blue they can sort, compare light and dark tones, so it becomes using the colours I want them to learn to practice other skills - sorting, comparing, matching, naming.

I do a lot more games and activities rather than crafts with the little ones such as gluing a square of each colour onto a sheet of bristolboard and then sorting things to the squares - could be paper shapes, cars, blocks, pompoms, etc. Also gives the chance to talk about each item, how it feels, etc. too - again extra learning.
