K.A.
When I was a pre-school teacher we would take just a little bit of washable paint, and mix it with shaving cream. I just let them smear it all over the table and then when they were done I took a piece of paper and set it on top and make a sort of print from what was smeared on the table. Its a great sensory activity for young ones. I also took all the paper off of crayons and put the little bits in to muffin tins and baked them until they all melted. Then, after they dried I had big chunky crayons perfect for little hands. The important thing with art at this young age is not to expect perfect little crafts. They are really just exploring new things. When children are ready to color inside lines they will make there own!
