I have found that my preschoolers behave much better if they feel included in our school day. Something as simple as paper shapes and glue can keep them busy for quite a while. These crafts work even better when you combine them with writings by Ezra Jack Keats because the illustrations are similar to the craft project, and the books are so wonderful!
Depending on the skill level of your child, they can cut out shapes themselves, or you can have older kids draw and cut the shapes for them.
Give your preschooler a glue stick and they are ready to create.
