Encourage your school age children to create a collection. They might take a container or bag and collect some things that they find in nature while outside, or they might collect a variety of stray parts or art and craft materials from around your home. Ask them to sort their collection in different ways and involve the other children in viewing their collection and trying to discover their sorting pattern. Challenge them to sort their collections in multiple ways and describe the rules they have established for sorting.
Goal: Children will practice sorting materials by different attributes and describing the different qualities of the materials in their collection.
