Introduce manipulatives for the lesson you want to teach. Manipulatives are concrete objects, such as an abacus, counters, geoboards, blocks, and beads--anything that can be used to represent abstract concepts. Allow your students to play with the manipulatives for at least one week before teaching your lesson.
Introduce the math concept you want to teach with a picture book. Check out the Children's Picture Books website for picture book suggestions for several different math lessons.
Distribute the manipulatives that you already introduced. Allow the students to work with their manipulatives independently and as a group to build their understanding of the concept that was taught.
Provide an activity that gets your students moving. For example, when teaching shapes students can go on a scavenger hunt to find shapes around the room.
