Give each group a strip of adding machine tape. Each group will then create a number line based on an assigned group of numbers. The teacher then tapes strips to the floor in correct order.
Teacher calls out a number.
The number line is cleared and the process is repeated, beginning with the number called out by the teacher. The groups reconvene to a whole class setting and share their march stories. Using a number line, what number could you choose that would make a new animal leader of the march. The teacher could fold or mark the paper strips before the lesson but allowing students to complete this part of the assignment provides an opportunity to make students responsible for organizing their own work to use cooperative strategies, and to demonstrate creative thinking. This activity can use number lines 1-20.
