Materials Preparation
Spinners. If you do not have clear plastic spinners to place over the Spinners 1–4 and 1–10 page, students can use paper clips and pencils. Straighten out one end of the paper clip, and place a pencil through the curved end. Then, put the point of the pencil on the center of the spinner, and spin the paper clip around the pencil, using the straightened end as the pointer. See Figure 1.
