Materials Preparation

Prepare the Clock Number Line. Use the Clock Number Line Master in the Teacher Guide to prepare a number line from 0 to 60 that will wrap around the large teaching clock so that the 0 and 60 will overlap. Cut out each of the number line segments. Tape or glue the segments together by overlapping the left edge of each segment with the gray end tab on the right side of the previous segment. See Figure 1 for an image of a completed clock number line.
