Optional Parent Activities:1. Loo at a ruler with your child and discuss the numbers on the ruler. Determine that they are ordered fromleast to greatest. The ruler is a model of a number line. Ask your child questions about the number on the ruler,(e.g. "What numbers are greater than 10? Less than 4? What number is between 7 and 9?")

2. Have your child draw a number line and label the points between 2 specified numbers on the number line(e.g. 30-42). Ask questions similar to those above.

3. Have your child practice addition and subtraction on the number line. Give directions such as, Move back4 spaces from 14 and tell me what 14-4 equals".
