**Numbers Are Everywhere**

Family Note

As mentioned in a previous Family Letter, your child will have Home Link assignments throughout the year. This is your child’s first Home Link. Home Links appear in the first-grade program for many reasons:

- The assignments encourage children to take initiative and responsibility. As you respond with encouragement and assistance, you help your child build independence and self-confidence.
- Home Links reinforce newly learned skills and concepts. They provide opportunities for your child to think and practice at his or her own pace.
- These assignments relate the mathematics your child is learning in school to the real world, which is very important in the Everyday Mathematics program.
- Home Links will give you a better idea of the mathematics your child is learning. Listen and respond to your child’s comments about mathematics. Point out examples of numbers (time, TV channels, page numbers, telephone numbers, bus routes, lists, and so on). Children who do math with someone learn math. For this reason, Everyday Mathematics provides many counting and thinking games that you and your child will have fun playing together and that will help build a strong understanding of mathematics.

For this first Home Link, your child might look for a newspaper ad for grocery items, a calendar page, or a picture of a clock. This activity helps expand your child’s awareness of numbers in the world.
