Related Activities to Try at Home

Dear Family,

The activities suggested below are related to the mathematics we are currently working on in school. Doing these activities together can enrich your child's mathematical learning.

Making One Dollar In class, we are learning about coin values and equivalencies of one dollar. Examine coins, and ask your child to tell you about each coin. Discuss how much one dollar is worth in pennies, nickels, dimes, and quarters. Talk about equivalencies: “Here are 4 quarters. How much is this worth? Can you find another way to make $1.00?” “I have 7 dimes. How much more do I need to have $1.00?”

15 Minutes More In this unit, we are continuing to work on telling time to the quarter hour (e.g., 12:45, 3:15). At home, your child can continue to work on telling time to the hour, half hour, and quarter hour. See whether your child can figure out what the time will be 1 hour, half an hour, or 15 minutes from now. “It is 6:15. What time will it be in 15 minutes? Can you make a picture of what the clock will look like then?”

Solving Addition and Subtraction Problems Look for 2-digit addition and subtraction situations at home, such as the following:

  • • There are 36 beans in this jar and 42 beans in this jar. If we pour all of the beans from both jars into a bowl, how many beans will there be altogether?

  • • If you have 95 cents and you spend 30 cents, how much will you have left?

Have a pencil and paper handy, and encourage your child to explain how he or she is solving the problems.
