This unit lays the groundwork for the mathematics we do all year. We will focus on counting by 1s and by groups of 5 and 10, identifying and recognizing coins and their values, using what we know to add and subtract numbers, developing fluency with the addition and subtraction facts, and understanding and solving a variety of story problems that involve addition and subtraction. In our math class, students engage in math problems and activities. They are frequently asked to share their thinking about a given problem. Most important is that children accurately solve math problems in ways that make sense to them. At home, encourage your child to explain the math thinking that supports those solutions.

Activities to Try at Home
Coins In class, we are learning about coins and their values. At home, your child can examine coins and talk with someone about what they notice. Ask them questions such as, “What is this coin called?”, “Can you find a quarter?”, and “How much is each coin is worth in pennies?” You can also discuss questions such as: “Here are two dimes. How much is this worth? … Can you find another way to make 20¢?” or “Let’s trade coins. I’ll give you 2 nickels for 1 dime.”
Pockets at Home In school, we count the number of pockets that people have on their clothes in several different ways. At home, your child can find how many pockets people in your family are wearing—individually and altogether. Your child may be interested in comparing the number of pockets on different days (on school days and on weekends) or at different times of the day (school/work clothes, play clothes, pajamas . . .).
Counting by Groups Look for opportunities to practice counting by 2s, 5s, and 10s. Count together and see how high you can go. Think about situations that involve equal groups. Pose questions such as these:
“If you have 8 pairs of socks, how many socks do you have? "
"If there are 5 people sitting on a bench, how many toes will there be?”
