- Pearson Home-School Connection Activities
- Have your child help divide different foods into halves, fourths, and eighths, then count the pieces together: "one fourth, two fourths, three fourths...."
- Explore equal parts with objects as well. Give your child a number of equally sized objects (e.g., 12 lima beans or 10 pennies) and ask her to show you how many different ways she can break the set of objects into equal parts. For example, when working with 8 beans, your child may make 2 equal parts by making 2 piles of 4 beans.

- Encourage your child to use place value language to explain how adding in the tens place is like adding in the ones place. “When I have a group of 10 ones, I can make a group of 1 ten.When I have a group of 10 tens, I can make a group of 1 hundred.”
- Encourage your child to explain what he is doing when solving problems to reinforce place value language. For example, to solve 46 – 7, your child might say, “First, I see that there are not enough ones to subtract in the ones place. So I need to change 1 ten for 10 ones. I had 6 ones, so now there are 16 ones!”

- When possible, encourage your student to explain their mathematical thinking by drawing a diagram or picture that links to their addition and subtraction problems. Explain that drawing pictures or using models also help to check his/her work.
- Encourage your child to think carefully about the numbers in a given problem before choosing a strategy. Ask her to look for numbers that are close to the next ten or numbers from which it would be easy to count on.
