Dear Family,

Today my class started

Chapter 3: Subtract to Solve Problems

Chapter 3: Subtract to Solve Problems. I will

be learning how to subtract large numbers and how to estimate differences.

Here are my vocabulary words and an activity that we can do together.

Key Vocabulary

difference The answer in a subtraction

problem.

regroup To take apart a number to write it in a

new way.

Fill a container with small objects

(pennies, buttons). Write down the

amount of items in the container. Then,

fill another container with other small

objects (popcorn kernels, beads). Do not

fill this container as full as the first. Write

down the amount of items in the second

container. Keep the amounts hidden and

ask a family member to guess the

amount of objects in each container.

Write down their guesses. Round each

guess to the closest ten and subtract the

amounts. Compare this number to the

actual difference in objects.
