Letter To Family - Practice Multiplying Numbers By 1 And 2-Digit Factors

Chapter 4 4

What We’re Learning

During the next few weeks, our math class will be learning about

and practicing multiplication of whole numbers.

You can expect to see work that provides practice with multiplying

numbers by 1-digit factors as well as by 2-digit factors.

As we learn how to multiply whole numbers and check the exact

answer using estimation, you may wish to use this sample as

a guide.

Guiding Your Child

Estimating to Check Multiplication

An estimate is a way to check an exact answer. An estimate can be compared to an exact

answer to help decide if that answer is reasonable.

First, multiply.

Then, estimate by rounding each

factor to the greatest place value.

3,471

Since 3,000 is close to the exact product, 3,471 is a reasonable answer. If an estimate is

not close to the exact answer, the problem should be redone.

During this chapter, students should continue to memorize the

basic multiplication facts.

Your Child’s Teacher
