You've built model cars, and seen people modeling clothes, but modeling math problems? That doesn't sound so cool. However, it is a great way to solve word problems! Learn how with games and practice!

Quick Query

What do I know? What do I need to find out? These are the questions we must ask ourselves when faced with a multiplication word problem. Let’s look at some examples and see how models can help us solve them!

There are two parts to a word problem.

There is the *information*, or what you know. Then, there is the *question*, or what you need to find out. Tell a parent or teacher the two parts to a word problem. Then, look at the examples below:

How would you solve this problem?

- Nate reads 25 pages of a book every day. How many pages did he read this week?

Ask yourself:

- What do I know? Look for information in the problem.
*Nate reads 25 pages of a book every day*. How many pages did he read this week?

- What do I need to find out? What is the problem asking?
- Nate reads 25 pages of a book every day.
*How many pages did he read this week*?

- Nate reads 25 pages of a book every day.

Let’s review:

- We need to know how many pages Nate read in
*one week*. - We know one week is
*seven days*. - We know Nate reads
*25 pages every day*.

Now we can use a model to show the information:

Looking at our model, we can see that Nate read 25 pages for 7 days. To find how many pages he read in 1 week, or 7 days, we can multiply 25 and 7.

So, the answer is 25 x 7 = 175 pages. Nate read 175 pages in one week.

Let’s look at another example:

Rebecca bought 3 boxes of crayons. There were 120 crayons in each box. How many crayons did Rebecca have in all?

There were 120 crayons in each box. There were 3 boxes of crayons. To find out how many crayons there were in all, we can multiply 120 by 3.

120 x 3 = 360 crayons

Rebecca had 360 crayons in all.

Try some word problems on your own in the *Got It? *section.
