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!
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.
Look at the examples below:
Nate reads 25 pages of a book every day. How many pages did he read this week?
Ask yourself:
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. How many pages did he read this week?
Let's review:
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.
