Using multiplication to help solve word problems!

2
Sometimes we get maths questions given to us that are word problems. That means that it is actually written in words instead of numbers. However, word problems can be worked out using number sentences… we just have to decide what those number sentences are first.

3
Here is an example: What number when multiplied by 5 gives an answer of 45? What are the key words in this? What are the important bits of information? How can you write this as a number sentence?

4
? X 5 = 45 7 x 5 = 45 Did you use an inverse operation to work this out?

5
How many straws are needed to make 5 squares?

6
