In this activity, we will work on word problems using addition, subtraction, multiplication, and division.
Before starting to solve a word problem, we must check which operation is needed.
Let's take a look at a word problem together.
Jake has 17 stickers.
Jane has twice as many as Jake.
How many does Jane have?
This question is a multiplication word problem.
We need to double the number of stickers Jake has, to find out how many Jane has.
To double a number, we multiply it by 2.
17 × 2 = 34
Jane has 34 stickers.
Now let's try an example question together.
There are 18 children on a bus.
Three get off and two more get on. Then 10 get off and 4 get on.
How many are left on the bus?
This is a subtraction problem.
18 - 3 + 2 = 15 + 2 = 17
17 - 10 + 4 = 11
11 children are left on the bus.
Now you're ready to try some questions by yourself.
