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.
Sam has 12 stickers.
James has three times as many as Jake.
How many does James have?
This question is a multiplication word problem.
We need to triple the number of stickers Jake has, to find out how many Jane has.
To triple a number, we multiply it by 3.
12 × 3 = 36
James has 36 stickers.
Now let's try an example question together.
My grandfather is three times my age.
He is 63 years old.
How old am I?
This is a division problem.
63 ÷ 3 = 21
I am 21 years old.
Now you're ready to try some questions by yourself.
