In this activity, we will be solving problems by multiplying numbers by 3, 4 and 8.
We need to read the question very carefully to work out what we need to do.
Farmer Smith has 3 cows.
How many legs do his cows have altogether?
In this question, we have to multiply by 4 because cows have 4 legs!
The farmer has 3 cows, so we need to use the multiplication fact 3 × 4 or 4 × 3.
3 lots of 4 is 12.
So, Farmer Smith's cows have 12 legs in total.
Let's look at an example.
Example
Farmer Sarah has 5 pigs.
How many legs do her pigs have in total?
Answer
We know that pigs have 4 legs.
We know that Farmer Sarah has 5 pigs.
5 × 4 = 20
Now you're ready to try some questions. Good luck!
