In this activity, we will be solving problems by dividing numbers by 3, 4 and 8.
We can use known multiplication facts to make this easier.
We need to read the question very carefully to work out what we need to do.
Faith has 33 marbles.
She shares them into equal groups of 3.
How many groups can she make?
In this question, we have to work out how many groups of 3 we can make from the number 33.
We could use the fact 3 × 11 = 33 to help.
Counting up in threes is also a helpful strategy.
3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36
There are 11 lots of 3 in 33.
So, Faith could make 11 groups of 3 marbles.
Let's look at an example.
Example
Suzy has 18 sweets.
She shares them into equal groups of 3.
How many groups can she make?
Answer
We could count in 3s to 18
3, 6, 9, 12, 15, 18
We could also use this multiplication fact to find the answer.
3 × 6 = 18
Suzy can make 6 groups of 3 from her 18 sweets.
Now you're ready to try some questions. Good luck!
