So you've decided to spend some time using known times table facts to solve multiplication and division problems.
What are known facts?
In this activity, the known facts you will use are times tables and the related division facts.
By the end of Year 4, you are expected to know all of the multiplication and related division facts for all of the times tables up to 12x.
Why do we use known facts?
Known facts are a great way to work out related facts and to help you solve larger, more complex calculations.
A headteacher has 630 pencils. She shares them equally between the 7 classes in the school.
How many does each class get?
We know that 63 ÷ 7 = 9
So, we can use this knowledge to solve 630 ÷ 7 = 90.
Each class will get 90 pencils.
366 ÷ 6 = ?
Again, we can use known facts again to help solve this one!
We know that 36 ÷ 6 = 6
So, we know that 360 ÷ 6 = 60
366 ÷ 6 = (360 ÷ 6) + (6 ÷ 6)
= 60 + 1
So, 366 ÷ 6 = 61.
Now it's over to you to have a go at some questions on your own, good luck!
