Maths: Year 3 & 4 National Curriculum, topic 5.3.2
Using Times Tables
We can use the times tables up to 12 to divide and multiply numbers.
Using times tables
- We know from our 9 times tables that 7 x 9 = 63.
- So that means 63 ÷ 7 = 9.
- That also means 63 ÷ 9 = 7.
- The division facts match the multiplication fact that we used.
Multiplying ten times bigger
- Next, we can look at the number being ten times bigger.
- If I know 7 x 9 = 63 then I know:
- 70 x 9 = 630
- 7 x 90 = 630
- 70 x 90 = 6,300
Dividing ten times bigger
- Because we know how to multiply when the numbers ten or a hundred times bigger, we also know how to divide too!
- 630 ÷ 9 = 70
- 630 ÷ 7 = 90
- 630 ÷ 90 = 7
- 630 ÷ 70 = 9
Test yourself on Using Times Tables
From our 11 times tables, we know that 3 x 11 = 33.
Using this knowledge, what is 30 x 11?
From our 12 times tables, we know that 5 x 12 = 60.
Using this knowledge, what is 600 ÷ 120?
From our 9 times tables, we know that 4 x 9 = 36.
Using this knowledge, what is 3,600 ÷ 9?
