# Number Facts

## What Are Number Facts?

Number facts are basic addition, subtraction, multiplication and division calculations that children should learn to recall instantly with no working out (in other words, they need to learn them off by heart).

Number facts are sometimes referred to as number bonds (addition and subtraction) and times tables with related division facts (multiplication and division).

By the end of  Year 3 children should  know:

• addition and subtraction facts to 20 (including number bonds to 20). This means all the different combinations of adding and subtracting numbers to a total of 20 (for example, 2 + 16 = 18, 17 – 5 = 12, 5 + 3 = 8, 6 + 7 = 13, 20 – 9 = 11, etc)..
• use the number bonds to 20 to derive related facts up to 100; for example, if they know 2 + 3 = 5 then they understand that 20 + 30 = 50.

• Multiplication and related division facts for the 2, 3, 5 and 10 times tables

• Multiplication and related division facts for the 4, 6, and 8 times tables. Children will also be taught the connection between the 2, 4 and 8 times tables through doubling and halving (so if 2 x 3 = 6 then 4 x 3 = 12 ) and the same for 3 and 6 times tables.
