representations, and mentally, including:
a two-digit number and ones
a two-digit number and tens
two two-digit numbers
adding three one-digit numbers
Count in steps of 2, 3, and 5 from 0, and in tens from any number,
forward and backward
Recall and use multiplication and division facts for the 2, 5 and 10
multiplication tables,
Recall and use addition and subtraction facts to 20 fluently, and
derive and use related facts up to 100
Year 3
Add and subtract numbers mentally, including:
a three-digit number and ones
a three-digit number and tens
a three-digit number and hundreds
Count from 0 in multiples of 4, 8, 50 and 100

Cromwell Academy --- Mental Maths
Multiply and divide mentally, including: multiplying by 0 and 1;
dividing by 1; multiplying together three numbers
Count from 0 in multiples of 4, 8, 50 and 100; find 10 or 100 more or
less than a given number
Use multiples of 2, 3, 4, 5, 8, 10, 50 and 100.
Extend known facts to three-digit numbers to derive facts, (for example
600 ÷ 3 = 200 can be derived from 2 x 3 = 6).
Year 5
Add and subtract numbers mentally with increasingly large numbers
Multiply and divide numbers mentally drawing upon known facts
Use increasingly large numbers to aid fluency (for example, 12 462 ---2300 = 10 162).
They mentally add and subtract tenths, and one-digit whole numbers
and tenths.
Year 6
Perform mental calculations, including with mixed operations and
