Overcoming barriers in mathematics –

Derive and recall all pairs of numbers with a total of 10 and addition facts for totals to at least 5; work out the corresponding subtraction facts

Derive and recall all addition and subtraction facts for each number to at least 10, all pairs with totals to 20 and all pairs of multiples of 10 with totals up to 100

Count on and back in ones, twos, fives and tens and use this knowledge to derive the multiples of 2, 5 and 10 to the tenth multiple

Derive and recall multiplication facts for the 2, 5 and 10 times-tables and the related division facts; recognise multiples of 2, 5 and 10

Recall the doubles of all numbers to at least 10

Understand that halving is the inverse of doubling and derive and recall doubles of all numbers to 20, and the corresponding halves

Use knowledge of number facts and operations to estimate and check answers to calculations
