Add and Subtract I can use materials or drawings to show how numbers fit together to 100. I can make organised lists showing the numbers that fit together to 100. I can add near doubles by thinking about doubles.

I can use basic facts to work out new facts (e. g I can use basic facts to work out new facts (e.g. 8+7 = 15 so 80+70 = 150 or 28+7=35). I can use a number line to show how I count on or back to add or subtract. I can break numbers into ones, tens and hundreds to add and subtract three digit numbers, I can think about addition to help me subtract (e.g. for 43-27, think ‘what do you have to add to 27 to get to 43’.

I can use a jump strategy to add or subtract through a ten or a hundred (e.g. 185+36 could be 185+15=200+21). I can count on or back in tens to help add or subtract (e.g. 28 + 37 = 28 + 30 + 7 = 58 + 7). I can add or subtract numbers close to 10 by adding or subtracting ten then Adjusting.

I can use materials or drawings to show the parts and the whole in a number story. I can skip count in 2s, 5s or 10s to help me add or subtract. . I can use a part-part-whole diagram to decide if I should add or subtract. I can use a part-part-whole diagram to help me write a number sentence.

I can use the constant key to skip count. I can accurately enter and read out numbers to 1000. I can use the add, subtract, multiply, divide, equals and constant keys.

I can add and subtract three digit whole numbers. multiples of 10 or 100 to or from numbers to 1000. I can demonstrate an understanding of the commutative law, for example 6 + 3 = 3 +6. I can solve two step problems and show my workings.
