Key Concepts – Number –  Addition and subtraction

• That place value is a really important concept which supports all other areas of mathematics and is based on unitizing, treating a group of things as one ‘unit'.
• That when we add we are putting groups together, therefore making our number bigger.
• That when we subtract we are removing, therefore making our number smaller.
• That when we add and subtract we don’t always have to count 1 at a time.
• That we don’t always have to start at 0 when we count on.
• That there are different words for add and subtract, but they mean the same thing.
• That = can be at the start of a number sentence as well as the end.
• When counting along a number line we need to put our finger on the number we are starting with and as we count we move.

Common Misconceptions – Addition and subtraction

That when adding we start at a number and begin counting on from the next number. E.g. 4 + 3 we would count 1 jump as we reach 5, etc.

That when subtracting we start at a number and begin counting back from the next number. E.g. 8 – 2 we would count 1 jump as we reach 7.

The idea of counting past ten. That the next number is 11.

Common Misconception – Position and direction

The difference between right and left and strategies to learn these.

That turns can only start from one position. E.g. all facing the same direction and completing a ¼ turn
