Unit G – Two Digit Addition

This maths scheme of work for Key Stage One gets the children to model and record how to solve number problems involving addition of pairs of two digit numbers including exchange between place value. The class can explain how to use an expanded method of addition to add the tens and ones in pairs of numbers.

Model and record how to solve number problems involving addition of pairs of two digit numbers including exchange between place value
