Unit F – Subtraction Changes
This maths scheme of work for Key Stage Two gets the children to develop and refine mental and informal written calculation skills when subtracting different pairs of three digit numbers and ones, tens and hundreds. The class can explain how to exchange between place value when completing the calculations.
