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.
Develop and refine mental and informal written calculation skills when subtracting different pairs of three digit numbers and ones, tens and hundred
Lesson One : Subtracting Hundreds
Practise using number facts and mental calculation techniques to record how to subtract different pairs of multiples of one hundred when completing number calculations
Lesson Two : Quick Subtraction
Explain and model how to use counting back to practise subtracting different pairs of three digit numbers and ones when completing subtraction number calculation
Lesson Three : Number Frames
Practise using concrete equipment and pictorial diagrams to model and record how to complete subtractions of ones from different three digit numbers
Lesson Four : Number Changes
Explore and record changes to the place value of digits in a three digit number when subtracting ones crossing tens for exchange
Lesson Five : Subtracting Tens
Practise subtracting different multiples of ten from a range of three digit numbers using an abacus to model each of the subtraction number calculations
