Unit E – Addition Exchange
This maths scheme of work for Key Stage Two gets the children to investigate different ways of adding three and four digit numbers using mental and formal written calculations with exchange between place value. The class can explain how to correctly use a written method of columnar addition to complete each calculation.
Investigate different ways of adding three and four digit numbers using mental and formal written calculations with exchange between place value
Lesson One : Changing Numbers
Investigate and record changes that can happen to a selection of four digit numbers when adding different sets of ones, tens, hundreds and thousands
Lesson Two : Grid Addition
Revise and model how to use the grid method to add different pairs of two digit numbers utilising partitioning between their sets of tens and ones
Lesson Three : Addition Number Sums
Explain and model how to add different pairs of three and four digit numbers with no exchange between place value when completing the calculations
Lesson Four : Sum Corrections
Practise adding different pairs of three and four digit numbers with one exchange between place value when completing each addition calculation
Lesson Five : Supermarket Stock
Identify and record how to calculate the stock levels of different products that can be sold in a supermarket by adding pairs of three and four digit numbers
