Why must the digits line up exactly? This 20-slide interactive lesson teaches adding and subtracting 4-digit numbers with no exchange, building the column method one careful step at a time.

Mastering Adding and Subtracting 4-Digit Numbers in Year 4 Maths

Pupils add and subtract up to two 4-digit numbers with no exchange, use place value alongside formal methods, and understand the importance of lining up digits correctly. They work through examples such as 9,623 + 145 = 9,768, always starting from the left-hand place value column, then use counters and a place value chart to work out calculations such as 3,124 + 2,325, and find missing numbers in partly completed additions such as 5,460 + 3,132 = 8,592.
