Year 4 – adding and subtracting two 4-digit numbers

This week in Maths, year 4 have been learning to add and subtract two 4-digit numbers. Working with our talk partners we first practised making four digit numbers using our place value mats and 1000s, 100s, 10s and 1s counters. We then used the counters to add and subtract numbers looking at how the numbers columns change – particularly when we have to exchange numbers in a calculation.
