Practising our column subtraction outside 18.11.19
As the weather was so beautiful we decided to take our learning outside! Year 3 used the playground as a blank canvas and spent time developing their column subtraction skills. The children supported each other by taking it in turns to be the 'teacher' and explain strategies to one another. Some of us even began to look at 3 digit column subtraction and noticed that the process of exchanging 1 hundred for 10 tens is the same as exchanging 1 ten for 10 ones! Having a secure understanding of this concept will support the children in their learning across the mathematics curriculum.
