This week in Year 3, the children explored adding and subtracting ones across a ten using practical resources. Using counters, they were able to physically represent numbers and develop a deeper understanding of what happens when we cross a ten boundary.

The children worked methodically, carefully arranging their counters into groups of ten and ones. As they added and subtracted, they discovered when they needed to exchange ten ones for one ten, or one ten for ten ones. This hands-on approach helped them visualise the mathematics and build confidence in their understanding of place value.

There was a great sense of excitement as the children used exchanging to find the answers to increasingly challenging calculations. By moving the counters themselves, they could clearly see why numbers change when crossing a ten, making abstract concepts much more concrete.
