This week in Year 3 we have moved on from Place Value and began our next unit, Addition and Subtraction.

We have looked at patterns in adding multiples of 100; for instance, to solve 300 + 200 we can use 3 + 2 to help us.

We then began looking at adding and subtracting 3-digit numbers and ones. We noticed that when not crossing 10, only the ones digit will change.

This enabled most of us to work out these quite tricky fluency questions in our heads! Look at our fabulous work!
