Year 4 have been exploring the place value counters and have used the place value mats to support them with addition and subtraction.
The children have really enjoyed being able to see larger four digit numbers partitioned. When adding, the children can visually see the number increasing.
We have taught the children to exchange ten ones for one ten when subtracting.
The children have now moved onto using column addition and column subtraction to solve more complex number problems. They are confident with using this method with four digit numbers because the place value counters have enabled them to visualise the process mentally.
