Maths - capacity greater and less than

We are two Primary teachers, each with 22 years experience, teaching from Early Years, Years 1,2,3,4,5, and 6, in addition to Senior Manager roles, in public and private schools. This has given us an in-depth knowledge of how children progress throughout their school life and a strong understanding of the whole learning process. Between us, we have also spent a number of years as whole school Leader of Reading & Writing and whole school Leader of Maths.
