This feature for Primary teachers focuses on the concept of equivalence and showcases our balance interactivity in several guises. The tasks included aim to build on children's practical experiences of balances, using this as a context in which to discuss equality, and leading into considering ways we represent equivalence mathematically.

You can watch a recording of the webinar in which we discussed the mathematical thinking which can be prompted by these problems.
