An average is a number that is calculated by adding amounts together and then dividing the total by the number of quantities.

In the Evolution and inheritance unit, they will build on this knowledge to learn that living things produce offspring of the same kind, but normally offspring vary and are not identical to their parents

In the New life unit, pupils learnt that animals, including humans, have offspring which grow into adults. In this Human development unit, they will build on this knowledge to describe the changes as humans develop to old age
