Implementation
Our pupils should be able to organise their knowledge, skills and understanding around the following learning hooks:

Know and use numbers

Add and subtract

Multiply and divide

Use fractions

Understand the properties of shapes

Describe position, direction and movement

Use measures

Use statistics

Use algebra
These key concepts or as we like to explain them to children – learning hooks, underpin learning in each milestone. This enables pupils to reinforce and build upon prior learning, make connections and develop subject specific language.
