Introduction |
---|
Children are introduced to the concept of mathematical coding through practical activity, transforming shapes on a grid. |
Episode 1: |
Children explore making shapes on a pin board, following a rule. They struggle to describe the transformed shapes in terms of both position and movement. They discuss how they recorded the moves and agree a two-part coding system. |
Episode 2: |
The class discuss a more complex transformation. Children work in pairs to explore how many possible shapes can be generated by the new move and apply the coding system to record their findings as they work. They discuss and identify a rule for the two-part move. |
Episode 3: |
Children predict the number of moves needed to create a range of given shapes and then test to find out. They give instructions for more complex transformations. Finally they look for patterns and make generalised statements. |
