Differentiation

Pupils needing extra support: During the AfL (Assessment for Learning) activity, reduce the number of block possibilities. Focus on one character at a time, sit with an adult who can replay the original each time for them to focus on just that one character.

Pupils working at greater depth: Encourage them to take the algorithm and structure of the first little pig and apply it more independently to the second pig (sticks house).
