National curriculum

Attention grabber

Main event

Differentiation

Pupils needing extra support: Reduce the number of sprites they’re working with. Focus on one loop such as ‘repeat forever’.

 

Pupils working at greater depth: Add visual effects to how a sprite looks when it’s playing, so we know which have and haven’t been clicked.
