Recap and recall
Before starting this unit, check that the children can recall: Scratch is a block programming language. A loop is a coding tool used to repeat an instruction in a program. An algorithm is a series of instructions put in an exact order. Decomposition means breaking a problem into manageable chunks. Hand out the devices (one…

Adaptive teaching
Pupils needing extra support
Should complete the Activity: Catch the doughnut: support version to structure the process of understanding the blocks; could verbally explain each block’s purpose.
Pupils working at greater depth
Should explain how the variables and if statements work together to control the game; could consider where variables and if statements are used in real life (e.g. traffic lights, online quizzes, etc.).
