This Computing scheme of work video introduces the concept of algorithms and how they are used to build programs in Scratch. It supports teaching across Key Stage 1 and Key Stage 2 by explaining what algorithms are and how children can understand and apply them.

An algorithm is a step-by-step set of instructions used to complete a task—just like a recipe or directions through a maze. The video draws on everyday examples to help build children’s understanding, before linking these ideas to computing.

In the early years of the curriculum, pupils learn that algorithms are precise sets of steps that must be followed carefully. As they progress into Key Stage 2, they begin using logical reasoning to write, test and debug algorithms using coding tools like Scratch.

The video demonstrates how algorithms in Scratch are formed by connecting blocks together. For example:

• When green flag clicked starts the sequence

• Move, wait, and turn blocks each provide specific instructions

• Combined, these form a complete algorithm the sprite will follow exactly

This video is part of Kapow Primary’s Computing teacher programming resources. It supports teachers in making the concept of algorithms accessible and engaging, while laying the foundation for pupils to become confident coders.
