Year 3 Computing – What Is an Algorithm?

A fun and accessible 2-lesson introduction to algorithms for Year 3 pupils.

This ready-to-use computing resource introduces children to the idea of an algorithm and helps them understand that an algorithm is simply a clear, ordered set of instructions used to complete a task or solve a problem.

Across two engaging lessons, pupils learn how algorithms work through familiar, age-appropriate examples before developing their ability to follow, order and create their own sets of instructions.

The activities help children understand:

What an algorithm is
Why instructions need to be clear and precise
Why the order of instructions matters
How to follow an algorithm step by step
How to identify mistakes in a sequence of instructions
How to create simple algorithms of their own

Designed specifically for Year 3 / Key Stage 2, the lessons use straightforward language and practical activities, making them particularly suitable for non-specialist computing teachers.

The resource supports the English National Curriculum for Computing, developing children’s understanding of algorithms and logical thinking.

Perfect for: Year 3 computing lessons, ICT lessons, classroom activities, independent work, assessment and computing schemes of work.
