In this resource, pupils are tasked with solving a puzzle by coming up with an algorithm that their team can follow faster than anyone else.
This gives a way to introduce the idea of the solution to a problem being a set of instructions that allow others to ‘solve’ it with no understanding.
It also explores how different algorithms can solve the same problem but may not be equally good – some may be faster.
Children will learn about algorithms, computational thinking, testing and efficiency
