Connor is writing down a simple algorithm. He writes down all the steps. The steps must be:

Computers need algorithms to work. They need to be told the steps to make things happen. An algorithm is like a list of instructions. But it’s not just computers that need instructions. We do, too. Which one of these everyday examples is an algorithm?

There is a big red square painted on the school playground. Mrs Smith is a teacher. She takes her class out to the playground. Mrs Smith gives instructions about how to walk once round the big red square. Mrs Smith asks Alice to stand at one corner of the big red square. Mrs Smith tells Alice to walk to the next corner of the square. She then tells Alice to turn right. What is Mrs Smith’s next instruction to Alice?
