Algorithms Are Instructions
Year 1 learn that an algorithm is a clear set of ordered instructions, with fun unplugged activities.
# Algorithms Are Instructions
An algorithm is a special word for a set of step by step instructions that finish a task. The word sounds tricky, but the idea is simple. If you have ever followed a recipe or given someone directions, you have already used an algorithm.
Why Algorithms Matter
Algorithms help us solve problems in a careful order. When the steps are in the right order, the task works. When a step is missed or in the wrong place, the task goes wrong. Programmers use algorithms to plan their code before they type it into a computer.
Algorithms in Daily Life
Think about getting dressed. A sensible algorithm might be pants first, then a t-shirt, then socks and shoes. If you put shoes on before socks, the algorithm has a problem. Spotting the right order is an important skill.
Practise With a Picture
Draw a simple monster on paper without showing anyone. Now write instructions so a friend can draw the same monster, such as draw a big circle, add two eyes on top, give it three legs. Compare the pictures. This shows how clear your algorithm was.
What Makes a Good Algorithm
A good algorithm has clear steps, the right order and an end point. It tells you exactly what to do and when to stop. Learning to write good algorithms now will make real coding much easier later on.
