How it works
A computer does exactly what the steps say. It cannot guess what we mean.
So we give clear steps, one at a time, in the right order.
If the steps are mixed up, we get a funny result.
Worked examples
Not clear enough
- Nia says, put jam on the bread.
- Bo puts the whole jam jar on it, lid and all.
- A computer does exactly what we say, so we say it more clearly.
The wrong order
- Jam before bread.
- Splat! The jam lands on the table.
- The order of the steps matters.
Clear steps in order
- Get two slices of bread.
- Open the jar, and spread the jam with the spoon.
- Put the slices together, and Bo has made a sandwich.
Snack robot at home
- Make a snack with a grown-up, like fruit on a plate.
- Take turns being the robot, who does exactly what the steps say.
- If a step is not clear, that is a bug. Fix it together.
