🥪 Giving Step-by-Step Instructions

What you’ll learn

1. What Is an Instruction?Understand that an instruction tells someone exactly what to do, and that good instructions are single, clear little jobs.An instruction is a clear direction to do one small job, like 'put on your shoes.' Breaking big jobs into small, clear instructions makes them easy to follow.
2. Step by Step, In OrderUnderstand that big tasks are sequences of steps and that the order of the steps matters.Many jobs are made of several steps that must be done in the right order, such as making a sandwich. Doing the steps out of order stops the job from working.
3. Oops! A Missing StepSee that leaving out a step causes the whole task to fail, especially for something that follows steps exactly.Skipping a step, like forgetting to open the jam jar, breaks the whole task. A computer or robot that follows steps literally will get stuck when a step is missing.
4. Say Exactly What You MeanUnderstand that instructions must be clear and exact rather than fuzzy or vague.Clear instructions say exactly what to do and to what, like 'put the cup on the table,' while fuzzy ones like 'put it over there' are hard to follow. Precision helps any follower, human or computer.
5. Computers Follow Directions TooUnderstand that computers follow instructions exactly and in order, and that a list of steps is a program with an algorithm inside.Computers and robots carry out instructions exactly and quickly but cannot guess intentions. A written list of steps is a program, and the ordered plan of steps is called an algorithm.
6. Fixing the StepsLearn that when steps go wrong you find and fix the broken step — a process called debugging.When a set of steps fails, you check each step in order to find the mistake, fix it, and try again. Finding and fixing errors in instructions is called debugging.
7. You're a Programmer!Connect clear, ordered, complete instructions to what programmers do, and spot sequences in everyday life.Giving clear steps in the right order, with none missing, is the heart of programming. Everyday routines like getting dressed or brushing teeth are sequences of steps, so children are already thinking like programmers.
