SC 1.1: Choosing the right thinking tool

This is the first page of the lesson. Read it and have a go at the activities. The rest is in the full lesson.

35 minutes

One problem, four tools

A tablet in the library will not connect. A technician breaks the problem into parts. They notice that two other tablets failed last week. They ignore the tablet's colour and keep the error code. They write a checklist for the next time.

That is computational thinking (solving problems in clear steps), with all four parts used together.

By the end of this lesson

Note

I can judge which parts of computational thinking suit a support or security problem.

The parts depend on each other

The four parts are not four separate jobs. Each one feeds the next.

Decomposition gives you small parts. Pattern recognition finds what the parts share. Abstraction removes what does not matter. Algorithmic design turns what is left into steps. The steps then show new parts or patterns, so you go round again.
