Computational thinking, coding & data literacy
Computational thinking
Break problems into parts, describe steps and conditions, then test the procedure with different examples.
How to learn
State the input and result
Write down the information you start with and the required result. Solve one example by hand.
Break it down
Split the task into smaller parts. Identify repeated work and the information each part needs.
Describe steps and conditions
Write instructions in ordinary language: what to do, when to branch, what repeats and when to stop.
Test ordinary and edge cases
Test a normal input, an empty input and a missing result. Then see whether fewer steps can produce the same correct answer.
