Assignment Dry Run
This activity, available in three different programming languages, requires students to ‘dry run’ written code and work out what it does. This is a useful skill for programming, which tests their understanding of assignment and subsequent changes to variables within programs. They step through code and analyse the values assigned to variables at each step.
The challenges get steadily more complex, introducing a third variable and several re-assignments to trace.
The exercise would be well suited to students just starting to program in a text-based environment, or preparing to progress from programming in a visual environment.
