This unplugged activity, from the CS4FN team at Queen Mary University of London, helps learners to understand variable assignment and operations. They use the idea of variables as boxes as the basis of a group activity, developing their use of logical thinking to trace variables through programs.
The activity seeks to undo misconceptions relating to variables, and demystifies why the assignment operator is not an ‘equals’ sign in computer programming. Practice ‘dry-running’ code is then provided, to help consolidate skills and understanding.
