QCE Digital Solutions Unit 1: Desk checks and trace tables
Students check algorithmic steps by hand using dry runs and trace tables, and use them to find errors and state an algorithm's purpose.
One content description from the full QCE Digital Solutions Unit 1 — Programmed Solutions journey. All 12 modules below are in that journey too, with the same content — add just these to a class, or the whole strand.
