ACARA 9-10 Digital Technologies: Iteration with logical operators
Students write and draw FOR, WHILE and REPEAT loops with compound exit conditions, then combine loops with selection, counting and sequence in one algorithm.
One content description (AC9TDI10P05) from the full ACARA Digital Technologies Years 9–10 — Algorithms with Logical Operators journey. All 18 modules below are in that journey too, with the same content — add just these to a class, or the whole strand.
