10 tutor-authored questions for this Ontario curriculum expectation, ordered easiest to hardest — every one with a full worked solution. Work through them free, no account needed.
Sample: the first question, solved
"repeat 3 times: (repeat 2 times: move up)." What happens if you change the outer loop to "repeat 5 times"?
📘 Worked solution
✓Total move-up actions increases from 3×2=6 to 5×2=10.
And one from the hard end
A nested loop "repeat 2 times: (repeat 4 times: jump)" is rewritten as a single "repeat 8 times: jump." Are they equivalent?
