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
Given code "move left, move left, move left," what happens if you change it to "move left, move left"?
📘 Worked solution
✓The character now ends 2 steps left instead of 3 — one fewer move.
And one from the hard end
If sequential code "move forward, spin, play sound" is changed to concurrent code "move forward AND spin AND play sound" (one combined step), how does the timing change?
