Read and alter existing sequential code, and describe how changes affect outcomes
30 tutor-authored questions for this Ontario curriculum expectation, ordered easiest to hardest, every one with a full worked solution. Work through all 30 with your weekly-lesson access code.
Sample: the first question, solved
Given code "move up, move up," what happens if you change it to "move up, move up, move up, move up"?
📘 Worked solution
✓Instead of ending 2 steps up, the character now ends 4 steps up - two extra moves.
And one from the hard end
The code "move right, move right, move right, move left" was meant to move a character exactly 3 steps right with no backward movement, but it has a mistake. Identify the error, correct the code, and explain how you know the fix is right.
