A list of instructions in order · A program is a set of steps arranged in the order they should happen.
Forward · The second step in the list is Forward, the same as the first.
True · Guessing first helps you check if the program does what you expected.
Forward · Counting from step 1, the third step in the list is Forward.
Predicting, then checking · She made a prediction, then ran the program to see if she was right.
False · You only need to find the one wrong step and fix it, not redo everything.
Forward, Forward, Turn left, Forward · The steps match Leo's plan in the same order he described it.
Step 3 · The first two steps worked, so the turn step is the one to check and fix.
