Computer lesson 27: Block coding basics · Set 351 · 40 questions

Remember (Times × amount): Event = when something happens; motion = move or turn; sound = play a sound; if = check a condition. A loop repeats the blocks inside it: total = times × amount. repeat N times [move, turn 360 ÷ N degrees] draws a shape with N sides.
