Quick recap from Robots. Is each line about when, where or what?

Drag a card into a box. Or tap the card, then tap the box.

Hint

on: is when. runs-on: is where. Steps are what.

Predict

Try it

Now the quick test. Each right answer ticks a lesson you can skip. Not sure? Tap “I don’t know yet”. There is no timer.

Answer what you can. Skip what you don't know. No pressure.
