Show on a big screenA shop keeps 12 numbered cards in a row. To find one card, you look at cards one by one. How many looks will it take?
This track is Computational Thinking II.
What you will learn
- Count the looks. How many steps a search really takes.
- Look at the middle. Ignore half the cards at once.
- Read a flowchart. A plan drawn with ovals, boxes and diamonds.
- Draw one. Give every case an answer. A case is one way things can turn out.
- Mend one. Predict, run, compare. Find the bug, a mistake.
