Ed's Computational Thinking Challenge

Explore. Plan. Test. Debug. Your teacher will lead the thinking โ€” you can experiment with Ed's language before committing to a full algorithm.

Level map locked

You are not ready to see the level yet. First, investigate Ed's language. Your teacher will unlock the map when the class is ready to plan.

Crack Ed's language

Investigation: Ed is extremely literal. An instruction that is nearly right is still wrong. Use evidence from your tests to discover the exact structure he understands.

Try different possible instructions. Put each idea on a new line, then test them together. Ed will only say whether he understands each instruction โ€” he will not reveal the correct wording.

Challenge: Change one part at a time. Can you work out the exact rule that successful instructions follow?

Ed is fussy. Test, compare and look for a pattern in the instructions he accepts.

The map and full algorithm box stay hidden until your teacher unlocks the next stage. Keep investigating Ed's language for now.

Your teacher controls when the class moves on. The map cannot be viewed before the level is unlocked.
