Answer key — Math Kangaroo practice

Each wrong choice carries the thinking that produces it. When a student picks C, this is what they were doing.

1.B — BoKA-0092Ordering and ranking from clues
- AI gave the child who is first rather than the one who is second.
- CI placed Cal directly after Ana, reading ahead of Dee as meaning immediately ahead.
- DI built the order backwards from the last position instead of forwards from the first.
- EI assumed the clues left several orders open without checking that they chain into a single one.
2.B — 8KA-0100Working backwards
- AI undid the operations in the order they were written instead of in reverse order.
- CI gave the final answer back, assuming the three steps cancelled each other out.
- DI doubled the 11 and subtracted the 6 but forgot the final halving that undoes the doubling.
- EI undid only the halving and stopped there without touching the other two steps.
