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.C — 16KA-0050Working backwards
- AI added the 4 and the 6 and stopped, forgetting to undo the halving.
- BI doubled the 6 first and then added the 4, reversing the steps in the wrong order.
- DI doubled the total at the end rather than doubling only the amount left after the first spend.
- EI doubled twice because spending half felt like it needed undoing more than once.
2.E — Not all birds can flyKA-0146Reading a logical statement precisely
- AI read some cannot as meaning none can, which is a far stronger claim.
- BI chose a statement that directly contradicts the one I was given.
- CI read some as meaning a majority, when it only guarantees at least one.
- DI read some as meaning exactly one, when it means at least one.
