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 — 200 gKA-0151Ratio as parts of a whole
- AI worked out the part size correctly and then answered for the sugar instead of the flour.
- BI split the 320 grams into two halves instead of into eight equal parts.
- DI took three fifths of 320 rather than five eighths, using the ratio numbers as a fraction of each other.
- EI divided 320 by the 5 in the ratio and stopped, treating 5 as the number of parts.
2.B — 76.80 poundsKA-0153Percentages and simple discounts
- AI assumed a 20 percent rise and a 20 percent fall must cancel because the percentages match.
- CI applied only the fall and forgot the rise.
- DI got the size of the change right but the direction wrong.
- EI applied only the rise and forgot the fall.
