CogAT Practice Pack — Grade 4

Answer Key — CogAT Grade 4

1. 1. E — A darkening sky means rain is coming, which worries hikers without raincoats. A clear or blue sky would not.
2. 2. C — Each number is doubled (×2). 6 × 2 = 12.
3. 3. D — The pattern subtracts 6 each time. 30 − 6 = 24.
4. 4. E — In the top row, the figure shrinks and a smaller copy appears inside. Applying the same change to the bottom figure gives E. The others each make a specific mistake: A right change, wrong figure shape; B copies the top row's result instead of transforming the bottom figure; C the bottom figure with no rule applied; D applies a different rule than the top row shows.
5. 5. E — Unfold the paper step by step, mirroring every hole across each crease in reverse order. 2 punches through 2 layers leaves 4 holes. The other sheets each draw a specific mistake: A treated the mirror as a slide — hole positions right, orientation never flips; B doubled the count without the on-crease merge; C unfolded correctly but flipped the whole sheet; D shows only the punched folded sheet — never unfolded the paper.
6. 6. A — All three have strings, and so does a banjo. Drum, trumpet, flute and whistle have no strings.
7. 7. A — Adding the two equations gives ● + ● = 33 + 3 = 36, so ● = 18. Then ■ = 33 − 18 = 15. The question asks for ● = 18.
8. 8. B — What the three figures share: every figure has a dot above it. B shares it too. The others don't: A repeats an exemplar's shape but breaks the shared property; C no dot above it; D solid black instead of the shared property; E the dot sits below instead of above.
9. 9. D — The relationship is "action to its opposite." sit → stand, so throw → catch.
10. 10. B — Weeks of practice make someone feel confident. Playing or forgetting would not build confidence.
11. 11. C — Each number is doubled (×2). 9 × 2 = 18.
12. 12. D — The pattern subtracts 7 each time. 21 − 7 = 14.
13. 13. B — In the top row, the figure's fill darkens one step and the figure grows. Applying the same change to the bottom figure gives B. The others each make a specific mistake: A applies a different rule than the top row shows; C the bottom figure with no rule applied; D applies only one of the two changes; E right change, wrong figure shape.
14. 14. C — Unfold the paper step by step, mirroring every hole across each crease in reverse order. 3 punches through 4 layers leaves 12 holes. The other sheets each draw a specific mistake: A one hole drifted off its mirrored position; B shows only the punched folded sheet — never unfolded the paper; D treated the mirror as a slide — hole positions right, orientation never flips; E doubled the count without the on-crease merge.
15. 15. E — All three measure how long something is, and so does a mile. Pound measures weight, cup measures liquid, hour measures time, penny is money.
16. 16. B — First find ▲: 6 × 5 = 30. Then ? = 30 − 5 = 25.
17. 17. A — What the three figures share: all figures are small. A shares it too. The others don't: B does not share the property; C repeats an exemplar's shape but breaks the shared property; D too large; E does not share the property.
18. 18. B — The relationship is "what it grows or turns into." tadpole → frog, so egg → chick.
19. 19. A — A puppy that cannot sit still (restless) chews things, and toys give it something else to chew. A sleepy or quiet puppy would not chew everything.
20. 20. B — Each number is halved (÷2). 6 ÷ 2 = 3.
