WISC-V Practice Pack — Grade 8

Answer Key — WISC-V Grade 8

1. 1. A — In the top row, the figure doubles and the figure grows. Applying the same change to the bottom figure gives A. The others each make a specific mistake: B applies a different rule than the top row shows; C copies the top row's result instead of transforming the bottom figure; D applies only one of the two changes; E right change, wrong figure shape.
2. 2. C — Each number is multiplied by 3. 108 × 3 = 324.
3. 3. A — The relationship is "what it grows or turns into." seed → plant, so cub → bear.
4. 4. B — Lay one design over the other: every mark from both appears once, and a mark both designs share appears once, not twice. That gives B. The others: A invents a mark neither design has; C the merged design slid one place; D keeps only the second design; E loses one mark in the merge.
5. 5. B — In the top row, the figure's fill darkens one step and a smaller copy appears inside. Applying the same change to the bottom figure gives B. The others each make a specific mistake: A applies the change twice; C applies a different rule than the top row shows; D applies only one of the two changes; E the bottom figure with no rule applied.
6. 6. C — These are square numbers: 2², 3², … Next is 6² = 36.
7. 7. A — The relationship is "what it grows or turns into." caterpillar → butterfly, so bud → flower.
8. 8. A — Lay one design over the other: every mark from both appears once. That gives A. The others: B invents a mark neither design has; C the merged design slid one place; D keeps only the second design; E loses one mark in the merge.
9. 9. E — In the top row, the figure's fill darkens one step and the figure shrinks. Applying the same change to the bottom figure gives E. The others each make a specific mistake: A applies the change twice; B right change, wrong figure shape; C the bottom figure with no rule applied; D applies only one of the two changes.
10. 10. B — Each number is multiplied by 2. 16 × 2 = 32.
11. 11. A — The relationship is "worker to their workplace." pilot → cockpit, so farmer → farm.
12. 12. A — Lay one design over the other: every mark from both appears once, and a mark both designs share appears once, not twice. That gives A. The others: B keeps only the first design; C invents a mark neither design has; D keeps only the marks the designs share; E the merged design slid one place.
13. 13. A — In the top row, a smaller copy appears inside and the figure's fill darkens one step. Applying the same change to the bottom figure gives A. The others each make a specific mistake: B copies the top row's result instead of transforming the bottom figure; C applies the change twice; D the bottom figure with no rule applied; E applies a different rule than the top row shows.
14. 14. D — The amount added grows by 1 each step. Adding 5 to 13 gives 18.
15. 15. A — The relationship is "worker to their workplace." baker → bakery, so librarian → library.
16. 16. E — Lay one design over the other: every mark from both appears once, and a mark both designs share appears once, not twice. That gives E. The others: A keeps only the second design; B the merged design slid one place; C keeps only the marks the designs share; D loses one mark in the merge.
17. 17. D — In the top row, the figure doubles and the figure's fill darkens one step. Applying the same change to the bottom figure gives D. The others each make a specific mistake: A copies the top row's result instead of transforming the bottom figure; B applies only one of the two changes; C the bottom figure with no rule applied; E applies the change twice.
18. 18. D — Each number is multiplied by 2. 16 × 2 = 32.
19. 19. C — The relationship is "part to its whole." leaf → plant, so string → guitar.
20. 20. B — Lay one design over the other: every mark from both appears once, and a mark both designs share appears once, not twice. That gives B. The others: A keeps only the marks the designs share; C invents a mark neither design has; D keeps only the second design; E loses one mark in the merge.
