NNAT Practice Pack — Grade 2

Answer Key — NNAT Grade 2

1. 1. C — Each row holds the same three figures, sliding two places every row — so every row and every column contains each figure exactly once. The empty corner's row and column are both missing the same figure: C. The others: A repeats the figure beside the empty cell; B the right figure with the wrong fill; D repeats the figure above the empty cell; E the right figure at the wrong size.
2. 2. C — Lay one design over the other: every mark from both appears once. That gives C. The others: A keeps only the second design; B invents a mark neither design has; D loses one mark in the merge; E keeps only the first design.
3. 3. A — Follow the pattern's rows and columns into the hole: the missing piece must continue them without a jump. A lines up exactly. The others don't: B shifted sideways off the pattern's rhythm; C the pattern at the wrong size; D the pattern too tightly packed; E the right patch turned a quarter-turn.
4. 4. C — In the top row, a smaller copy appears inside. Applying the same change to the bottom figure gives C. The others each make a specific mistake: A the bottom figure with no rule applied; B applies a different rule than the top row shows; D right change, wrong figure shape; E copies the top row's result instead of transforming the bottom figure.
5. 5. B — Each row holds the same three figures, sliding two places every row — so every row and every column contains each figure exactly once. The empty corner's row and column are both missing the same figure: B. The others: A repeats the figure beside the empty cell; C repeats the figure above the empty cell; D the right figure with the wrong fill; E the right figure at the wrong size.
6. 6. C — Lay one design over the other: every mark from both appears once. That gives C. The others: A loses one mark in the merge; B keeps only the second design; D keeps only the first design; E the merged design slid one place.
7. 7. E — Follow the pattern's rows and columns into the hole: the missing piece must continue them without a jump. E lines up exactly. The others don't: A the pattern at the wrong size; B the right patch turned a quarter-turn; C the right patch mirrored; D shifted sideways off the pattern's rhythm.
8. 8. E — In the top row, the figure's fill darkens one step. Applying the same change to the bottom figure gives E. The others each make a specific mistake: A copies the top row's result instead of transforming the bottom figure; B right change, wrong figure shape; C applies a different rule than the top row shows; D the bottom figure with no rule applied.
9. 9. B — Each row holds the same three figures, sliding two places every row — so every row and every column contains each figure exactly once. The empty corner's row and column are both missing the same figure: B. The others: A the right figure with the wrong fill; C repeats the figure above the empty cell; D the right figure at the wrong size; E repeats the figure beside the empty cell.
10. 10. A — Lay one design over the other: every mark from both appears once. That gives A. The others: B the merged design slid one place; C keeps only the first design; D loses one mark in the merge; E invents a mark neither design has.
11. 11. C — Follow the pattern's rows and columns into the hole: the missing piece must continue them without a jump. C lines up exactly. The others don't: A the pattern at the wrong size; B shifted sideways off the pattern's rhythm; D the right patch mirrored; E the pattern too tightly packed.
12. 12. B — In the top row, a smaller copy appears inside. Applying the same change to the bottom figure gives B. The others each make a specific mistake: A a look-alike that doesn't follow the rule; C applies a different rule than the top row shows; D the bottom figure with no rule applied; E right change, wrong figure shape.
13. 13. C — Each row holds the same three figures, sliding one place every row — so every row and every column contains each figure exactly once. The empty corner's row and column are both missing the same figure: C. The others: A repeats the figure above the empty cell; B the right figure with the wrong fill; D the right figure at the wrong size; E a figure that breaks the cycle.
14. 14. E — Lay one design over the other: every mark from both appears once. That gives E. The others: A the merged design slid one place; B keeps only the first design; C keeps only the second design; D invents a mark neither design has.
15. 15. A — Follow the pattern's rows and columns into the hole: the missing piece must continue them without a jump. A lines up exactly. The others don't: B the pattern at the wrong size; C the pattern too tightly packed; D shifted sideways off the pattern's rhythm; E the patch from the wrong place in the pattern.
16. 16. D — In the top row, the figure grows. Applying the same change to the bottom figure gives D. The others each make a specific mistake: A right change, wrong figure shape; B the bottom figure with no rule applied; C copies the top row's result instead of transforming the bottom figure; E applies a different rule than the top row shows.
17. 17. D — Each row holds the same three figures, sliding two places every row — so every row and every column contains each figure exactly once. The empty corner's row and column are both missing the same figure: D. The others: A repeats the figure beside the empty cell; B the right figure with the wrong fill; C the right figure at the wrong size; E repeats the figure above the empty cell.
18. 18. D — Lay one design over the other: every mark from both appears once. That gives D. The others: A loses one mark in the merge; B the merged design slid one place; C invents a mark neither design has; E keeps only the first design.
19. 19. D — Follow the pattern's rows and columns into the hole: the missing piece must continue them without a jump. D lines up exactly. The others don't: A the patch from the wrong place in the pattern; B the right patch turned a quarter-turn; C shifted sideways off the pattern's rhythm; E the right patch mirrored.
20. 20. B — In the top row, the figure doubles. 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 copies the top row's result instead of transforming the bottom figure; D the bottom figure with no rule applied; E right change, wrong figure shape.
