NNAT Practice Pack — Grade 7

Answer Key — NNAT Grade 7

1. 1. D — 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: D. The others: A the right figure at the wrong size; B a figure that breaks the cycle; C repeats the figure beside the empty cell; E the right figure with the wrong fill.
2. 2. 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 marks the designs share; B keeps only the first design; C the merged design slid one place; D loses one mark in the merge.
3. 3. 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 the pattern too tightly packed; E shifted sideways off the pattern's rhythm.
4. 4. C — In the top row, the figure's fill darkens one step and the figure doubles. Applying the same change to the bottom figure gives C. The others each make a specific mistake: A copies the top row's result instead of transforming the bottom figure; B the bottom figure with no rule applied; D applies only one of the two changes; E right change, wrong figure shape.
5. 5. 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 the right figure at the wrong size; B repeats the figure above the empty cell; C repeats the figure beside the empty cell; E the right figure with the wrong fill.
6. 6. 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 loses one mark in the merge; C the merged design slid one place; D keeps only the first design; E keeps only the marks the designs share.
7. 7. 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 patch from the wrong place in the pattern; B the right patch turned a quarter-turn; D the right patch mirrored; E the pattern too tightly packed.
8. 8. A — In the top row, the figure doubles 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 applies only one of the two changes; C right change, wrong figure shape; D applies the change twice; E copies the top row's result instead of transforming the bottom figure.
9. 9. A — 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: A. The others: B the right figure at the wrong size; C repeats the figure beside the empty cell; D the right figure with the wrong fill; E repeats the figure above the empty cell.
10. 10. 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 the merged design slid one place; B keeps only the first design; C keeps only the marks the designs share; D keeps only the second design.
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 right patch mirrored; B shifted sideways off the pattern's rhythm; D the patch from the wrong place in the pattern; E the right patch turned a quarter-turn.
12. 12. A — In the top row, the figure grows 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 applies the change twice; C the bottom figure with no rule applied; D applies a different rule than the top row shows; E copies the top row's result instead of transforming the bottom figure.
13. 13. A — 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: A. The others: B repeats the figure beside the empty cell; C the right figure at the wrong size; D repeats the figure above the empty cell; E the right figure with the wrong fill.
14. 14. D — Lay one design over the other: every mark from both appears once, and a mark both designs share appears once, not twice. That gives D. The others: A keeps only the marks the designs share; B invents a mark neither design has; C the merged design slid one place; E keeps only the second design.
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 right patch turned a quarter-turn; C the patch from the wrong place in the pattern; D the right patch mirrored; E shifted sideways off the pattern's rhythm.
16. 16. A — In the top row, the figure shrinks and a smaller copy appears inside. 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 the bottom figure with no rule applied; D applies only one of the two changes; E copies the top row's result instead of transforming the bottom figure.
17. 17. 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 the right figure at the wrong size; B the right figure with the wrong fill; D a figure that breaks the cycle; E repeats the figure beside the empty cell.
18. 18. A — Lay one design over the other: every mark from both appears once. That gives A. The others: B keeps only the second design; C the merged design slid one place; D loses one mark in the merge; E keeps only the first design.
19. 19. 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 patch from the wrong place in the pattern; B shifted sideways off the pattern's rhythm; C the pattern at the wrong size; D the right patch turned a quarter-turn.
20. 20. A — In the top row, the figure grows 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 applies the change twice; C applies a different rule than the top row shows; D right change, wrong figure shape; E applies only one of the two changes.
