NNAT Practice Pack — Grade 4

Answer Key — NNAT Grade 4

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