OLSAT Practice Pack — Grade 3

Answer Key — OLSAT Grade 3

1. 1. A — Losing a favorite toy makes you sad. Finding it would not make you sad.
2. 2. A — The relationship is "what it grows or turns into." puppy → dog, so tadpole → frog.
3. 3. C — Four of the five words are alike: they are odd numbers. two does not fit that group.
4. 4. D — Four of the five figures share one property: all figures are the same shape. D is the one that does not belong (solid black instead of the shared property).
5. 5. 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 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; E applies a different rule than the top row shows.
6. 6. 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 right change, wrong figure shape; B the bottom figure with no rule applied; D applies a different rule than the top row shows; E a look-alike that doesn't follow the rule.
7. 7. C — Each step, one more shape appears each time. Continuing one more step gives C. The others: A steps backward in the series; B repeats the last figure instead of stepping on; D the right figure with the wrong fill; E the right step on the wrong shape.
8. 8. A — The pattern subtracts 6 each time. 25 − 6 = 19.
9. 9. A — In every group each number is 7 more than the one before it. Applying the same rule to the last group gives 20: A.
10. 10. D — Across each row the numbers are multiplied by 2, and down each column they change by 6. The empty space must fit both its row and its column, which gives 812: D.
11. 11. B — Melting ice cream drips down your hand.
12. 12. C — The relationship is "animal to the sound it makes." bird → chirp, so bee → buzz.
13. 13. E — Four of the five words are alike: they are even numbers. five does not fit that group.
14. 14. A — Four of the five figures share one property: all figures are the same shape AND the same fill (only the size and the dot vary). A is the one that does not belong (the same fill, but a different shape).
15. 15. D — In the top row, 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 the change twice; C right change, wrong figure shape; E the bottom figure with no rule applied.
16. 16. E — In the top row, the figure grows. Applying the same change to the bottom figure gives E. The others each make a specific mistake: A the bottom figure with no rule applied; B a look-alike that doesn't follow the rule; C applies a different rule than the top row shows; D copies the top row's result instead of transforming the bottom figure.
17. 17. B — Each step, the figure alternates big and small. Continuing one more step gives B. The others: A the right step on the wrong shape; C does not continue the series; D jumps two steps ahead; E the right figure with the wrong fill.
18. 18. D — The pattern adds 7 each time. 23 + 7 = 30.
19. 19. E — In every group the second number is 3 times the first, and the third is 4 less than the second. Applying the same rule to the last group gives 3: E.
20. 20. E — Across each row the numbers change by -4, and down each column they change by 6. The empty space must fit both its row and its column, which gives 8: E.
