Grade 2 Skip Test Answer Key: questions 1–5
Question 1: Fill in the numbers (3 points)
- Count by 5s: 315 and 325
- Count by 10s: 600 and 620
- Count by 100s: 450 and 550
Scoring: 1 point for each part; both blanks in a part must be correct.
Question 2: Count the coins (2 points)
- Count by 5s eight times : 5, 10, 15, 20, 25, 30, 35, 40. 40 cents
- Count by 10s twelve times : 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120. 120 cents
Scoring: 1 point for each correct value with cents.
Question 3: Compare the numbers (2 points)
- The hundreds are both 6. Tens: 4 is less than 7. \(647 < 674\)
- \(300 + 80 + 1\) is 381. \(381 = 381\)
Scoring: 1 point for each correct symbol.
Question 4: Compare the blocks (2 points)
- \(325 > 319\)
- The hundreds are both 3, so the tens place decides: 2 tens is more than 1 ten.
Scoring: 1 point for the correct symbol, 1 point for naming the tens place.
Question 5: Points on a number line (2 points)
- Point A is at 430 and point B is at 470.
- B is farther right. \(430 < 470\)
Scoring: 1 point for both numbers correct, 1 point for a correct comparison (accept 470 > 430).
Grade 2 Skip Test Answer Key: questions 6–9
Question 6: Crayon boxes (3 points)
- Count by 100s seven times : 100, 200, 300, 400, 500, 600, 700. 700 crayons
- 7 + 3 = 10 boxes. Keep counting: 800, 900, 1,000. 1,000 crayons
- The hundreds: 7 is more than 6. \(700 > 650\)
Scoring: 1 point for each part. In part b, accept 1,000 from any correct counting method.
Question 7: Find the mistake (2 points)
After 145, she jumped by 10 to reach 155. She skipped 150.
Counting by 5s the correct way: 135, 140, 145, 150, 155.
Scoring: 1 point for finding the mistake (150 is missing or she added 10); 1 point for the correct list.
Question 8: Which is greater? (2 points)
Both numbers have 4 hundreds. The tens digits are 8 and 9, and 9 tens is more than 8 tens.
\(498 > 489\), so 498 is greater.
Scoring: 1 point for 498 as the greater number; 1 point for comparing the tens digits.
Question 9: Missing digit (2 points)
The hundreds are both 6, so the tens digit must be small enough. Try 5: 654 is more than 651, so 5 does not work. Try 4: 644 is less than 651, so 4 works.
Answer: 4.
Scoring: 1 point for a correct reason that uses the tens place; 1 point for the digit 4.
