Grade 2 Skip Worksheet Answer Key: problems 1–5
Problem 1: Count by 5s
Add 5 each time: 20 + 5 = 25, 25 + 5 = 30, 30 + 5 = 35, and 35 + 5 = 40, which matches the last number.
Answer: 25, 30, 35.
Problem 2: Count by 10s
Add 10 each time. The tens digit goes up by 1.
40, 50, 60, 70, 80, 90.
Problem 3: Count by 100s
Add 100 each time. The hundreds digit goes up by 1.
200, 300, 400, 500, 600, 700.
Problem 4: Start at 135
Add 5 each time: 140 + 5 = 145, 145 + 5 = 150, 150 + 5 = 155.
Answer: 145, 150, 155.
Problem 5: Across a hundred
Add 10 each time. After 290 the number becomes 300, because 29 tens plus 1 ten is 30 tens.

Problem 7: Count back by 10s
Take away 10 each time. The tens digit goes down by 1.
Answer: 60, 50, 40.
Problem 8: Find the missing number
490 + 5 = 495, and 495 + 5 = 500, so the number between 490 and 500 is 495.

Problem 12: Flats of 100
Say 100, 200, 300, 400, 500 as you touch each flat.
Answer: 500.
Problem 13: Compare the numbers
Compare the hundreds first. If they match, compare the tens, then the ones.
- The hundreds are both 3. Tens: 5 is more than 2. \(352 > 325\)
- The hundreds are both 6. Tens: 1 is less than 8. \(618 < 681\)
- All three digits match. \(740 = 740\)
- The hundreds are both 5. Tens: 0 is less than 7. \(507 < 570\)
Problem 14: Compare the ones
When the hundreds and tens match, compare the ones.
- 7 ones is less than 9 ones. \(487 < 489\)
- 3 ones is more than 2 ones. \(213 > 212\)
- 5 ones is less than 6 ones. \(725 < 726\)
Problem 15: Compare with expanded form
Write each expanded form as a number first.
- \(300 + 20 + 5\) is 325. \(325 = 325\)
- \(500 + 6\) is 506. The tens: 0 is less than 6. \(506 < 560\)
- \(400 + 80 + 1\) is 481 and \(400 + 10 + 8\) is 418. Tens: 8 is more than 1. \(481 > 418\)

Answer: \(248 < 251\).
Problem 17: Points on a number line
Point A is at 420 and point B is at 450. B is farther right, so it is greater and A is less.
Answer: A = 420 and B = 450, and \(420 < 450\).
Problem 18: Sticker days
