2nd Grade Skip Counting and Comparing Numbers Quiz: 10 Questions with Explanations

A \(30\)B \(45\)C \(35\)D \(37\)

The jumps count by 5s: 5, 10, 15, 20, 25, 30, 35. The mark is the seventh jump, which is 35.

A \(470\)B \(461\)C \(465\)D \(560\)

Counting by 10s adds 10 to the tens digit, so 460 + 10 = 470. Changing the hundreds digit means counting by 100s.

A \(210, 220\)B \(250, 300\)C \(300, 350\)D \(300, 400\)

Add 100 each time: 200, 300, 400, 500. The hundreds digit goes up by 1.

A 11 centsB 30 centsC 6 centsD 35 cents

Count by 5s six times: 5, 10, 15, 20, 25, 30. Adding 5 + 6 gives 11, which is a common mistake.

A \(< \)B \(=\)C \(+\)D \(>\)

Both have 6 hundreds. 4 tens is more than 2 tens, so 642 is greater than 624.

A \(236 > 263\)B \(236 < 263\)C \(236 = 263\)D \(263 < 236\)

The hundreds match. 3 tens is less than 6 tens, so 236 is less than 263.

A \(810\)B \(108\)C \(180\)D \(801\)

All four numbers use the digits 8, 1 and 0. 810 and 801 have 8 hundreds; 1 ten is more than 0 tens, so 810 is greatest.

A \(195, 159, 519\)B \(519, 195, 159\)C \(159, 195, 519\)D \(159, 519, 195\)

Compare hundreds first: 159 and 195 have 1 hundred and 519 has 5. Then 5 tens is less than 9 tens.

A \(95\)B \(100\)C \(105\)D \(115\)

90, 95, 100. Starting number counts as the first, so the third number is 100.

A \(520\)B \(510\)C \(530\)D \(502\)

500, 510, 520: the mark is two jumps after 500. Counting on by 1s would give 502.
