1st Grade Comparing Two-Digit Numbers Quiz: 10 Questions with Explanations

A \(32 > 23\)B \(23 = 32\)C \(23 < 32\)D \(23 > 32\)

23 has 2 tens and 32 has 3 tens, so 23 is less than 32. Looking at the ones first leads to mistakes.

A \(59\)B \(16\)C \(67\)D \(60\)

67 has the same tens as 61 but more ones. The others have fewer tens or fewer ones.

A \(24 < 30\)B \(30 = 24\)C \(24 > 30\)D \(30 > 24\)

30 is 3 tens and 24 is 2 tens, so 30 is greater. The 4 ones in 24 do not matter.

A \(41\)B \(38\)C \(40\)D \(49\)

38 has 3 tens, which is less than 4 tens. 40 is equal to 40, not less.

A \(49 < 52\)B \(52 > 49\)C \(52 = 25\)D \(25 > 52\)

52 has 5 tens and 49 has 4 tens. 5 tens is more.

A \(22, 29, 92\)B \(29, 22, 92\)C \(92, 29, 22\)D \(22, 92, 29\)

22 and 29 have 2 tens and 22 has fewer ones. 92 has the most tens.

A \(76 > 71\)B \(71 = 76\)C \(76 = 71\)D \(71 < 76\)

76 is farther to the right, so 76 is greater and 71 is less.

A 3B 2C 5D 9

The tens match, so the ones must be less than 3. Only 2 works here. With 3 the numbers are equal.

A Noah, because \(44 > 40\)B Aisha, because \(40 > 44\)C They have the same numberD Aisha, because 0 ones is more than 4 ones

Both have 4 tens. Noah has 4 ones and Aisha has 0 ones, so Noah has more.

A The tens, because 8 is more than 7B The ones, because 9 is more than 3C The ones, because 3 is less than 9D Neither, the numbers are equal

The tens are different, so they decide. 83 is greater than 79 even though 9 ones is more than 3 ones.
