Three-Digit Place Value — Answer Key
Part A: Multiple Choice
Circle the best answer for each question.
1. Which symbol makes this true: 234 ___ 324?
A) <
B) >
C) =
D) +
234 has 2 hundreds and 324 has 3 hundreds, so 234 is less than 324.
2. Which number is greater than 569?
A) 498
B) 561
C) 570
D) 509
570 has the same hundreds as 569 but a larger tens or ones total, so 570 > 569.
3. Which statement is true?
A) 412 > 421
B) 412 = 421
C) 412 < 421
D) 421 < 412
Both have 4 hundreds, but 412 has 1 ten and 421 has 2 tens, so 412 is less than 421.
4. Which set of numbers is ordered from least to greatest?
A) 305, 350, 503
B) 503, 350, 305
C) 350, 305, 503
D) 305, 503, 350
305 has 3 hundreds, 350 has 3 hundreds and more tens, and 503 has 5 hundreds, giving 305 < 350 < 503.
Part B: Fill in the Blank
Write the correct answer on each line.
1. Compare: 628 < 682 using <, >, or =.
628 has 2 tens and 682 has 8 tens, so 628 is less than 682.
2. Compare: 745 = 745 using <, >, or =.
Every digit is the same in both numbers, so 745 equals 745.
3. Compare: 903 > 309 using <, >, or =.
903 has 9 hundreds while 309 has only 3 hundreds, so 903 is greater.
4. The smallest of 412, 142, and 421 is 142.
142 has 1 hundred, while 412 and 421 have 4 hundreds, making 142 the smallest.
5. The largest of 560, 506, and 650 is 650.
650 has 6 hundreds, which is more than 5 hundreds in 560 and 506.
