Math - Grade 2-3

Instructions: Read each question carefully. Circle the correct answer. For "select all that apply" questions, circle every correct answer. For written response questions, write your answer on the lines provided.
  1. 1

    What is the value of the digit 4 in the number 643? A) 4 B) 40 C) 400 D) 4,000

    B) 40. The digit 4 is in the tens place, so its value is 4 tens = 40.
  2. 2

    Order the following numbers from least to greatest. 512, 521, 498, 507 Write them on the lines: _______, _______, _______, _______

    498, 507, 512, 521. Compare the hundreds digit first: 498 has 4 hundreds while the rest have 5 hundreds, so 498 is smallest. Then compare the tens digits of 507, 512, and 521.
  3. 3

    How do you write 753 in expanded form? a) 700 + 53 b) 700 + 50 + 3 c) 750 + 30 d) 700 + 5 + 3

    b) 700 + 50 + 3. The 7 is in the hundreds place (700), the 5 is in the tens place (50), and the 3 is in the ones place (3).
  4. 4

    How do you write 480 in word form? a) Four hundred eight b) Four hundred eighty c) Four hundred eight zero d) Four hundred eighteen

    b) Four hundred eighty. The number 480 has 4 hundreds and 8 tens, which is read as four hundred eighty.
  5. 5

    How can the number 425 be expressed? Select all that apply. a) 4 hundreds + 2 tens + 5 ones b) 42 tens + 5 ones c) 4 hundreds + 25 tens d) 425 tens

    a) and b) are both correct. 4 hundreds + 2 tens + 5 ones = 425. Also 42 tens + 5 ones = 420 + 5 = 425. Option c) = 650 and option d) = 4,250, both incorrect.
  6. 6

    Which symbol makes this statement true? 347 _____ 374 a) > b) < c) = d) +

    b) < because 347 is less than 374. Both numbers have 3 hundreds, but 347 has only 4 tens while 374 has 7 tens.
  7. 7

    Fill out the chart to show 10 more, 10 less, 100 more, and 100 less for each number. | 10 less | Number | 10 more | 100 less | 100 more | |---------|--------|---------|----------|----------| | | 347 | | | | | | 215 | | | | | | 508 | | | |

    Row 1 (347): 337 | 357 | 247 | 447. Row 2 (215): 205 | 225 | 115 | 315. Row 3 (508): 498 | 518 | 408 | 608.
