Question 1
A school collected 2,460 cans for recycling. The principal said, 'The digit 4 in our total represents 10 times what it would represent if it moved one place to the right.' If the digit 4 moved one place to the right, how many cans would the new total be?
- 2,064
- 2,406
- 2,046
Explanation: In 2,460, the digit 4 is in the hundreds place (value = 400). Moving it one place to the right puts it in the tens place (value = 40). The new number becomes 2,046, where the 4 represents 40 instead of 400. This confirms the relationship: 400 is 10 times 40. Choice A (2,064) puts 4 in the ones place. Choice B (2,406) rearranges digits incorrectly. Choice D (2,604) moves other digits around incorrectly.
Question 2
Emma wrote the equation 7,000÷70=100. Her teacher said this doesn't demonstrate the basic place value relationship. To fix it and show that a digit in one place represents 10 times what it represents in the place to its right, Emma should change her equation to:
- because this compares adjacent place values correctly
Question 3
In the number 58,347, Carlos multiplied the value of the 8 by a certain number and got 80,000. Then he divided the value of the 3 by that same number. What was his result?
Question 4
A digital scoreboard shows 45,630 points. Due to a malfunction, each digit shifts one place to the right, and a 0 appears in the ten-thousands place. What does the scoreboard show now, and how does this demonstrate place value relationships?
- 4,563 and each original digit now represents times its original value
Question 5
A factory produces widgets numbered with consecutive integers. The manager notices that widget #23,450 and widget #2,345 have the same digits. She wants to find the ratio between these numbers to demonstrate place value concepts to her workers. Which explanation should she give?
- The ratio is 21,105 because that's the difference between the widget numbers
Question 6
Study this pattern: 50÷5=10, 500÷50=10, . Based on place value understanding, what should come next in this pattern?
Question 7
Look at this pattern: 9×1=9, 9×10=90, . Based on place value relationships, which statement explains why equals ?
Question 8
Chen compares 700 and 70. Which statement correctly describes the relationship between them?
- 700 is 100 times 70.
- is 10 times .
Question 9
In the number 2,222, the digit 2 in the tens place represents what value compared to the digit 2 in the ones place?
- It is 2 times as much.
- It is the same value.
- It is 100 times as much.
- It is 10 times as much.
Explanation: This question tests 4th grade understanding that in a multi-digit whole number, a digit in one place represents ten times what it represents in the place to its right (CCSS.4.NBT.1). Our place value system is based on groups of 10. Each place value position is 10 times the position to its right—ones become tens (×10), tens become hundreds (×10), hundreds become thousands (×10). This means that the same digit in adjacent places has values that differ by a factor of 10. For example, 7 in the hundreds place (700) is 10 times the 7 in the tens place (70). In the number 2,222, the digit 2 appears in the tens place (value 20) and the ones place (value 2), requiring students to recognize that 20 is 10 times 2. Choice A is correct because calculating that 20 is 10 times 2 demonstrates understanding that adjacent place values have a 10-to-1 relationship. Choice B represents using 100 instead of 10 (confused with non-adjacent places), which happens when students don't understand multiplicative relationships between places. To help students: Use place value charts or base-ten blocks to show that 1 hundred = 10 tens, 1 thousand = 10 hundreds. Emphasize the pattern: moving one place to the left multiplies by 10, moving one place to the right divides by 10. Practice with division: 700 ÷ 70 = 10, 5,000 ÷ 500 = 10, 30 ÷ 3 = 10 (always 10 for adjacent places). Use numbers with repeating digits (4,440, 7,777) to make the relationship clear. Point out that the DIGIT stays the same, but the VALUE changes by 10 times. Watch for: students who subtract instead of divide, students who use 100 for the relationship (that's for places two positions apart), and students who give the digit value instead of the multiplicative relationship.
Question 10
In the number 6,600, the digit 6 in the thousands place represents how many times what the digit 6 in the hundreds place represents?
- 60
- 6
- 10
- 100

This means that the same digit in adjacent places has values that differ by a factor of 10. For example, 7 in the hundreds place (700) is 10 times the 7 in the tens place (70). In the number 6,600, the digit 6 appears in the thousands place (value 6,000) and the hundreds place (value 600), requiring students to recognize that 6,000 is 10 times 600. Choice B is correct because dividing the larger value by the smaller value: 6,000 ÷ 600 = 10, demonstrating understanding that adjacent place values have a 10-to-1 relationship. Choice D represents using 100 instead of 10 (confused with non-adjacent places), which happens when students confuse operations. To help students: Use place value charts or base-ten blocks to show that 1 hundred = 10 tens, 1 thousand = 10 hundreds. Emphasize the pattern: moving one place to the left multiplies by 10, moving one place to the right divides by 10.

Question 12
Based on the ten-times place value relationship, what is 70÷7?
- 10
- 100
- 63
- 0.1
Explanation: This question tests 4th grade understanding that in a multi-digit whole number, a digit in one place represents ten times what it represents in the place to its right (CCSS.4.NBT.1). Our place value system is based on groups of 10. Each place value position is 10 times the position to its right—ones become tens (×10), tens become hundreds (×10), hundreds become thousands (×10). This means that the same digit in adjacent places has values that differ by a factor of 10. For example, 7 in the hundreds place (700) is 10 times the 7 in the tens place (70). In this problem, students use place value to find 70 ÷ 7, where 70 (7 tens) and 7 (7 ones) require identifying the multiplicative relationship. Choice C is correct because dividing the larger value by the smaller value: 70 ÷ 7 = 10, recognizing that each place is 10 times the place to its right. Choice D represents using 100 instead of 10 (confused with non-adjacent places), which happens when students think about distance between places rather than value relationship. To help students: Use place value charts or base-ten blocks to show that 1 hundred = 10 tens, 1 thousand = 10 hundreds.
