Students fix three sentences with place value errors: rewriting 302,560 in correct expanded form, identifying that the 1 in 4,710,385 is in the ten-thousands place, and untangling a transposed standard form. Part B asks for the missing piece of 815,003 in expanded form, the place of 9 in 6,209,140, and the value of the 5 in 953,281.
Two short-answer prompts push deeper thinking — explaining why some place values vanish from the expanded form of 1,306,020 and what happens when the digit 8 jumps from hundreds to ten-thousands. Each correction trains fourth graders to count positions carefully before naming a place.

Place Value and Rounding
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
The expanded form of 302,560 is 300,000 + 20,000 + 560.
Rewrite: The expanded form of 302,560 is 300,000 + 2,000 + 500 + 60.
2. Fix the sentence:
In the number 4,710,385, the digit 1 is in the thousands place.
Rewrite: In the number 4,710,385, the digit 1 is in the ten-thousands place.
3. Fix the sentence:
500,000 + 60,000 + 3,000 + 200 + 10 + 4 equals 536,214 in standard form.
Rewrite: 500,000 + 60,000 + 3,000 + 200 + 10 + 4 equals 563,214 in standard form.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. The expanded form of 815,003 is 800,000 + 15,000 + 3
2. In 6,209,140, the digit 9 is in the thousands place.
3. The standard form of 2,000,000 + 400,000 + 70,000 + 600 + 5 is 2,470,605
4. In 953,281, the value of the digit 5 is 50,000
Part C: Short Answer
Answer each question in one or two complete sentences.
1. Write the number 1,306,020 in expanded form and explain why some place values are missing.
1,000,000 + 300,000 + 6,000 + 20. The ten-thousands, hundreds, and ones places have a digit of 0, so they do not appear in expanded form.
2. If you move the digit 8 from the hundreds place to the ten-thousands place, how does its value change?
The value changes from 800 to 80,000. Moving a digit one place to the left multiplies its value by 10, so moving it two places multiplies by 100.
