4th Grade Place Value to One Million Quiz: 10 Questions with Explanations

A \(700\)B \(70\)C \(7\)D \(7{,}000\)

The digits of 6,075 are 6 thousands, 0 hundreds, 7 tens, and 5 ones, so the 7 is worth 70. Choosing 700 or 7,000 mixes up the places.

A 6B 5C 0D 8

Read the chart from the left: hundred thousands is 5, ten thousands is 6. Students often pick the first digit of the number.

A 10B 1,000C 100D 30

3,000 is 100 times 30 because each step left is ten times, and there are two steps from tens to thousands. Counting one step gives 10.

A \(7{,}000 + 300 + 5\)B \(7{,}000 + 30 + 5\)C \(700 + 300 + 5\)D \(7{,}000 + 300 + 50\)

7,305 has 7 thousands, 3 hundreds, 0 tens, and 5 ones. The tens place is 0, so there is no tens term.

A eight thousand, sixteenB eighty thousand, sixteenC eighty thousand, sixtyD eight hundred thousand, sixteen

80,016 is 80 thousand and 16. Check that the thousands period is 80 and the ones period is 16.

A \(450{,}000\)B \(45{,}000\)C \(540{,}000\)D \(400{,}500\)

Each tick is 100,000. Point P is halfway between 400,000 and 500,000, so it is 450,000.

A \(206{,}415 < 206{,}145\)B \(206{,}415 = 206{,}145\)C \(206{,}415 > 206{,}145\)D \(206{,}145 > 206{,}415\)

The numbers match through the thousands place. In the hundreds place, 4 is greater than 1, so 206,415 > 206,145. Choosing < reverses the order.

A \(6{,}000\)B \(66{,}000\)C \(60{,}010\)D \(600{,}000\)

Multiplying by 10 moves each digit one place to the left: 60,000 becomes 600,000. Moving right gives 6,000.

A \(40{,}000\)B \(400\)C \(4\)D \(4{,}000\)

The highlighted 4 is in the thousands column, so it is worth 4,000.

A \(65,210\), \(65,120\), \(65,221\)B \(65,120\), \(65,210\), \(65,221\)C \(65,221\), \(65,210\), \(65,120\)D \(65,120\), \(65,221\), \(65,210\)

Compare hundreds, then tens: 65,120 < 65,210 < 65,221. The second list swaps the first two; the third list is greatest to least.
