Hundreds, Tens and Ones
Free printable hundreds, tens and ones worksheets for 2nd grade. Three-digit place value in expanded and standard form, with an answer key.
Second grade adds the third place. Every number is between 100 and 999, and each question asks for a digit's place, its value, or the whole number moved between standard form (352) and expanded form (300 + 50 + 2).
Zeros are where three-digit place value goes wrong: 305 is three hundreds and five ones, not thirty-five. About one number in five here has a zero in it, and its expanded form skips the empty place, so 305 is written 300 + 5. When these are secure, the four-digit Place Value page carries on into thousands.

Frequently asked questions
Do the questions ever ask what a zero is worth?
No. The value of the 0 in 305 is zero, which teaches little, so the digit questions use numbers without zeros. Zeros do appear in the expanded and standard form questions, in about one number in five, because a child who writes 305 as 3 + 5 has not yet seen the zero holding the tens place open.
What grade is this?
Second grade, where three-digit place value is taught, with review at the start of third.
How do you write a three-digit number in expanded form?
As its hundreds, tens and ones added together: 352 is 300 + 50 + 2. A place that holds a zero adds nothing, so 305 is 300 + 5.
What kinds of question are on the sheet?
Three, mixed together: writing a number in expanded form (232 = 200 + 30 + 2), putting the parts back together (600 + 10 + 6 = 616), and giving the value of one digit (in 572, the 7 is worth 70). About two questions in three are the first two kinds.
