Three-Digit Number Names Worksheets
Connect each number name to hundreds, tens, and ones. A zero holds a place even when its name is not spoken.
Read the hundreds first
The number 346 has three hundreds, four tens, and six ones. Its name is three hundred forty-six. Read the hundreds, then name the remaining two-digit number.
346 ↔ three hundred forty-six
300 + 40 + 6
The words describe the same quantity as the digits. Forty-six means four tens and six ones, not forty and sixty.
Keep empty places when writing digits
Five hundred seven is 507. There are five hundreds, no tens, and seven ones. Writing 57 would mean five tens and seven ones, a different number. The zero keeps the seven in the ones place.
Five hundred seventy is 570. The seven represents tens, and there are no ones. Compare 507 and 570 aloud before writing them.
Read a whole hundred
600 is six hundred. There is no need to add zero tens or zero ones to the spoken name. The two zeros are still necessary in the digits.
Notice teen names and tens names
Four hundred sixteen is 416; four hundred sixty is 460. Say sixteen and sixty clearly, then identify their tens and ones. Write forty, not fourty, when naming four tens.
Use a consistent written style
The answer key uses American English number names without “and,” such as two hundred thirty-one. Use a hyphen between the tens and ones in thirty-one. Whole hundreds and round tens do not need that hyphen.
Check by changing back
After writing seven hundred eight as 708, read 708 back aloud. After naming 892, rebuild it as eight hundreds, nine tens, and two ones. Both directions should return to the original number.
About this practice
Each sheet reuses four original questions with four distinct numbers from 100 through 999: two ask for digits and two ask for words. Particular zero digits or teen numbers are not guaranteed in every set.
This activity practices number names and numerals. Expanded form has its own worksheet; quantity pictures and numbers of four or more digits are not assessed here.
