Number words worksheets: writing 679 as six hundred seventy-nine
Six hundred seventy-nine, or six hundred and seventy-nine? Both are right, and the sheet lets you pick. Either way the teens are where kids trip.
A check for the school fundraiser needed the amount in words. My third grader watched me write “one hundred forty-five” and asked why there was no “and”. Her grandmother, who went to school in India, would have put one in. Both are correct, which is exactly the kind of thing a worksheet should let you choose instead of deciding for you.
What the sheet looks like
The number words generator prints a worked example at the top of every sheet, then eight to sixteen problems. You pick the direction: number to words (679 becomes six hundred seventy-nine), words to number, or a mix. Ranges go 0–20, 0–100, 3-digit and 4-digit, which line up with kindergarten through third grade. The word style switch flips between US wording and the UK and India style with “and” after the hundreds.
Why it works
- Writing fifty-six as a word makes the child say the tens and the ones separately. That is place value practice without a place value chart.
- The teens are the trap. Thirteen, fourteen and fifteen do not follow the pattern, and the 0–20 range exists to hit them over and over.
- Words to number is the harder direction. “Four thousand six” has no hundreds and no tens, and a child who writes 4,600 has just told you what to work on next.
Who it suits
The 0–20 range is a kindergarten sheet and will bore anyone older. By fourth grade the 4-digit range is still worth doing for the numbers with zeros in them, but not for much else. If the child is unsure which digit is the hundreds, start with the place value worksheet and come back to this one a week later.
One sheet a week through the fall is plenty.
