Worksheet Preview
Expanded form makes place value visible
Expanded form is place value written out: 234 = 200 + 30 + 4. It forces students to say what each digit is really worth — the 3 is thirty, not three. Numbers with a zero (like 409) are the teaching moment: the zero holds the tens place, and expanded form shows it as ”+ 0 +”.
How to use it
Start from the base-ten blocks on the first problems so the value of each digit is concrete, then move to writing expanded form straight from the numeral. Emphasize the zero place in numbers like 409. This builds directly on hundreds, tens, and ones.
👩🏫 Teacher note
Expanded form makes place value explicit: the 3 in 234 is worth 30, not 3. Start from the base-ten blocks so the value of each digit is visible.
🏠 Parent note
Break the number apart by place: 234 is 200 + 30 + 4.
Common Mistakes to Watch For
- Writing the digit instead of its place value (3 instead of 30)
- Dropping the zero place (writing 200 + 5 without showing the missing tens)
Answer Key
