What this practice page covers
This expanded form worksheet includes an original practice page and a separate answer page. Expanded form makes the value of each digit explicit. This page uses three-digit whole numbers and asks for all three terms, including a zero term.
Work through an example
The number 507 is 500 + 0 + 7. The zero tens term shows that the number has no tens, rather than moving the seven into the tens place. Read the instruction before starting, and use a spare sheet for intermediate working if the answer space is not enough.
Review the method as well as the answer
After expanding a number, add the terms to check that they return the original value. A place-value chart can provide support before learners write the expression independently. Try the exercise page before opening the key. When an answer differs, compare the steps and correct the specific misunderstanding rather than copying every result. The page is focused practice, not a complete assessment of the wider topic.
