Using this page
Write numbers in expanded form, such as 4,325 = 4,000 + 300 + 20 + 5, or turn expanded form back into a number. Choose three to six digits. Some numbers include a zero, which is left out of the expanded form. The Common Core uses expanded form in Grade 2 for numbers to 1000 and in Grade 4 for larger numbers. Suits around Year 2 to Year 4 in Australia and Grades 2 and 4 in the US (Common Core 2.NBT.A.3 and 4.NBT.A.2), but use whatever level fits the child.
Tips
- Show the working, even when the answer seems obvious; it makes mistakes easy to spot.
- Check each answer: put it back into an equation, or estimate before working out.
- Start with the easier setting and move up once most answers are right.
- Mix one older sheet into each week so earlier skills stay fresh.
Worked example
4,075. Thousands: 4 is worth 4,000. Hundreds: 0 is worth nothing, so it is left out. Tens: 7 is worth 70. Ones: 5. So 4,075 = 4,000 + 70 + 5. Going back, 4,000 + 70 + 5 = 4,075, with a zero to hold the hundreds place.
Common mistakes
Writing the digits instead of their values: 4 + 0 + 7 + 5.
Forgetting the zero placeholder when going back, writing 475 for 4,000 + 70 + 5.

Common questions
Why are some numbers printed with commas?
Numbers of 1,000 and above are printed with a comma between the thousands and hundreds, which is a common way to write them in Australia, the US and the UK.
