Rebuild Numbers From Expanded Notation

Before handing out the worksheet, briefly introduce the concept with a short oral warm-up or a visual model on the board. Let students work through it independently, using a partner or small group only if they want to talk through their thinking, encouraging them to talk through their thinking: "What strategy are you using? How do you know that is right?" After completing the worksheet, review any missed problems together and discuss the reasoning rather than just the answer. For extra support, let students use manipulatives or draw pictures alongside the written problems. These expanded notation to standard form worksheets work well as daily practice, homework, or a focused review activity.

Rebuild 10 numbers from expanded notation like (7 x 1,000) + (3 x 1), writing a 0 for each missing place. Expanded notation writes each digit times its place value. A place that is not shown has the digit 0: (4 x 1,000) + (6 x 1) = 4,006. The directions on the page read: Find the value of each part and add the parts. Then, write the number in the box, with a 0 for any place that is not shown. An answer key is included.

Yes, both. We made it for 3rd Grade place value and rounding, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with expanded notation to standard form. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.

Multiply each digit by its place value, then add the parts. (6 x 1,000) + (8 x 100) + (5 x 10) is 6,000 + 800 + 50 = 6,850.

A place that is not shown has the digit 0. (8 x 1,000) + (1 x 10) + (7 x 1) has no hundreds part, so the number is 8,017.

Yes. Both sheets have an answer key.
