Find the Missing Part in Expanded Form

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 form worksheets work well as daily practice, homework, or a focused review activity.

Find the missing part in 10 expanded forms, such as the thousands in 6,846 or the tens in 2,784. In expanded form, each part is the value of one digit: 3,512 = 3,000 + 500 + 10 + 2. The directions on the page read: Look at each number and its expanded form. Then, write the missing part in the box. 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 form. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.

Expanded form writes a number as the sum of the value of each digit. 6,324 = 6,000 + 300 + 20 + 4, because the 6 is worth 6,000, the 3 is worth 300, the 2 is worth 20 and the 4 is worth 4.

A digit that is 0 adds nothing, so it is skipped. On Expanded Form of Numbers With Zeros, 1,704 = 1,000 + 700 + 4 and 9,700 = 9,000 + 700.

Yes. Adding the parts by place value gives the same number in any order. On Expanded Form to Standard Form, Mixed Order, 2 + 90 + 300 + 9,000 = 9,392.

Yes. All 5 expanded form sheets have an answer key.
