Naming 3-Digit Numbers

Worksheet Description

This worksheet is a learning tool for students to practice writing numbers in expanded form. It presents a series of three-digit numbers, each partially written in expanded form, with one part of the number left for the student to fill in. For instance, for the number 867, the expanded form is started as “800 + 60 + __,” and the student must complete it by writing “7” in the blank. This format allows the student to focus on understanding each digit’s place value within the number.

The worksheet is teaching students how to deconstruct three-digit numbers into their constituent parts according to place value. It emphasizes the hundreds, tens, and ones places and how each contributes to the overall value of the number. By completing the expanded forms, students practice recognizing and writing the value of each digit in its correct place value position. This exercise strengthens their understanding of the base-ten system, which is fundamental for all further mathematical concepts involving numbers.
