Standard and Expanded Form

Worksheet Description

This worksheet is designed to practice the concepts of expanded form and standard form with three-digit numbers. At the top, it provides examples of how to write numbers in expanded form, such as “359 = 300 + 50 + 9” and “534 = 500 + 30 + 4”. The first section below the examples asks students to write each given three-digit number in expanded form, reinforcing their understanding of place values. The second section provides examples of numbers written in expanded form and requires students to rewrite them in standard form, testing their ability to reverse the process.

The purpose of this worksheet is to solidify a student’s grasp of place value by converting numbers into expanded form, which breaks them down into their constituent hundreds, tens, and ones. It also teaches them to synthesize this understanding by doing the opposite, composing standard form numbers from their expanded components. This dual approach not only reinforces the arithmetic value of each digit according to its position but also builds flexibility in number manipulation. These skills are essential for students as they progress to more complex mathematical concepts that rely on a strong foundation in place value.
