Standard vs Expanded Forms

Expanded and standard forms are two essential ways to represent numbers in mathematics. Standard form, or the numerical form, is the most straightforward representation of a number, where the digits are arranged in their usual place value order. The expanded form breaks down a number into its constituent parts, emphasizing the value of each digit’s place within the number. Expanded form is a valuable tool for teaching students about place value and understanding the composition of numbers.

In this worksheet, students will show their understanding of 3-digit place value numbers with how to read and write using Base Ten blocks, standard form, and expanded form.
