Help students practice their knowledge of 3-digit numbers with this place value worksheet that covers base ten blocks, standard form, and expanded form.

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.
