Lesson 4

Write Three-digit Numbers

Lesson Purpose

The purpose of this lesson is for students to use their understanding of place value to identify and write three-digit numbers.

Lesson Narrative

In previous lessons, students learned that the three digits in a three-digit number represent amounts of hundreds, tens, and ones.

In this lesson, students build on this understanding to write three-digit numbers when the number or value of the hundreds, tens, and ones are shown in different orders. Throughout the lesson, students practice identifying and writing three-digit numbers using their understanding of place value.
