Lesson objective: Represent three-digit numbers using word form.

This lesson helps to build procedural skills with writing three-digit numbers in word form. Base ten blocks and expanded notation are used here because they support understanding of the value of each digit in a number. This work develops students' understanding that there are a variety of equivalent ways to represent a number.

Students engage in Mathematical Practice 7 (Look for and make use of structure) as they rely on place value patterns to write numbers in word form.

Key vocabulary:

• expanded form
• hundreds
• ones
• tens
• value
• word form

Special materials needed:

• base ten blocks
• place value mat (optional)
