Lesson objective: Represent three-digit numbers that include a zero as one of the digits.

This lesson helps to build fluency with place value concepts. Base ten blocks are used here because they support visualizing the value of each digit. This work develops students' understanding that the digits in a three-digit number represent hundreds, tens, and ones, from left to right.

Students engage in Mathematical Practice 4 (Modeling with mathematics) as they model three-digit numbers using place value blocks. They analyze these models to formulate their own generalizations and draw conclusions, improving the models if needed.

Key vocabulary:

• hundreds
• ones
• place value blocks
• representations
• tens
• zero

Special materials needed:

• place value blocks - hundreds, tens, ones
