Unit 7, Lesson 9
Representing Small Numbers on the Number Line
Accelerated 7
Preparation
Lesson Narrative
In this lesson, students use the number line and negative exponents to explore very small numbers. They attend to precision when deciding how to label the powers of 10 on the number line and how to plot numbers correctly (MP6). Students write very small numbers as a multiple of a power of 10 and as a decimal value. While students explore different ways to express these numbers as a multiple of a power of 10, the use of a number line encourages the form
- Coordinate (orally and in writing) decimals and multiples of powers of 10 representing the same small number.
- Use number lines to represent (orally and in writing) small numbers as multiples of powers of 10 with negative exponents.
Let’s visualize small numbers on the number line using powers of 10.
