Updated: Now includes print and digital options for the lesson. Perfect for distance learning or the paperless classroom. Interactive student notes, exit ticket, and homework for Google Slides™.
In this lesson students will relate significant figures with the digits recorded for measurements. In the preceding lesson, students learned the correct way to record a measurement by recording the numbers that are certain and estimating one more digit. Here, we name those recorded digits significant figures. I have found by teaching sig figs in this way, students will more readily accept sig figs, understand the importance of sig figs, and be ready to use them for the rest of the year.
Lesson Objectives:
* Describe the importance of significant figures

Precision, and measurement skills showing precision
