Reflection: Connection to Prior Knowledge The Defining Pi Project, Day 2 - Section 1: Opener: Example Problem from Gallery Walk

This historical discussion of Fibonacci's approximation for pi takes us through two Mathematical Practices: attention to precision (MP6) and use of the calculator as a tool (MP5). It also serves as a brief review of scientific notation. There is a lot of good mathematical thinking to be had, even as students are being exposed the history of the subject (or of a number).

Planning note: When I am teaching this lesson, I pay attention to student thinking and the misconceptions that arise when students begin the Gallery Walk. Fibonnaci is often a good choice for my students at my school. However, I my choose to use what I observe to choose the most appropriate problem to share as a full-class example, based on something interesting that occurs on Day 1.

Connection to Prior Knowledge: Mathematicians and Mathematical Practices

The Defining Pi Project, Day 2

Unit 6: Trigonometry: Circles
Lesson 6 of 17

Big Idea: This lesson picks up where Day 1 left off, providing students with clarity about Part 1 of the project and the levels of precision to which we will have to attend.
