Finding Pi

Activity Overview

Students discover that pi is the ratio of a circle's circumference to its diameter using manipulatives and the Nspire's data capture feature.
This activity can be accomplished individually or in groups of 2 or 3.

Before the Activity

Load or have the students load the tns file: finding pi.tns

Copy the attached "circles" document

The circle document does not include the diameter. Students should move the ruler around the circle to find the diameter or the teacher may draw the diameter for each circle before copying the sheet.
