What's My Line


Overview:

This activity is for students enrolled in an Algebra 1 mathematics class or above. Students should have some knowledge of descriptive statistics and be able to use the TI-83 graphing calculator and the Calculator Based Ranger (CBR).

Materials Needed:

  1. Worksheet #1

  2. Worksheet #2

Teacher Preparation:

  1. Basic directions for the CBR are enclosed with the units. *****link to TI site and getting started with the CBR*****

  2. It is important that you demonstrate data collection with the CBR for the students. Ask them questions of the different graphs that are created.

  3. Students should have enough room to be able to walk in a clear path. Sometimes you will have to allow student pairs to go in the hallway outside the classroom to complete the data collection.

  4. If you have a computer in your classroom with the TI-Graph Link, students can print their screenshots and paste them onto the lab sheet instead of sketching on the graph.
