Project Sketch #2 Cell Phone Usage

11th grade Algebra 2 class

After a review of writing and graphing linear equations, the Cell Phone Usage PBL will be introduced. My project idea is to have students analyze their own voice and text usage then based on their use choose the best provider and plan for them. Students will need to compare and contrast provider coverage, and three levels of plans: 450 minutes, 900 minutes, and unlimited. Throughout the compare and contrast of usage plans, students will write one linear equation per plan and use graphing calculators to graph them. Furthermore, students will use graphing calculators to find the intersections point or points of the linear equations. After students have determined the best plan for their usage needs, they will create a persuasive presentation to convince the audience that they could not get a better deal for their needs. The presentation products may vary from group to group, but a rubric will clearly define key learning outcomes and guide their work. I expect this project to last one week, two in class work days, two days and nights out of class, and the third and fourth day will be presentation days.

4. Q: Using one core concept, what real life contexts and other subjects can be incorporated?
A: Systems of Linear Equations, making consumer choices, choosing a cell phone plan and company.

5. Q: Incorporate Bloom’s Taxonomy to push past rote learning.
A: Inventory and Examine students’ own voice and text usage.
Compare and Contrast voice and text plans.
Formulate a linear equation for each plan.
Support and Argue which plan and/or provider is best for students’ own usage.

6. Q: Authentic interactions and 21st century skills
A: Students could visit a provider store to investigate and discuss which plan would best fit their usage. Use graphing calculator to graph equations and to locate intersection points. Collaboration with classmates in small groups to analyze voice and text plans.

7. Q: Students’ interests?
A: Every student has a cell phone or wants one students can use this info to show their parents better deals. May need to use cell phone during class to look up personal usage information. Students learn to compare and contrast similar service providers which has many more applications than just cell phone providers.

8. Q: Learning dispositions
A: Curiosity, cooperation, persistence, resourcefulness, motivation, self-directedness

Evidence of Understanding
Students will create and present a persuasive argument. Students will need to analyze their own usage habits and investigate cell phone providers and the plans they offer to best fit their needs and be economical. Students will write a system of three linear equations and graph them. Students will use a graphing calculator to graph equations and find the interception of the lines.

Project Theme or Challenge
Find the best cell phone provider and plan for your own usage habits.

Introduction to Project
Students will be asked to bring cell phones to class. Then asked to look up their monthly text and voice usage.
