Using a Graphing Calculator in an Algebra 2
Classroom
Why we need to teach these skills
• Build confidence with technology and math• Calculators are a tool for learning
mathematics• Teaching math through discovery• Skills needed in other courses – Common
Core
The Four Calculator Skills Required on the AP Calculus Exam
1. Graph a function in an appropriate window.2. Solve equations numerically, use Solver, find
intersections, and graph functions.3. Find the numerical value of a derivative at a
point.4. Evaluate a definite integral.
Philosophy
• Teach the math concepts using the calculator• Always connect calculator skills to the math*• Allow time for them to play and practice
(project)• Make it fun• Don’t be afraid that you don’t know how to do
something. Ask them. Discover together.• Have students communicate what they are
learning to their fellow students.
Tips for introductory
• Put a calculator in their hands as early as Algebra 1
• Simple math – learn the keyboard, On button• Instruct then practice, or use guided
activities, or group work• Practice, practice
Sample Algebra 2 Topics
• Linear functions• Window (no zoom)• Finding intersections
• Quadratic Functions• Finding zeroes, maximum/minimum• Factoring• Transformations• Applications
• Matrices• Multiplication• Solving Systems of Equations (RREF)
Sample assignments and projects
• Practice Sheet – Calculations • Window Calculator Exercise• TI – 84+ Caching Games Mathbits.com• Make These Designs Project• Transformation Project
Resources online
• Websites: www.mathbits.com, • YouTube videos• Apps – IPad graphing calculators • Quick Reference Sheets• TI – Classroom Activities • TI – Classroom Projects• Calculator functions also used in Calculus
Tools to help facilitate
• TI Smartview Emulator Software– very helpful even without a smart board
• Class sets of calculators• TI Posters
