LESSON PLAN: Tackling Trigonometric Graphs & Transformations

Tomorrow I will be "introducing" graphs of trigonometric functions to my IB Math Standard Level 1 class, so I've got Trig on the brain.  Yes, yes, they already learned it in Algebra 2/Trig Honors, but I find that it's best to build from the ground up when it comes to Trigonometry.  Sometimes students catch something … Continue reading LESSON PLAN: Tackling Trigonometric Graphs & Transformations

Graphing Functions: A Table Approach

Algebra 1:  Graphing's a cinch!  (For us... maybe not so much for our students) We teach linear and quadratic parent functions... and often fail at inverse variation We begin to help them understand the usefulness of finding the vertex and substituting values for x. We show the connection between evaluating and the graphing calculator table … Continue reading Graphing Functions: A Table Approach
