Flowchart to quickly classify a conic as a parabola, circle, ellipse or hyperbola.
3 Pages: Handout (Lesson) / Worksheet / Key
Equation editor software within MS Word is used for a clear, professional look.
Word is needed to print. MathType is needed to edit equations.
Page 1 is a handout that clearly, visually, and concisely articulates a flowchart method to classify a conic (of the form Ax^2 + Bxy + Cy^2 + Dx + Ey + F = 0) as a parabola, circle, ellipse, or hyperbola. No computation or written student work is needed. This method is much easier than the method of using the discriminant that is described in many textbooks.
Page 2 is an 20-question worksheet with room for student responses. No room is needed for student work.
Page 3 is the KEY for Page 2 (questions with answers).

This is basically a worksheet. The flow chart is nice though.
