This page describes the various two dimensional conic sections that can be obtained.[http://en.wikipedia.org/wiki/Conic_section]
==Concept #1 Circle==
==Concept #1 Conic sections==
===Learning objectives===
===Learning objectives===
# Children develop an appreciation of a circle as a conic section.
# Conic Sections are figures that can be formed by slicing a three dimensional right circular cone with a plane.
# There are different ways to do this, and each way yields a different figure.
# These figures can be represented on the graph as well as algebraically.
# The four conic sections are circles, ellipses, parabolas, and hyperbolas.
===Notes for teachers===
===Notes for teachers===
# The general equation for all conics is <math>Ax^2+Bxy+Cy^2+Dx+Ey+F=0</math>
# If <math>B^2-4AC<0</math> then the curve is an ellipse, circle, point or no curve.<br>
# If <math>B^2-4AC=0</math> then the curve is a parabola,2parallel lines, 1 line or no curve.<br>
# If <math>B^2-4AC>0</math> then the curve is a hyperbola or 2 intersecting lines.<br>
