## Reflection: Connection to Prior Knowledge The Circle (Day 1 of 2) - Section 2: Bell Work

Even though some popular Precalculus books do not introduce circles with the other conic sections, I like to treat conics as a coherent unit.  I think that beginning with circles is a great way to review concepts like completing the square. Also, by the time my students reach my Precalculus class, most have worked with circles. So, starting conics with circles is a good way to help students gain confidence at the start of this unit.
