Reflection: Connection to Prior Knowledge Circumference and Area - Section 1: Launch

Finding the circumference was a little challenging. Students substituted the diameter into the equation that they remembered and suddenly the area of the circle became the answer for the circumference. We worked on identifying the elements of the formula and exactly what the radius and diameter are and what they represent. I was excited that they had some knowledge of circles.
