## Reflection: Unit Planning Relationship Between Circumference and Diameter - What is pi? - Section 2: Explore

I do not spend an entire day on this lesson.  As luck had it this year, the lesson fell on a make up snow day which was an early release and fell on a Saturday - so this lesson was perfect for a 30 minute class.  In the past, I have done this lesson during our school's focus time - which is a 30 minute block in the morning, and I have had all teachers on my team do the lesson (so they could take part in the food, and so that all kids would get the lesson).  Additionally, I have done this lesson as the first day of the unit, but split the time by giving the class a pretest on the unit.
