The lesson we developed and then taught was an introduction to conditional, converse, and bi-conditional statements. We pre-taught the first half of the lesson to a group of summer math camp students (8th - 12th grade) and then we taught the full lesson to a class of students at a junior high in Park City.

Geometry or Integrated 1
CLASS TIME
