Instructional Ideas

• Have class members try to find at least two series that will work for each problem
• Use the components in the lesson in a flipped classroom setting

Classroom Considerations

• There are many different combinations that will work for each problem
• The lesson is seventh in an 11-part unit on congruence and similarity

Pros

• Answer key provides solutions that follow the method provided
• The pre-image and image are different colors/shades

Cons

• Relies strictly on direct instruction to impart information
