Instructional Ideas

• Though the lesson divides the work for the first exercise, it may be beneficial for each pupil to do all the calculations
• If the class is well versed in the scaling properties for area, you can skip the opening exercise or assign it as homework before the lesson

Classroom Considerations

• Some may have difficulty simplifying the ratios
• The ninth installment of a 14-part series

Pros

• The lesson plan contains scaffolding suggestions throughout
• If it is necessary to split the lesson over two days, suggestions include what to use on the first day and how to continue on the second day

Cons

• None
