Preparation
Lesson Narrative
The purpose of this lesson is to support students when they work with area and perimeter of rectangles. It prepares them to recognize linear and non-linear relationships presented in multiple ways in later lessons. When students complete the tables and write expressions for area and perimeter, they are expressing regularity in repeated reasoning (MP8).
- Comprehend (in written and spoken language) the term “area” to refer to the amount of square units that fill the inside of a 2-dimensional shape and the term “perimeter” to refer to the linear measurement around a shape.
