The benefit of students understanding the properties of perimeter and area gives the learners tools to reason with in daily life. Students will have learned skills that can be transferred both to their personal lives and their jobs. This lesson will help students understand the concepts of perimeter and area and how to use this knowledge in home and office improvements and/or repairs.
At the end of this lesson, students will be able to:
know concepts of perimeter of a rectangle.
know concepts of area of a rectangle.
understand concepts of perimeter of a rectangle and be able to solve for perimeter.
understand concepts of area of a rectangle and be able to solve for area.
Student Target
“I can ...
determine the perimeter of a rectangle."
determine the area of a rectangle.”
CCR Focus Standards
Geometry - Level B
Recognize area as an attribute of plane figures and understand concepts of area measurement.
a. A square with side length 1 unit, called “a unit square,” is said to have “one square unit” of area, and can be used to measure area.
b. A plane figure which can be covered without gaps or overlaps by n unit squares is said to have an area of n square units.
Number and Ratios - Level C
Geometry - Level C
Supporting Standards
Solve real world and mathematical problems involving perimeters of polygons, including finding the perimeter given the side lengths, finding an unknown side length, and exhibiting rectangles with the same perimeter and different areas or with the same area and different perimeters.
Apply the area and perimeter formulas for rectangles in real world and mathematical problems. For example, find the width of a rectangular room given the area of the flooring and the length, by viewing the area formula as a multiplication equation with an unknown factor.
Use place value understanding to round multi-digit whole numbers to any place.
