Common Core Math - Grade 4
Lesson Plan
Apply the area and perimeter formulas for rectangles in real world and mathematical problems
Goals / Objectives
Use the area formula A = l x w to find the area of a rectangle when both dimensions are given
Use the perimeter formula P = 2l + 2w (or equivalently P = 2(l + w)) to find the perimeter of a rectangle when both dimensions are given
Find an unknown dimension of a rectangle given its area and one side length, by viewing the area formula as a multiplication equation with an unknown factor
Find an unknown dimension of a rectangle given its perimeter and one side length
Determine whether a real-world problem requires area or perimeter based on context clues, and select and apply the correct formula
