4.MD.3 - 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.
Area Formula for Rectangles - Playlist and Teaching Notes
In this playlist, students explore standard 3.MD.C.7B. They will apply the area formula for rectangles with whole-number side lengths. Students will apply mathematical reasoning to find the length of a side when given the whole number area of a rectangle. Students also have the option to view instructional videos and complete practice quizzes or activities. @WisewireEd
Colorful visual representation of area formulas for rectangles, triangles, parallelogram, triangles, trapezoids, and circles. Great addition to the classroom for elementary education and extremely helpful for remembering area!

Area and Perimeter Task Cards
Looking for a way to give your students additional practice with area and perimeter skills? This set of 20 cards increases in difficulty throughout the set. The first cards involve counting squares to find area and perimeter. As the set progresses, students use the area and perimeter formulas to solve “open” rectangle problems. Finally, the last 8 cards have “irregular” shapes that require students to either decompose the shape into smaller rectangles. Use as a math station…as a class…
