Lesson Plans

Name Description
Zoning with Area and Perimeter Part 3:

This is Part 3 of the Zoning with Area and Perimeter lesson. Students will be asked to increase the area of each zone they created in Parts 1 and 2. They will then determine the perimeter of each zone based on its new area measurements.

Zoning with Area and Perimeter Part 2:

This is Part 2 of the Zoning with Area and Perimeter unit. Students will be asked to place and zone three schools to serve the students of the community. They will be provided the perimeters of each school and will need to maximize its area in this integrated lesson plan.

Zoning with Area and Perimeter Part 1:

Students will hold a town hall meeting to zone a new community. They will assign a different area measurement to each zone and then determine the zone’s perimeter. Students will explore how rectangles with the same area can have different perimeters in this integrated lesson plan.    

Volunteer Trash Cleanup:

In this Model Eliciting Activity (MEA), students will help a volunteer coordinator choose cleanup projects that will have the greatest positive impact on the environment. Students will learn about how litter and pollution can affect wildlife as well as how cleanup efforts can help. They will discuss the importance of volunteering in the community and utilize math skills such as calculating area in deciding how to rank the different cleanup projects.

Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. Click here to learn more about MEAs and how they can transform your classroom.

New Puppy's Pen:

The purpose of this lesson is to help students find the missing side's length for rectangular area problems, when the total area and one side's length is given. The use of square tiles, then graph paper and equations are used throughout the lesson to help students progress from conceptual to procedural knowledge.

Its All Around But Covered Up:

Students explore missing dimension challenges in real world area situations.

Draw a blueprint of your dream house floor plan.:

This lesson will help your students learn about area and perimeter while imagining and drawing a blueprint of their dream house floor plan. They will have so much fun drawing and creating their blueprint they will forget that they are actually learning how to find area and perimeter. 

Numbers Grow Here:

The students will use prior knowledge of the area formula to design a garden with a  area. Students will compare gardens and note that rectangles with the same area could have different dimensions.

Playground Perimeter:

In this Model Eliciting Activity (MEA), students are asked to help rank possible locations for a new park. They will need to perform certain calculations as part of the process, such as finding the unknown factor in a perimeter and area formula and multiply 2-digit by 1- and 2-digit numbers to calculate total costs.

Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. MEAs resemble engineering problems and encourage students to create solutions in the form of mathematical and scientific models. Students work in teams to apply their knowledge of science and mathematics to solve an open-ended problem, while considering constraints and tradeoffs. Students integrate their ELA skills into MEAs as they are asked to clearly document their thought process. MEAs follow a problem-based, student centered approach to learning, where students are encouraged to grapple with the problem while the teacher acts as a facilitator.

Park Planning:

Students are asked to plan a playground for a new park within a given budget and area limit. They will analyze the best use of playground equipment using a data table of area requirements and cost. Students will convert units within a single measurement system, calculate the area of a rectangle, and perform addition/subtraction calculations involving money using decimal notation.

Pioneer Places:

In this MEA, students decide which type of pioneer dwelling was the best to build if you were traveling west.

Perimeter - It's a Linear Measurement:

In this lesson, students will review finding perimeter of polygons and apply their knowledge of finding perimeter and area to compute unknown side lengths. Students draw rectangles with a specific perimeter and draw rectangles with a specific area but different perimeters.

Same Perimeter, Different Area:

In this lesson, students are presented with a problem that requires them to create rectangles with the same perimeter but different areas.  Students also search for relationships among the perimeters and areas of different rectangles and find which characteristics produce a rectangle with the greatest area.

No Spare Space:

In this lesson, the students are employees of a fencing company. They are working with a customer to try and get the best deal and design of a fence that will fit the customer's area needs. Students will have to use reasoning skills in order to fill in missing information. Students will also discuss whether or not their designs have met the needs of the customer.

Bre and Brent the Builders:

The students will be able to use prior knowledge of the concept of area to relate area to multiplication and discover the formula: base x height. Students will practice by composing two-dimensional squares and rectangles and apply the area formula to build a birdhouse.

Wallpaper Woes Money Math: Lessons for Life:

Students hear a story about a middle-school student who wants to redecorate his bedroom. They measure the classroom wall dimensions, draw a scale model, and incorporate measurements for windows and doors to determine the area that could be covered by wallpaper. Students then hear more about the student's redecorating adventure and learn about expenses, budget constraints, and tradeoffs.

Area and Perimeter of Rectangles Investigations:

Students will determine the validity of the statement, "All rectangles with the same area will have the same perimeter" through two investigations.

House Building Architects:

In this lesson, students are tasked with drawing a house based on given directions. The directions include the area and perimeter of particular features of the house. This resource is recommended as a review of perimeter and area.

Light It Up:

In this MEA, students will work in collaborative groups to solve real-world, multi-step problems with whole numbers and decimals by using different mathematical operations such as addition, subtraction, multiplication and/or division. The students will be asked to assist a business/property owner in purchasing holiday lights for his property. They will need to read several ads and decide which product would be the best for the property. They will be provided with an office plan to calculate the perimeter of the building to then calculate how many holiday lights will need to be purchased and its total cost for each. They also need to take into consideration the owner's primary concerns. In the twist, the owner finds different holiday lights made from another material.

Problem-Solving Task

Name Description
Karl's Garden:

The purpose of the task is for students to solve a multi-step multiplication problem in a context that involves area. In addition, the numbers were chosen to determine if students have a common misconception related to multiplication. Since addition is both commutative and associative, we can reorder or regroup addends any way we like. Students often believe the same is true for multiplication.
