Applications of Area Abound


The teacher will first provide direction instruction on area formulas and provide students an opportunity to practice using those formulas. Students will then apply their knowledge of area to real-life situations. They will write a short story to go along with the area problem, then record themselves "acting" it out, and finally add clip art images to illustrate their story. They will then turn all of this into a podcast using Photo Story 3, which can be uploaded to the Internet.

 Associated Standards and Objectives 
Content Standard(s):
TC2 (9-12) Computer Applications
12. Use digital tools to publish curriculum-related content.
Examples: Web page authoring software, coding software, wikis, blogs, podcasts
MA2015 (6)
21. Find the area of right triangles, other triangles, special quadrilaterals, and polygons by composing into rectangles or decomposing into triangles and other shapes; apply these techniques in the context of solving real-world and mathematical problems. [6-G1]
MA2015 (7)
14. Know the formulas for the area and circumference of a circle, and use them to solve problems; give an informal derivation of the relationship between the circumference and area of a circle. [7-G4]
MA2015 (7)
16. Solve real-world and mathematical problems involving area, volume, and surface area of two- and three-dimensional objects composed of triangles, quadrilaterals, polygons, cubes, and right prisms. [7-G6]

Local/National Standards:


Primary Learning Objective(s):

The student will demonstrate and apply knowledge of the formulas for calculating area of polygons. The student will create a podcast that both illustrates and narrates a real-life area problem with clarity and correctness.

Additional Learning Objective(s):

The student will develop the ability to verbally communicate mathematical concepts and processes to others.

 Preparation Information 

Total Duration:

Greater than 120 Minutes

Materials and Resources:

Gauging Student Needs PowerPoint Sample real-life problems Creating a Podcast using Photo Story 3 handout

Technology Resources Needed:

Computers; Interactive whiteboard; projector; presentation software; Photo Story 3; Windows Media Player


Some real-life area problems are provided in the handout, but the teacher may need to create more real-life problems for the students to solve. The teacher will also gather the necessary materials and technology equipment. The teacher will install the free download of Photo Story 3. The teacher will create or have a blog or web site to which the podcasts can be uploaded. The student will need experience using presentation software.

1.)Show the Gauging Student Needs presentation and complete the KWL chart, as well as the concept map of ways area can be used in real life. Use the information gained here to judge how much instruction the students will need in step 2.

2.)Teach students how to use the formulas for areas of triangles, rectangles, parallelograms, regular polygons, and circles using direct instruction (or other method).

3.)Provide opportunity for students to practice using the formulas.

4.)Assign students to groups of 2 or 3. Explain the area podcast activity and go over the podcast rubric so that students will know what is expected.

5.)Assign each group a real-life area problem to work. Have them work it, and check their work to be sure it is correct.

6.)After students have the steps correct, allow them to work the problem out on an interactive whiteboard and save this file as an image to be used later when they create the podcast. They may need to save separate steps of the problem as separate image slides. This will become evident to the students as they work on their short story. Save the files so that they can be edited later if necessary.

7.)Students will then write a short story that revolves around their real-life area problem. They should have the same number of characters in the story as people in the group so that everyone can participate in the recording.

8.)Have students swap stories with another group and read them for clarity. Revise as necessary.

9.)Students will then choose pictures from Clip Art or other free image sites to illustrate their short story. They will insert each picture into its own slide in the presentation software so that they coincide with the order of the story.

10.)Follow the steps on the Creating a Podcast Using Photo Story handout to save the presentation slides as images and load them into Photo Story.

11.)Record the narration for the slides in Photo Story using the script that the students wrote.

12.)Save the project and then convert it to a movie file following the directions on the handout.

13.)Upload the podcasts to the teacher's blog or website. Present them to the entire class and perhaps a middle school math class as well.

**Some files will display in a new window. Others will prompt you to download.

Assessment Strategies

Rubric for podcasts (attached) Area Test that includes some real-life problems


Have students who are more advanced write their own real-life area problems to solve, narrate, and illustrate.


Provide time for those students who are not familiar with presentation software to come in before or after school to obtain extra help learning to use presentation software. In addition, make sure that those students are paired with students who are more knowledgeable of the software.

Each area below is a direct link to general teaching strategies/classroom accommodations for students with identified learning and/or behavior problems such as: reading or math performance below grade level; test or classroom assignments/quizzes at a failing level; failure to complete assignments independently; difficulty with short-term memory, abstract concepts, staying on task, or following directions; poor peer interaction or temper tantrums, and other learning or behavior problems.
