1 Exploring Area and Perimeter with Excel and PowerPoint Joanne Rosenberg Sponsor Company: Intel Corporation Morgan Hill Unified School District Grade 3 Summer 2005 Goal: Students will understand the concepts of area and perimeter and present these concepts in Excel and PowerPoint. Objectives: By the end of this unit students will demonstrate the ability to: Differentiate between the concepts of area and perimeter. Name common uses of area and perimeter in a variety of careers. Accurately measure the perimeter of common objects in the classroom. Compute the area of common objects in the classroom using cubes and tiles or graph paper. Gather data on area and perimeter and represent data in a graph. Enter data into an Excel spreadsheet. Use Excel to produce a simple chart or graph and compare data. Create a sample math story problem using area and perimeter and present it in Microsoft PowerPoint. Scan illustrations of their sample area and perimeter problem into their PowerPoint Presentation. Standards: Grade 3 CA Math Content Standards Measurement and Geometry Standard 1.1 Choose the appropriate tools and units (metric and U.S.) and estimate and measure the length of given objects. Standard 1.2 Estimate and determine the area and volume of solid figures. Standard 1.3 Find the perimeter of a polygon with integer sides. Mathematical Reasoning standard 2.4 Express the solution clearly and logically by using the appropriate mathematical notation and terms and language: support solutions with evidence in both verbal and symbolic work.

2 Resources Needed PC, Microsoft Office, printer, scanner, a digital camera, community members to talk about careers, measurement tools, tiles, and unifix cubes, LCD Projector or connection to TV. Prerequisites: At back to school night, ask parents to talk to the class about how they use area and perimeter in their jobs or at home. Instruction: This will be an ongoing unit that will last throughout the whole school year. It will start in September with activities that explore and differentiate between the concepts of area and perimeter, and it will end with a PowerPoint presentation to parents at back to school night in May. Individual lessons will be presented once per week throughout the year with worktime scheduled as needed. When these concepts were presented as a two week unit in the past, I have found that students did not retain the information. This project will provide needed reinforcement throughout the year. September week 1: Give the students a tour of the school. Point out that now we are walking around the perimeter of the school. Go to the playground. Give student commands. Walk around the perimeter of the playground. Now walk into the area of the playground. Repeat on the basketball court, grass area and other areas throughout the week. Ask students to predict which perimeter is bigger. Check by counting steps. Week 2: Have students predict how many cubes it takes to go around the perimeter of their text book and various objects in the class. How many paper clips does it take to go around the perimeter of their desk? Record predictions and data on the following table. Students check predictions and record comparisons.

4 Write about your data. Be sure to make comparions: Week 3: Students graph their data Use the data from your table to make a horizontal bar graph. Item

5 Unit of Measurement Week 4: Introduce Area by using geoboards. Have students make the smallest square possible while you demonstrate on the overhead. Explain that the elastic is the perimeter, while the square inside is the area. Have students experiment with making different squares and rectangles. Draw their shapes on graph paper and label the area and perimeter. Have them label area in square units. Week 5: Have students guess the area of various objects in the classroom. Then have them check their guesses using cubes, tiles, or graph paper. Record guesses and measurement on the following worksheet.

9 Week 6: Enter data in Excel Student Instructions: How to Use Excel You are going to create an experimental spreadsheet before you begin your own. You are a fence builder. You have been asked to build several fences at the school. You want to chart the perimeters of each fence. 1. Open Excel Spreadsheet. 2. Click on cell A2. Down the rows, list the following places:

10 Click on cell B2. The next column will show the measurements in feet of each perimeter. Type in the following measurements: 100, 110, 1,100, 240, 60, 80.

11 Click and drag to highlight both columns: click on Chart Wizard (the Vertical bar graph icon on top) to select a bar graph.

12 Step 1: This Chart Wizard box will pop up. Select the first highlighted sub type. Step 2: Click Next.

13 Click on the Titles tab. Enter the Chart Title Perimeter of School Fences by your name, In the x-axis box type, Types of Fences, and the y-axis, perimeter in feet.

14 Click on the Legend tab. 2. Click on the Show Legend box to delete the check mark.

15 Click Next, and select Chart Location as a New Sheet.

16 Click Finish to view your chart. 1. Print your chart. 2. Open a new page in Excel and make a chart from the graph you made by hand. 3. Print your new graph and save it in your documents folder. Reference: with Excel and PowerPoint

17 Week 8: A Sample Area and Perimeter Problem Have students work in groups to make a sketch of the problem and a mathematical solution. Provide little Snickers bars to measure. Career #1: Bobby Baker Bobby has been asked to bake a cake for his cousin Vinney s going away party. There are expected to be 50 people at the party and Vinney s Mom wants each guest to have a 2 inch square piece of cake. How big does the cake have to be? Make a sketch on a separate piece of paper. Show a math calculation: In addition, Vinney loves little Snickers bars, so Vinney s Mom has asked Bobby to put Snickers around the perimeter of the cake. How many Snickers bars does Vinney need? Sketch the Snickers on your cake drawing. Show your math calculation. **If students do a fantastic job, bake a cake with your student s cake dimensions as an end of project celebration.

18 Choose a Career and Design a Project 1. Get together in groups of four and choose a career where area and perimeter are used. Our Career Choice: Project Title: 2. Be creative, write a story about your career person s project and provide a calculation for the project. the needs to: Circle one: Build Design Decorate Brainstorm a project your career person will complete in which area and perimeter are used. 3. What does your career person need to do? Add lots of details.

19 4. What are the measurements or dimensions of the items in your project? 5. Sketch it on a separate sheet of paper. 6. Ask a question or tell about the problem your career person needs to solve. 7. See me to check for accuracy. 8. Make your PowerPoint presentation.
