=Summary of Unit= In this unit, students will learn about problem solving that involves area and perimeter. They will begin the unit by focusing on the units of measurement, and how to properly use them when dealing with perimeter and area. In lesson two, students will be exploring how polygons can break down into regular polygons which can be easier to find the area of. Lesson three builds upon the previous lesson, and challenges students to find the area and perimeters of different irregular polygons, while lesson four will have the students thinking about how to change a polygon, but have the area and perimeter remain the same. The fifth lesson will havve the students using these skills to answer problems that involve the area for any polygon, circle, or combination. The unit will be wrapped up as students argue the importance of units by using the knowledge they have gained throughout the lesson. Through the use of technology and various activities, the students will be involved and engaged during this unit, therefore enhancing their learning experience.

=Establish Goals= Maine Learning Results: Mathematics- C. Geometry Geometric Measurements Grade 7 2. Students solve problems involving perimeter and area.

= = =Students will understand that= •solving problems involves finding the perimeters of any polygon or circle. •solving problems involves finding areas of polygons and circles. •units are important when solving problems involving area and perimeter.

= = =Essential Questions= •Why are equations of parallelograms, regular polygons, and circles different? •What parts of a polygon or circle will help solve a problem involving area and perimeter? •How can area and perimeter of irregular polygons or combined figures be found?

= = =Students will know= •Formulas: Parallelogram- A=lw, P=2l+2w. Circle- A=(pi)r², P=2(pi)r Triangle- A=(1/2)lw, a²+b²=c². Regular polygon- A=ap. Oval- A=(pi)ab •Terminology: perimeter, regular, irregular, area, length, width, radius, apothem, circumscribed, and inscribed. •Critical Details: a polygon can be broken into squares and triangles to find area and perimeter.

= = =Students will be able to= •prove combined polygons can be broken down into triangles or squares. •illustrate possible shapes for given area and perimeters. •solve the area for any polygon or circle or any combination. •argue that units must be the same when finding area or perimeter. •consider how to find perimeter of any irregular or regular shape. •be aware of the unit of measurement.

**Performance Task Overview** Discovery's hit show, Trading Spaces: Boys vs. Girls, is looking for new kids your age to be on their show. In order to get cast in an episode next month, you must show the host, Chuck Cureau, that you and your partner have the skills. To convince Chuck, you will need to show him your design skills by presenting a Glogster of a room your team has redesigned. However, Chuck wants the best of the best, so you will need to stay on a budget of $1000 when you redesign the room with new floors, paint or wallpaper, and trim. =Expectations= As a part of the engaging curriculum, students will be spending a portion of their time working in groups as well as on projects. Activities, group work, instruction, and projects are not easily made up when a student misses class. Therefore, it is imperative for the students to make it to all classes. However, I understand that circumstances change and I expect the students to contact me if they know they will be absent so that they will know the assignments. If a student misses a class, it is his/her responsibility to find out what was missed, and create a plan with me on how and when it will be turned in. If possible, when a student is unable to come to class, they are encouraged to use Skype to know what is happening in class. All assignments will be passed in on the due date, unless otherwise discussed. If a student thinks an assignment will be late, they are encouraged to come talk to me so that we can make arrangements accordingly. Assignments must be neat, legible, and on white lined paper. Students are encouraged to show full work, so that credit may be given accordingly. Homework, in-class work, and tests may be redone until the student understands the material. Projects may only be redone if the student discusses with me the reason that he/she wants to, and what they will do differently. When assignments are redone, the student must pass in the original assignment as well as the corrected work, and it will be regraded accordingly. Plagiarism is a serious offense and will be dealt with accordingly. To prevent plagiarism, I ask students to refrain from copying directly from the internet or other resources such as books or other students. When quoting another source, or using pictures from another source, students must cite the work. The policy of the school for plagiarism is effective in this class.

=Benchmarks (100,000 points)= Students will utilize the iMovie application to enhance their learning of units of measurement. The project requires students to create a short video of where units of measurement are found in real life. This includes, but is not limited to, objects such as a tape measures and baking dishes. Students will also discuss what happens when these units are used properly and improperly for finding area and perimeter for each object. The iMovie will be no longer than 8 minutes, and no less than 5 minutes. **(12,000 points)** To display their knowledge of the breakdown of irregular polygons into regular polygons, students will create a Glogster. The Glogster will contain several irregular polygons that break down into circles, parallelograms, and regular polygons with more than four sides. The student will explain the measurements that correspond with finding the area and perimeter of the irregular polygon. To show deeper understanding, students will also be given the chance to explain corresponding angles, and how they relate to each of the regular polygons that make up the irregular polygon. **(13,000 points)** Garageband is a useful tool to create podcasts in which students can discuss any topic. For this benchmark, students will create a short news bulletin on Garageband about perimeter, regular and irregular polygons, and/or circles. Students will become newscasters as they report on a story about a company or person solving a real-life problem through using perimeter in some way. The podcast will be between 5-10 minutes in length. **(12,000 points)** To tap into the creativity of students, they will be asked to create a story of polygons. The polygons will have area or perimeter and in common, but look different. Within the story, students will explain these differences and the similarities they share as well. The ComicLife will be at least 3 pages in length. **(12,000 points)** Students will delve into real-life and explore GoogleEarth. In this application, students will use the ruler feature to find the surface area of specified buildings, such as the National Library of Belarus. This assessment will ask students to go to certain coordinates and record the perimeter, so that they may calculate the surface area. **(12,000 points)** This project (see Performance Task), will measure the knowledge the students gained throughout the unit. They will create a floor plan of each wall, ceiling, and floor of a room, and include the dimensions of the room. The students will then select paint, flooring, and trim online, and redecorate the room however they wish. The final product will be a Glogster that shows what items were used, how much each item cost, and the amount of each item purchased based on the dimensions of the room. The students will be graded on the Glogster, the floor plan, as well as their presentation. Creativity is encouraged. **(20,000 points)** Throughout the lesson, students are encouraged to participate in the activities and projects in order to get the full learning experience. Since participation is important, it has weight in the grading of this class. However, participation is easily earned if the student is engaged and interested in the lesson. Points will never be deducted because of curiosity because it is encouraged! **(11,000 points)** To ensure students are on track and not having any difficulties, they will be required to complete a daily journal entry. This entry will include what they have learned within that class, problem types they have mastered, problems they are proud of, and problems they are struggling with. The journals will be read after each day with prompt feedback. **(15,000 points)**
