THEME :Geometry is Real

BROAD CONCEPT:Team work,project building, presentation skills,transfer of school to real life

GRADES:7-9 geometry

INTEGRATED SUBJECTS: math, science, language arts,technology, art

UNIT GOALS AND PURPOSE; 

The purpose of this project is for the students to work as a team to use internet resources in order to make connections between two- and three dimensional shapes and the real world.  They will be given opportunities to explore their own world and the world of the internet.  The students will develop new ideas and understandings while working with others.  Students will analyze characteristics and properties of two- and three-dimensional geometric shapes to visualize and solve problems such as those involving surface area and volume.   Students will use a spreadsheet to display information and KidPix Deluxe Studio to present their slide show  on geometric solids.  In  completing the house project on home improvement the students will have solved problems in, and gained insights into, other disciplines and other areas of interest such as art and architecture. 

The unit will be evaluated in an ongoing manner by the teacher since every class has an activity that allows the teacher to monitor student work.  In regards to evaluation, the unit is also performance-based since the students will be completing many authentic tasks.  With the open-ended culminating project, the unit will also be evaluated in a  summative manner.

STUDENT ACTIVITIES WHICH WILL PROMOTE ENGAGED LEARNING
               

Lesson 1. Brainstorm
The class will open with a PowerPoint presentation showing  triangles, quadrilaterals,and circles and their area formulas.  Students will be introduced to the unit Geometry Around Us.  We will then brainstorm using Inspiration as an entire class on all the facts that the students may know about three dimensional objects (e.g.,prisms, pyramids, cones, cyllinders and spheres) and their surface area and volume.  We will use a KWL/KWLH  Chart as a graphic organizer to help students develop orgnizational skills for this and other research projects.  To relate this lesson to the real world, students will be expected to find an example of each kind of three-dimensional solid at home and be prepared to share their findings with the class.  These examples will include pictures, photos(using a digital camera) or actual objects of each solid.

Lesson 2.  Sharing and research
After a discussion about the three-dimensional solids students found at home, the class will go to the computer and work in groups to discover examples of three-dimensional solids in everyday life, science, nature, business and art.  Each group will use Inspiration  to organize their findings.  The groups will supplement their  Inspiration webs on three-dimensional solids, so that each solid has two or more real world examples.  Use internet sites such as  Images/google.com.or http://multimedia.lycos.com/

Lesson 3 & 4.  Research and Slide Show
Using the initial KWL Chart, internet sites, Websters Dictionary, MS Encarta, and World Book Encyclopedia, each group will record definitions, surface area and volume formulas for each three-dimensional solid using MS Word.  Further research will include finding graphics for each geometric solid.  Use internet sites such as http://www.webmath.com/geo_cylinder.html ,and http://www.webmath.com/index5.html .
Each group will produce a slide show presenting this information using KidPix Deluxe, PowerPoint or Hyperstudio.  The slide show will contain at least two slides for each geometric solid with definitions,surface area and volume formulas, illustrations and graphics of real world occurrences of these geometric solids.   Each group will present their slide show to the class.

Lesson 5. Cereal box
This activity will provide a tangible example of deriving the formula for the surface area of a rectangular solid.  The students will be assigned to cooperative groups.  Each group will be equipped with a cereal box, scissors,rulers, and colored markers.  The students will be instructed to produce a net for the cereal box in scale using MS Excel, shade congruent faces the same color, write the area on each face, then find the total surface area.  Each group will generalize how to find the surface area(use variables instead of numbers).  Groups will share to see if their generalization works on the neighbor's box or on any box.  Each group will report to the class what they have discovered about their cereal box, explaining how they came to their conclusions.   The connection of this formula to the House project will be discussed.

Lesson 6.  Volume  and Space
This lesson involves activities using the volume and surface area formulas for geometric solids.  The students will work in pairs.  For activity one, the students are given the dimensions of a swimming pool and asked to determine its volume, how much water it contains and how much that amount of water weighs.  Students will use MS Word and MS Excel to record results and computations for each activity.  For activity two titled
We Have Liftoff:Math and the Space Program, the students, using the Manned Space Program Data Sheet , will answer questions involving volume of the cone-shaped capsules and how much space was allowed for each person on the Mercury, Gemini, and Apollo missions.  For activity three titled The Capacity of  the Planets, the students, using a chart listing the planets and their diameters, will answer questions about their volumes and surface areas.  Data sheets and suggested questions can be found at these sites http://www.pbs.org/teachersource/mathline/concepts/space2/activity3.shtm and
http://www.pbs.org/teachersource/mathline/concepts/space/activity1.shtm

Lesson 7. Research for the House Project.
Students will begin the house project in this lesson.  Working in pairs, the students will visit internet sites like
http://www.dreamhomesource.com/and  http://www.design-house.com/
The project requires a blueprint of a 3-bedroom house, ads for carpet, tile, interior house paint , fertilizer and an airconditioner.  If ads cannot be found on the internet, they can be scanned from newspapers or brochures.  The students could also visit local stores and take pictures with a digital camera of these items and their prices.  This data will be included in the final presentation using KidPix,Hyperstudio or PowerPoint.

Lessons 8&9.  Dimensions and Cost
Students will use MS Excel to determine areas, volumes and costs for the project.  Students will enter the dimensions of the 3 bedrooms and livingroom into MS Excel.  They will determine the area of each room in square feet and square yards.  Using the carpet ad, they will determine the cost of carpet. Students will enter the dimensions of the kitchen and bathroom(s) and find the area in square feet.  Using the tile ad , they will determine the cost of tile (no partial tiles purchased).  Using the dimensions of the three bedrooms, the students will determine the ceiling and wall areas in square feet (assuming  walls are 8 ft. high).  Using the paint ad, the students will determine the cost of  paint (applying  3 coats).  Assuming the lawn extends 50 feet from the house in each direction, determine the lawn area in square feet.  Using the fertilizer ad, the students will determine the cost of fertilizer.  Using the dimensions of the recorded rooms, the students will determine the volume in cubic feet and the cost of the airconditioner indicating how many tons are needed.

Lesson 10.  Total Costs and Show
Students will complete their house projects.  Students will use MS Excel to determine and record the total cost for carpet, tile, paint, fertilizer and airconditioner.  The house project will be presented in a slide show  using KidPix, PowerPoint or Hyperstudio.
The presentation will contain blueprints, ads, spreadsheets indicating their results for area,volume and costs as well as a written explanation of all calculations and costs using MS Word.   Additional activities would include preparing a sign of a brochure using Print Shop advertizing their chosen house plan  and illustrating their materials for their home improvement.

SHARE YOUR IDEAS:

Students will present their final project to the class.  The culminating project for the unit will be a  multimedia presentation to the class as well as a written explanation of all calculations in the project to the teacher.  The rubric for the activity is as follows:

STUDENT AND TEACHER ROLES:
Students will lead much of their own work because they will be working together.  The tasks are authentic, challenging, and multi-disciplinary. The students have the opportunity to be explorers.  The students become the teachers for their small groups and the class as a whole.  Students become producers in that they develop products of use.  The teacher is a facilitator of learning by creating well-developed lessons that have a problem-solving aspect to them.  The teacher will also facilitate group set-up by ensuring that groups are flexible and heterogeneous.   The teacher is a guide by modeling different concepts for the students.  The teacher supports the students' journey through the unit by giving feedback based on student need.  Whole class discussions as well as group work facilitate learning.  The teacher focuses not controls student learning.  Finally, the teacher is a co-learner.  Many activities require the teacher to adapt  and modify the unit to meet students' needs.
