  1. Projects in Mathematics Adaptable For All Classes Presented by: Marianne Ilmanen Joe Henderson

  2. Why Projects ? • Projects give students a longer period of time to solve a problem than is available in a class period. • Projects allow students to deepen their understanding of math with hands-on, problem-solving activities. • Projects help to improve student reasoning, problem-solving, communication and make math connections to real world situations • Projects can be done in groups that require students to contribute to a group effort and to accept group consensus.

  3. Sample Projects • Projects that Incorporate Literacy into Mathematics: Career Investigation • In Class Group Projects: Review for Final Exam • Research Projects: Standardized Test Question Analysis • Real World Topics that Reinforce the curriculum: Recipe for MathPyramid PowerMapping Distance in a Plane • Projects Adapted for Different Course Levels: Function Families Volume of a Box

  4. Career Investigations Project Project Description: Students investigate a career that has strong mathematics base from a list of careers. - Students are given a list of careers that have a mathematics base, a set of questions to be addressed and the project grading rubric. • - Students choose a career from the Career List. • - Students research their chosen career using www.bridges.com at the career center or at home.

  5. Career Project Questions • What are the duties of the career? • What academic path is required for the career? • What math classes do you need to take during your education to prepare for this career? • How is math important for this career? • Which schools have respected programs in this field? • Are there jobs available in this career in your area?

  7. Rubric

  8. Final Exam Review Project Description: Students identify the maintopics that are covered on the final exam, using post-it tabs.

  9. Linear Equations X and Y intercepts Slope Slope-intercept form Point-slope form Standard form Labeled Graph Final Exam Review Project Directions • Provide a sheet of butcher paper for each general topic. • Title each sheet with a topic. You may add any key questions that you want addressed.

  10. 3. Pre-select groups of 4 students for each group. • Arrange your room into clusters of four desks. Place a poster on each table and assign a group to each. WARNING DO NOT let the students pick their own groups! • Give each group a different color marker so that their contributions to each poster can be identified.

  11. 6. Have the groups rotate to each poster at one minute intervals. • At each stop, the group will provide the definition of one item on the poster. They can write out a definition or draw a picture with labels. Each group should havea person assigned to each of the following job assignments: • One writer/recorder • Two journal researchers • One person to check for accuracy

  12. Example of Rotation

  13. When the groups have rotated through all of the stations, they are assigned to check and edit the poster at their last station. • Each student is given a copy of the Review Outline. • 10. Each group presents their posters while the other students complete their individual outlines.

  14. Standardized Test Question Analysis Project Purpose: To allow students to assess their own math knowledge, to determine if the test is trying to confuse them in the question or with the answers and to discover if the answers contain any “boobie traps”.

  15. Preparation: • Select a set of standardized test questions, so that each student will have a unique question. • Prepare a large scale version of the questions for use on the overhead projector or for use in power point. • Give each student one of the selected standardized test questions and a copy of the rubric.

  16. Independent Student Work Students answer a set of questionsabout their multiple choice problem. Students type their answers in paragraph form…or make a poster. Students present their answers in class to the other students.

  17. Activities and Questions • Draw a diagram or picture. • What math knowledge do you have to have to answer the question? • How are they trying to confuse you in the question? • Show your work and answer the math question. • How are they trying to confuse • you with the answers? • 6. Which answers are “boobie traps” ?

  18. Rubric

  19. Recipe for Math Project Project Description: Using the recipe for HERSHEY'S "PERFECTLY CHOCOLATE" CHOCOLATE CHIP COOKIES, students will find algebraic relationships of the ingredients.

  20. Student Investigations 1. Students write an equation relating the number of cups of brown sugar (S) to the number of cups of flour (F ) in the cookie recipe. Using their equation, students determine the amount of flour or brown sugar would be needed in different situations: For a double recipe of cookies   For a recipe that increases the amount of flour For a recipe that increases the amount of brown sugar

  21. Using a Graph 2. Students graph the equation relating the amount of brown sugar to the amount of flour and use the graph to answer these questions: - How much brown sugar will be needed if 10 cups of flour are used. - How much flour will be needed if 6 cups of brown sugar are used.

  22. Making Connections Students are asked to re-write the cookie recipe for a bakery that makes 24 dozen cookies in each batch.

  23. Pyramid Project Project Description: Students will make a scale model of the Great Pyramid of Khufu. From the scale model, they will determine estimates of the actual measures.

  24. Model • Using the pattern provided, each student creates a scale model of the Great Pyramid • 2. Given the scale of the model, students determine the actual measurements of the Great Pyramid. • 3. Students determine the slope of each face of the Great Pyramid from the measurements.

  25. Making Connections 4. Students draw a representation of the Great Pyramid on a coordinate System, determinethe coordinates of the cornersand the slope of the edge of the face. 5. Students construct their own scale models of the other two pyramids of the Giza Plateau, Khafre and Menkaure.

  26. Distance on a Plane Project Description: Using maps of Sacramento and Long Beach, students investigate different ways to determine the distances between different landmarks.

  27. Sacramento Students investigate the drivable distance and direct distance between different buildings

  28. Long Beach Students use a map of Long Beach with a coordinate grid to investigate relationships of lines that connect schools.
