  • Our geometric world: The students will use newspaper and magazine pictures to recognize geometric figures within the real world. They will make a collage of pictures showing various geometric shapes. They will write a summary of the shapes that are represented in their collage.
  • Inside, outside, and all around: Students will distinguish between perimeter, area, and volume. They will use tangrams and graph paper to create two-dimensional figures that will be measured for area and perimeter. By creating layers of centimeter cubes, the students will explore the concept of volume.
  • Investigating surface area: This is a hands on lesson best used to introduce geometry students to 3-dimensional figures. Students will have the opportunity to draw 3-dimensionally and create collapsible figures which can be used to develop the standard surface area formulas.

Learning outcomes

Students will:

  • produce an origami sculpture.
  • use the appropriate vocabulary to describe the origami sculpture and explain the sequence followed in its development.
  • solve related math problems upon completion of the sculpture.

Teacher planning

Time required for lesson

50 minutes

Materials/resources

Physical Resources

  • Paper precut to the appropriate size for the origami sculpture
  • A copy of the directions for the chosen origami sculpture (one for each student, pair, or group)
  • Paper, pencil, calculator for solving follow-up mathematics problems

Classroom Environment

  • Table space large enough for all students to fold individual sculptures
  • Computer with access to the Internet for all students

Set-up of lesson

  • Computer ready for group presentation of selected websites
  • Review vocabulary including simple fractions 1/2, 1/3, 1/4, and the geometric terms symmetry, faces, edges, triangle, rectangle
  • Paper should be arranged on a central table for easy access by all students or ready for teacher distribution.

Technology resources

  • Computer with Internet access
  • Optional: computer projector, SmartBoard, or any available mode of group Internet presentation, computer lab for individual Internet site exploration, digital camera for recording process

Pre-activities

  • The teacher should have previous experience of folding the selected origami sculpture.
  • Teacher should pre-select related websites, either bookmarking or creating a desktop folder containing these sites.
  • Optional: Read Sadako and the Thousand Paper Cranes by Eleanor Coerr prior to this math lesson.
  • Lead-in depends upon student background information; such as a discussion of the book Sadako and the Thousand Paper Cranes.
  • Students should already be familiar with simple fractions 1/2, 1/3, 1/4, and the geometric terms symmetry, faces, edges, triangle, rectangle, square, rhombus.
  • Introduce origami (an ancient Japanese art form)

Activities

Introduce Origami via Internet. (On a preceding day, I did this as a 50 minute pre-activity using a projector to provide a teacher directed overview and site exploration. Then in the same lab setting, students accessed the site on individual computers for self-exploration.)

  1. Orally review fractional parts 1/2, 1/3, 1/4, and geometric terms: symmetry, faces, edges, triangle, rectangle, square, rhombus.
  2. Distribute Origami paper and instructions (swan and shirt attached). Students may work as individuals, pairs or in small groups as best fits your class. Use the instructions for a swan or for a Hawaiian shirt.
  3. Optional: Record folding process via digital camera, still shots or video. These can be published on class/school webpage or newsletter.
  4. Forum - Have students describe the folding process using geometric terms, e.g., faces, symmetry, edges, rectangle, triangle, etc. as they apply to your chosen Origami.
  5. Solve math problems related to the projects; e.g., elapsed time, geometric shapes, lines of symmetry, cost of project, etc. These questions depend on the abilities of the students in the class and may be posted on an overhead, chalkboard, handout, or HyperStudio teacher created test stack.
  6. Open discussion follow-up - Have students discuss pros and cons of verbal, oral, pictorial directions, self-evaluate procedure and resulting sculpture.
  7. Teacher scores using rubric and math problems.

Assessment

  • Creation of an origami sculpture scored by the attached rubric.
  • Students explain the sequence of folding the sculpture (orally for my group)
  • Correct solution(s) of the follow-up math questions
