Sample Classroom Procedure / Teacher Instruction

  1. Display several triangles. Ask students to tell you everything they know about triangles.
  2. Allow for responses and discussion. Ask students to compare/contrast the displayed triangles.
  3. List the likeness and differences students can identify. Introduce triangles.
  4. Distribute Triangles (4-6) content pages. Read and review the information with the students. Allow students to share examples of combined examples of triangle types. Save the final question for the lesson closing. Use the additional resources to enhance understanding.
  5. Distribute Activity page. Read and review the instructions. Distribute supplies. Encourage students to be creative. The size of each drawing will depend on each teacher’s preference.
  6. Distribute Practice page. Check and review the students’ responses.
  7. Distribute the Homework page. The next day, allow students to share their drawings or photos. Each must identify and describe the triangle shown in the drawing or photo. Collect and check remaining work.
  8. In closing, ask: Which of the triangle types would best represent you? Why?
  9. Allow for responses and discussion. (For example, an equilateral may be chosen by a student who has a neatly organized desk or locker.)
