Students use Geometer’s Sketchpad here to construct geometric shapes


Computers & Internet, Math  



Title – Geometer’s Sketchpad
By – Kelly F.
Primary Subject – Math
Secondary Subjects – Computers / Internet
Grade Level – 7


  • The students will use Geometer’s Sketchpad to construct geometric shapes.


  • G.SR.07.01 – Draw and construct geometric objects.
    Use ruler and other tools to draw squares, rectangles, triangles, and parallelograms with specified dimensions.

Learning Resources and Materials:

  • Computer
  • Geometer’s Sketchpad (software)
  • Geometric shapes handout
  • Pencils

Development of Lesson:

  • Introduction:
    • Before getting the students linked to Geometer’s Sketchpad, explain and go over what the different geometric shapes are and what defines them.
    • Explain that there are several ways to go about constructing shapes.
    • Explain that they will use Geometer’s Sketchpad software to construct the shapes.
  • Methods/Procedures:
    1. The students will log onto Geometer’s Sketchpad.
    2. The students will be given a worksheet with the different geometric shapes that they are to construct. They will have different dimensions that they are to incorporate into their shapes. Each student will have different shapes to construct.
    3. The students will be given the freedom to make the shapes their own (adding colors, etc.).
  • Accommodations/Adaptations:
    • The students will be given geometric shapes that vary in difficulty depending on their skill level.
  • Assessment/Evaluation:
    • The students will be evaluated based on their handout. The students will be graded based on if they constructed the correct shapes in the correct way.
    • A test will be given at the end of the unit to assess the students’ knowledge on geometric shapes.
  • Closure:
      The students and the teacher will have a discussion about geometric shapes.

      • Where are the different shapes found in the environment?
      • They will discuss what their thoughts were about Geometer’s Sketchpad.
      • What could be done differently?
      • What could be done to make this more fun?
      • Did the students enjoy this activity?

Teacher Reflection:

  • The teacher will reflect on the discussion as well as the handouts completed by each student. This may help the teacher to make changes in the future.
