Constructing Geometrical Figures to Scale

This lesson shows how to use tactile graphics to construct geometric figures to scale with students who are blind or visually impaired.

Student will use tactile graphics to compute area of given shapes and create scale replicas.

  1. Give student tactile shape.
  2. Using the squares on the graph paper, have the student calculate area.
  3. Discuss “scale” and give tactile examples of various shapes (not only geometric shapes).
  4. Have the student use graphic art tape to create a scale replica of the original shape.
  5. Use the squares to calculate the area of the new shape.
  6. Compare areas of the shapes in relation to scale.
