        Create a Graph | Jon Basden's Mathematics Lessons

      - Archived Math Lesson

  This introductory lesson, viewed best using Internet Explorer,
  provides a tutorial to learn which regular polygons
  tessellate the plane. Museum articles illustrate where
  tessellations appear in the fine arts. The tessellation
  tool, a Java applet, can be used to experiment with creating
  your own tessellations online.

            REGULAR TESSELLATIONS - Suzanne Alejandre


  A teacher lesson plan and student page written to help
  students understand why equilateral triangles, squares,
  and regular hexagons tessellate regularly in the Euclidean

                        CREATE A GRAPH


  An interactive tool for creating area graphs, bar graphs,
  horizontal bar graphs, line graphs, and pie charts. After
  selecting one of the types of graphs, there is an explanation
  to help the user decide if this is the correct graph for the
  given data.

  After confirming the choice of graph, choose:

    - the graph size (small, medium, or large)
    - to make a 3D graph or not
    - the area color 
    - the background color
    - the image file type

  Students can see how graphs can be used in probability by
  going to this page:


  Roll the dice to generate data and a graph.



  Jon Basden has contributed four middle school lessons to the
  Math Forum's Teacher Exchange:

  Derivation of Pi
    Students use real-world objects to understand the concept
    of a constant such as Pi.

  The Area of a Parallelogram
    Students learn to calculate the area of a parallelogram.

  The Right Time
    Students learn the angles that the hands of a clock make.

  The Area of a Circle
    Students derive the formula for finding the area of a circle.
