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 http://mathforum.org/pubs/boxer/tess.html http://mathforum.org/pubs/boxer/student.tess.html A teacher lesson plan and student page written to help students understand why equilateral triangles, squares, and regular hexagons tessellate regularly in the Euclidean plane.

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: http://nces.ed.gov/nceskids/probability/ Roll the dice to generate data and a graph. -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- JON BASDEN'S MATHEMATICS LESSONS http://mathforum.org/te/exchange/hosted/basden/ 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. http://mathforum.org/te/exchange/hosted/basden/pi_3_14159265358.html The Area of a Parallelogram Students learn to calculate the area of a parallelogram. http://mathforum.org/te/exchange/hosted/basden/llgramarea.html The Right Time Students learn the angles that the hands of a clock make. http://mathforum.org/te/exchange/hosted/basden/clock1.html The Area of a Circle Students derive the formula for finding the area of a circle. http://mathforum.org/te/exchange/hosted/basden/circle_area/circle_area.html \|/ TEACHER EXCHANGE http://mathforum.org/te/ If you have a lesson idea that you would like to contribute to the Math Forum @ Drexel site, please visit the Teacher Exchange area of our site. -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- CHECK OUT OUR WEB SITE: The Math Forum http://mathforum.org/ Ask Dr. Math http://mathforum.org/dr.math/ Problems of the Week http://mathforum.org/pow/ Mathematics Library http://mathforum.org/library/ Teacher2Teacher http://mathforum.org/t2t/ Discussion Groups http://mathforum.org/discussions/ Join the Math Forum http://mathforum.org/join.forum.html Send comments to the Math Forum Internet Newsletter editors _o \o_ __| \ / |__ o _ o/ \o/ __|- __/ \__/o \o | o/ o/__/ /\ /| | \ \ / \ / \ /o\ / \ / \ / | / \ / \ ```
