Math Education and Fun with Geometry Guy aka Don R. Mueller, Ph.D.

1. The Geometry Guy Show
Geometry
Guy
With your Host

2. In addition to the Geometry Guy Show,
Don has taught a number of college math courses:
▪ College Algebra
▪ Linear Analysis
▪ Quantitative Math
▪ Calculus I, II
▪ Developmental Math
(algebra & trigonometry)
▪ Computers in Science

3. The Geometry Guy Show is a hands-on
math course for kids featuring fun and exciting
uses for math in everyday life, science, art,
business, sports and other interesting areas.
Geometry Guy has many years of experience
showing kids that math concepts and
principles are really easier to understand than
they generally think.
This is a highly interactive show with many
thought-provoking applications of math. Come
join the fun!

4. The Geometry Guy Math Education Show
features hands-on math demonstrations
along with math jokes, rhymes, riddles,
puzzles & stories. So much fun, so little time.
“What’s your angle?” asked the circle of the triangle.

Shape

6. A trip around the Circle is sure to please.
Each time around any good old circle is
three hundred and sixty degrees: 360°
The Square is a very useful shape,
Having four sides of equal measure.
With each angle like the other three,
The square truly is a treasure.
“Give me Five.” said the Pentagon.
Five sides and five angles will do.
One for the bottom, two for the sides
and two for the top:
Thank you.

7. The Isosceles Triangle has a funny name.
It has three sides like other triangles,
But now, Two sides are the same.
The Equilateral Triangle,
has all three sides the same.
Since each angle, is like the other two,
Equi-angular is also its name.
Isosceles
A triangle with three sides of
different length, is really rather keen,
It’s not Equilateral or Isosceles,
But instead it’s called Scalene.
Equilateral
Scalene

8. Right Triangle
The Right Triangle is a special one,
Of great importance, near and far.
The Right Angle, is opposite the
Hypotenuse and called Perpendicular.
Mighty is geometry; joined with art, resistless.
− Euripides. 480? - 406 BC

9. The Triangle expert was sometimes acute, and
occasionally obtuse, but always right when it came
to having fun with triangles. You can too.
H. R. Jacobs, Geometry, 3rd edition, W. H. Freeman & Co., 2003

10. To add fun and excitement to math education,
Geometry Guy has created the GeomeTroids
“The Friendly GeomeToys.” From simple
geometry, the GeomeTroids come to life:

new geometric characters and the symbol Pi:

43. For those geometers with a “sweet tooth”
Geometry Guy has created Silly Shapes lollipops.

44. Silly Shapes “Geometry Pops” Lollipops
Eight different shapes with silly faces.

45. As one mother said: “My daughter has a pretty
firm grasp on what a circle, triangle, square,
rectangle and oval look like. However, when
she gets into more diverse shapes such as
hexagons and octagons…well, she starts to
have some trouble with them.
Thanks to Silly Shapes Lollipops, she’s now
learning shapes and enjoying them: Yum! Yum!
Who knew Math could be Fun and Delicious?!!

46. Geometry Guy also gives workshops on
building Geometry Toys from simple materials.

ask questions such as: “What is the geometry of the
Universe?”
