Mathematical Posters 

These posters are as beautiful as they are informative. There are 22. Due to special packaging costs ($5), we recommend that you purchase at least 3 or more at a time. Of course we will ship a single if you wish. $10.00 Each 

Aspects of Infinity
A fascinating display. 15 different “aspects” of infinity, all clearly presented. Much food for thought. For further exploration of the subject, look at "Images of Infinity" by the Leapfrog Group, and "Keys to Infinity" by Clifford Pickover.



Euler's Theorem
Leonhard Euler (Oyler), (17071783)
A Swiss mathematician who went blind at a relatively early age. He made great contributions to: numerical analysis, calculus, and topology. Much of our mathematical notation that we use today developed from Euler’s work. For example: popularizing the Greek letter pi for the ratio of the circumference to the diameter of a circle: using the lower case letters a, b, and c to represent the sides of a triangle. At his death, it took 50 pages just to list the titles of his works.
Euler’s Theorem: He discovered that for certain solids, F+V=E+2 or F+VE=2 where
F=the number of faces
V=the number of vertices
E=the number of edges
For further exploration, "Mathematicians are People Too – Volume 1" is an excellent reference.



Exploring the Triangle
A picture is worth 100 words, as the saying goes. This poster says it all.



Factors Primes and Pairs
Using color, factors, primes and pairs are readily visible. The table at the bottom clarifies even further.



Fermat's Last Theorem
Pierre de Fermat (16011685). A French lawyer for whom mathematics was a hobby. He is the founder of modern number theory and contributed to the development of analytic geometry, calculus, ands probability. He is most famous for his last theorem, scribbled in the margin of a book. The proof was completed only recently by Professor Wiles.
For further exploration on Fermat, “Mathematicians are People Too – Volume 2” is an excellent reference. For further exploration on the proof, there are three readable books under Mathematical Principles



Fibonacci Numbers
Leonard of Pisa or Fibonacci (c.11801250 Fibonacci means Son of Bonacci). An Italian mathematician, he popularized the use of Hinduarabic numbers: 1,2,3,4,5,6,7,8,9 plus the sign 0. . He worked in algebra and geometry and introduced the Fibonacci sequence where each number is the sum of the two previous numbers. In the 19th century, scientists began to discover the presence of the sequence in nature. For further exploration about Fibonacci, “Mathematicians are People Too – Volume 2” is an excellent reference.

Fractions & Decimal Equivalents
A handy presentation of number facts we need to know.



Golden Ratio
More presentations of the ubiquitous Fibonacci numbers.



Impossible Geometry (Escher type figures)
Real or unreal. These figures are visual conundrums. The eye goes round and round. These figures can be imagined or drawn but cannot be created in concrete form. They all are impossible figures.
For further exploration, “Adventures with Impossible Figures” is an excellent reference. It explains how you can create these visual conundrums.



Knots Mathematics
Knots are both useful and beautiful. Ask any macramé artist. Mathematicians study them as a branch of topology.
What is topology? It is the study of the detailed mapping or charting of the physical features of an area.
(What is topography? The representation of 3dimensions in 2dimensions.)



Multiples (100 squares for multpiples 112)
A handy way to review multiples from 1 to 12. By using the 100 square, students can spot their errors at once since the pattern gets broken if the answer coloredin is incorrect.



Nets and Solids – From 2D to 3D
How many sides to a cube? This colorful pictorial depiction of various multisided figures makes it easy to determine.



Number Patterns
Yes! Besides the interesting Fibonacci number sequence, there are many other interesting facts about numbers. This should be hung at eye level for easy reading.



Pascal's Triangle
Blaise Pascal (16231662) A French thinker and scientist who made invaluable contributions to mathematics and physics. In the layout of the triangle, he found pattern after pattern. He built the first calculator. He worked with Fermat and developed probability theory.
For further exploration, "Mathematicians are People Too – Volume 1" is an excellent reference.



A Piece of pi
Five 10" x 60" sections combine to form a 25 foot "approximation" of pi, accurate to more than 70 places.

Polyhedra
Again, a picture is worth a 1000 words.



Prime Numbers to 12,000
A handy reference.



Reflections & Rotations – 2 kinds of symmetry
An excellent presentation showing two ways of achieving iteration. Symmetry has an inbred appeal. It is always nice when things balance.



Sliceforms Surfaces
These are the end result of an interesting craft activity. There is an instruction book, Slice Forms, that contains samples to cut out and assemble. Each piece will fold flat for storage just like the partitions in a case of bottles.



Spirals and Helices
Presentations of curves developed from Fibonacci numbers both in nature and manmade. All helices are spirals but all spirals are not helices.



Theorem of Pythagoras
(Born c.560; died c. 480 B.C.) A notable Greek philosopher who made important contributions to the development of mathematics, astronomy, and music theory. He is best known for the theorem that bears his name. In a right triangle. The square of the hypotenuse is equal to the sum of the squares of the other two sides. Or a^{2} + b^{2}= c^{2}.
For further exploration about Pythagoras,"Mathematicians are People Too – Volume 1" is an excellent reference.



Which Number Comes Next?
A puzzle to solve and an inspiration to create other number sequences.



Who Did It? Puzzle
The best fun. A group of logic problems. We have had several groups in the store pondering the solution. We also carry the book that addresses this type of problem.
For further exploration, “Who Tells the Truth?” is an excellent reference.
