AMOF, the Amazing Mathematical Object Factory, shown on the left, produces lists of mathematical objects in response to customer orders. Today you are a customer and you must tell AMOF what you want produced. This factory is totally non-polluting and the objects produced are absolutely free! (There is a vicious rumour however, that the workers are underpaid and overworked.)
Try It!
Click on a icon with an Indigo background, such as , to learn about that object, or on an icon with a Green background, such as to generate the object. Get it? Indigo = Information, Green = Generate; the first letters are the same! To get back to this page click on the AMOF icon , which appears both at the top and at the bottom of all succeeding pages. In addition, the SchoolNet icon appears on every page as well; clicking on it will take you back to the SchoolNet home page.
What is a Combinatorial Object?
Combinatorial Objects and Discrete Mathematics
Discrete mathematics is that branch of mathematics that studies combinatorial objects. This is an area of mathematics of increasing importance in todays world. It is the mathematics that underlies computers and tele-communication. There is a recent and growing trend towards more discrete mathematics in the K-12 math curriculum. Discrete mathematics became a required part of study for mathematics majors in universities by 1980, and it was soon recommended that ideas of discrete mathematics should be developed earlier in the mathematics curriculum. Inclusion of discrete mathematics in all school mathematics programs received the necessary impetus for serious consideration in 1989 with the inclusion of the topic as one of the secondary-level standards in the NCTM's Curriculum and Evaluation Standards for School Mathematics. The NCTM (National Council of Teachers of Mathematics) has since published a book, Discrete Mathematics Across the Curriculum K-12, that contains much material about discrete mathematics and its uses in the curriculum. We'll refer to this book in some of the information pages. Whenever you see [NCTM], we're referring to this book. Another book published by NCTM, Readings for Enrichment in Secondary School Mathematics, contains material on permutations, sets, Pascal's triangle, and other topics used by AMOF. The book Mathematical Activities: A Resource Book for Teachers by the popular author Brian Bolt contains useful material on Pentominoes, Pascal's triangle and many other topics of discrete mathematics.Here is a list of some sites relevant to discrete mathematics education K-12.
- Colorful Mathematics; PC games involving mathematical structures known as graphs; from the University of Calgary.
- Mega-Mathematics; a collection of discrete mathematics activities geared towards a young audience.
- Math Forum's Discrete Math Page
- University of Colorado's Discrete Math Project (DMP)
- Discrete Math in the Classroom; a resource for teachers about the definition of and goals of discrete mathematics in education.
- DIMACS Leadership Program in Discrete Mathematics K-8.
- MacTutor's Mathematical games and recreations, most of which are discrete mathematical in nature.
What is the Combinatorial Object Server?
The (Combinatorial) Object Server (COS) is a WWW site which has the ability to generate (i.e., list) many additional types of combinatorial objects besides those found on AMOF. COS is oriented more towards University students and researchers. However, the ideas behind AMOF (and originally, ECOS) are derived from COS.
