Homeschool Information Library HEM's Information Library Index Older Homeschoolers Index Rethinking Midschool/High School Math From the Older Kids column, by Cafi Cohen, originally published in the January-February 1997 issue of Home Education Magazine. M-A-T-H. What thoughts come to mind with the word MATH? One of the three R's. A government school "required subject," according to many state statutes and some local regulations. An essential topic in any homeschool. Past that point, what official guidance are you given for teaching math? Often, none. What you cover and how you cover it is up to you. In the absence of specific directions, many homeschooling families pursue what I call School Math. School Math is how most parents studied math when they attended school; and it is how most schools still teach math. School Math involves textbooks, workbooks, and exams. Older kids pursuing School Math study the subject sequentially in other words, arithmetic, followed by algebra, then geometry, second year algebra, trigonometry, and so on. Those using a School Math program must always "show all the steps" and reason exactly like the author of the text reasons. Alternate approaches to problem solving are unacceptable. Getting the right answer is emphasized, often to the exclusion of understanding the process. School Math texts often include unrealistic problems. Typical is the following. A 20-ft. telephone pole falls across a street and the two ends extend one foot and three feet either side of the street. How wide is the street?

MARCH 6, 2003 VOLUME 33 NUMBER 21 Professor has a few tricks to make math fun Recreational mathematics. Although the term seems like a classic oxymoron, it is actually a class here at Temple. Designed to get people thinking about the magic of math, the course is taught by a handful of professors, including one who knows the trick to making math fun. The competition, sponsored by the actuarial science program in the risk, insurance and healthcare management department of the Fox School of Business and Management, pitted 11 area high schools in a series of math events. Winning was secondary to encouraging an interest in mathematics. And, if a trick or two could be used to advance the cause, then Chein was up for the task. Problem Solving through Recreational Mathematics with Bonnie Averbach, an actuarial science professor at Temple. An avid fan of logic and math puzzles, Chein began toying with the idea of creating a course on recreational mathematics in the early 1970s. As quickly as you can say presto chango, the class was born. It is now offered once a year and has many faculty members vying to teach the class.

Sir Roger Penrose Recreational Mathematics? That's right - recreational math; the passion of Sir Roger Penrose who was recently knighted for his outstanding contributions to mathematics. Roger Penrose, a professor of mathematics at the University of Oxford in England, pursues an active interest in recreational math which he shared with his father. While most of his work pertains to relativity theory and quantum physics, he is fascinated with a field of geometry known as tessellation, the covering of a surface with tiles of prescribed shapes. Penrose received his Ph.D. at Cambridge in algebraic geometry. While there, he began playing around with what appears to be a somewhat frivolous geometrical puzzle. He wanted to cover a flat surface with tiles so that there were no gaps and no overlaps. There are several shapes that will do the job, regular triangles, rectangles, hexagons, and so forth. Or it can be done with combinations of shapes, resulting in a pattern that repeats regularly. Penrose began to work on the problem of whether a set of shapes could be found which would tile a surface but without generating a repeating pattern (known as quasi-symmetry). It turned out this was a problem that couldn't be solved computationally. So, armed with only a notebook and pencil, Penrose set about developing sets of tiles that produce 'quasi-periodic' patterns; at first glance the pattern seems to repeat regularly, but on closer examination you find it is not quite so.

Concentrations in the mathematical sciences prepare students for a wide variety of careers requiring problem solving, logical reasoning, and applications of current technologies. The mathematics program at Huntington combines the individual attention normally associated with small liberal arts colleges with the educational opportunities and research-active faculty normally found only at major universities. The Mathematics Department offers Bachelor of Arts, Bachelor of Science in Science, and Bachelor of Science in education degrees. Computer science is a new and fast growing field compared to most disciplines. As such, the key to an effective computer science program is the ability to provide a solid foundation in the fundamentals of computer science while also offering the flexibility to explore the latest innovations in current technologies and programming. Huntington's program strives to provide this balance by providing a solid foundation in fundamental programming using multiple current programming languages. Students build upon their programming foundation by pursuing topics of interest through a variety of projects that strive to provide the most current applications of technology in use today. Huntington offers both a major and a minor in computer science as well as the new management information systems minor which integrates both business and computer science.
