Announcement: GeoGebra Seminar Batch 2 in August

Announcements, GeoGebra, Miscellaneous

I would like to invite all high school and college mathematics teachers to attend the 3-day GeoGebra Level 1 Seminar-workshop which will be conducted on August 6, 13, 20, 2011 (Saturdays) in UP NISMED, UP Diliman.

This training is designed to equip the participants with the basics of GeoGebra, the skill to create dynamic applets, and strategies on how to integrate GeoGebra in teaching mathematics. Uploading GeoGebra in blogs and wikis, particularly in the GeoGebra Institute of Manila wiki, will also be discussed (this was not included in Batch 1).

Note: Each participant is required to bring his/her own laptop.

For more details, click here. If you have questions, please read the training’s Frequently Asked Questions (FAQs).

Simon’s Favorite Factoring Trick

High School Algebra, Problem Solving and Proofs

Hmmm... I didn't know Simon was that good in math.

When I was quite younger, one of my hobbies was joining internet forums (fora?) on problem solving. I was not really good at it, so my role was only to ask questions. One of the internet forums I joined was the Art of Problem Solving math forum.

Art of Problem Solving (AOPS) is a community of problem solvers dedicated for math competitions – probably the best place on the web to ask hard (and very hard)  math questions. One of the tricks I learned there was Simon’s Favorite Factoring Trick (SFFT), a factorization technique popularized by one AOPS member. The general strategy (see example 3)  of SFFT is to add a constant or variable to an expression to make it factorable. This strategy can also be named as “completing rectangle” in analogy with “completing the square.”  » Read more
