To those who want to be rich, lottery might be the answer, but before buying a lottery ticket, maybe you should read James Pollock’s article on Winning the Lottery.
Bill James proposes an Alternative Math Methods of multiplications by using lattices in his blog Discrete Ideas.
Understanding is about making connection. This was Erlina Ronda‘s introductory statement as she explains the advantages of using mathematical investigation in the classroom in her article, Making connections Through Mathematical Investigation Part I and Part II. Ms. Ronda enriches her discussion by giving sample activities and GeoGebra applets in the said articles.
David Wees shares a brilliant idea in developing higher order thinking skills among students through problem posing. He let his students formulate problems and turn their math problems into math video problems. He has some examples of the video outputs in his blog.
David Pilarski connects mathematics to art in his articleArt Meets Geometry – Two Point Perspective Drawing. Mr. Pi, as he would like to call himself, has lot of high school mathematics tutorial videos in his blog.
John Golden gives us excellent teaching ideas on introducing variables using GeoGebra in his article GeoGebra: variable posted at MathHombre. Aside from the applets, you can also download several of his files.
Michelle R. Davis writes about the experiences of students in North Carolina on solving algebra problems using smart phones. If you’re new to technology, you may want to check out Richard Byrnes shares with us Twelve Essentials for Technology Integration.
Eric Weiss shares with us the Google tools that we can use in learning and teaching in his article 25 Little-known Google Tools for Scholars and Academics.
Alexander Bogomolny tempts us in his his chocolate and mathematics post Technology and Red Herrings at CTK Insights. The task is to break rectangular chocolates along its “fault lines” with minimal number of “break up operations.”
