3 Rules to Spark Learning: A Must Watch for All Teachers

Ramsey Musallam, chemistry teacher from San Francisco, California, talks about 3 rules to spark learning: (1) curiosity comes first, (2) embrace the mess, (3) practice reflection. Even though he is a chemistry teacher, these rules are clearly applicable to all subjects especially mathematics. Curiosity is the reason why mathematical conjectures are made and theorems are proved. The “mess” is what every problem solver go through, it is the hidden face of cut-and-dried theorems we found in books. Reflection is important to teachers and students. They can reflect on how students think and develop strategies on how to elicit responses, while students can reflect on their practices in solving problems.

Watch Ramsey Musallam in one of the most fascinating 6-minute lectures about curiosity and learning.  Continue reading

The Explanation to the Infinite Chocolate Bar Trick

Last week, I posted about the video shown below, a method that allows you to create infinite chocolate. Watch again the video and observe closely where the extra chocolate came from.

After watching this video, watch the following video which discusses the secret behind the trick.

You can explore the GeoGebra applet shown in the second video here.

5 Cool Math Calculations You Can Do with Google Search

Search engines are used to search things on the internet. But did you know that aside from searching stuff, you can also do other things using search engines?

Google, probably the most famous search engine today, has made significant changes in it search box. Now, math calculations can be performed by directly typing mathematical expressions in its search box. Below are some of the calculations that you can do with Google search.

1.) Perform Basic Math Calculations

Google search allows you to perform basic calculations. Basic doesn’t just mean the four fundamental operations (addition, subtraction, multiplication, and division). It also includes exponentiation and modulo division. Not only that, Google search can also perform calculation using words (e.g. divide pi by 2).  Continue reading
