Is All About Math

(www.isallaboutmath.com/index.aspx)

Grades 5 and up, with parental supervision 

This website provides short instructional math videos that can be used to supplement math studies. The videos consist of a narrated lecture and animations that illustrate the concept being discussed. The videos are enabled for iPhone, iPod and iPad devices for portable, on-the-go learning.

When you get to the website you’ll see a menu of math videos that include topics such as:

  • Triangular Numbers (Parts I, II & III) – Elementary explanation of triangular numbers, a general formula for the sum of an arithmetic progression, and a solution to the Recursive equation.

  • Mathematical Induction (Parts I, II, & III) – Explains the Method of Mathematical Induction. Discussion of Francesco Maurolico, Pascal and John Wallis, plus Fermat’s Method of infinite descent, etc.

  • Weaving Numbers – Explanation of Vedic multiplication or weaving multiplication. Includes Fibonacci’s sieve or lattice multiplication, and more.

  • Dimension 2 – Explains how two numbers can describe the position of a point on a sphere, and how one can draw a picture of the Earth on a piece of paper.

  • Complex Numbers – Mathematician Adrien Douady explains the square root of negative numbers in simple terms.

  • Pi – An explanation and illustration of the most famous mathematical constant.

The narrator on some of the videos speaks in a monotone voice with an accent, so we found it necessary to really pay attention to hear and understand the lectures. Fortunately, the animated illustrations help the viewer to maintain focus.

We couldn’t find “about” information on the site, so it’s not clear who is providing the info or why. Currently, there are no advertisements on the site, and all of the videos can be accessed for free, without registration.

This is a helpful resource for supplementing the study of various math concepts.
