Mathematics and Multimedia Blog Carnival #1


Welcome to the Mathematics and Multimedia Blog Carnival Number 1. Before beginning, let us see what’s so special about 1 as a number.

is a homophone of Juan (dela Cruz), the person who represents the Filipino people.  He is just like Uncle Sam of the United States. Hmmm… just a thought, should we change Juan dela Cruz to Manny Pacquiao?

is the multiplicative identity. Any number multiplied by 1 is equal to that number.

is the only number that is not prime nor composite.

is the number in French playing cards intead of Ace. It is the international dialing code for the United States and Canada.


is equal to 1/21 + 1/22 + 1/23 + 1/24 + 1/25 + …

is equal to sin2 (a) + cos2 (a)

is equal to | Fn x Fn+3 – Fn+1 x Fn+2 | (F = Fibonacci numbers)

One is said to be a lonely number.  If you are as lonely as the number one, maybe reading the blog submissions below will be of great help.

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.

Heather Sanders shares with us about the difficulties in distance learning, and gaining solutions from different 7  free  web applications from the internet at CNA Class Online .

Mr Robbo has an excellent idea on how to run a 3d maths test in Google Sketchup.

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.

    • Thanks John. You’re invited to host the carnival. I am hosting the first three months just to be comfortable with the basics. But after that, I’ll open for it for hosting.

  2. Interesting page. Thanks! Just one thought, as I understand it 1 is not the ONLY number that is neither prime nor composite. I believe that zero fits that description as well, having an infinite number of factors and all…
