## Mathematics and Multimedia Blog Carnival #16

[24 Oct 2011]

This is the "coming of age" edition of the Mathematics and Multimedia Blog Carnival. Here are some (customary & mandatory) factoids about the number 16:

• In many countries, 16 is the age of consent, and the age where young people can get a license to legally control a 1-tonne projectile. Also, sixteen happens to be the age of many of our students.
• In Chinese and Japanese, where numbers are written more logically than in European languages, "16" is made up of "10" plus "6", as follows:

Chinese characters for "16"

• Sixteen is the sum of the first 4 odd numbers.
• Sixteen is the base for the hexadecimal number system, used extensively in computing. Here is the number 16 written using hexadecimal numbers: 1016.

On with the show.

(I’m using the topic headings as decreed in the Mathematics and Multimedia Blog Carnival manifesto.)

### Mathematics teaching

(1) Bon Crowder of Math is not a Four Letter Word has written an interesting thought piece on the difference between motivating and inspiring students, in:

(2) Denise in Let’s Play Math! says “Let’s look at two common mental models — partitive division and measurement division — to see how the sister could have divided her pie…” in:

(3) Colleen Young (who has a “keen interest in how new technologies can deepen the learning experience for students”) has begun a new blog aimed at students. She’s right – most math blogs preach to the choir – it’s about time there were more blogs addressed to students.

Hello Students!

(4) And finally in this section, here are my suggestions (right here in squareCircleZ) on:

### Technology integration

John Golden, of MathHombre, was inspired by a Dor Abrahamson video to create a GeoGebra app which helps students understand fractions. Here it is:

### Mathematics

(1) Natasha wrote an article in eIMACS about a professional mathematician in:

(IMACS is the Institute for Mathematics and Computer Science, an independent teaching and educational research institute.)

(2) Earl Samuelson (of samuelson mathxp’s posterous) submitted 3 articles for this Carnival. In the first, he outlines graphical, algebraic and logarithmic approaches to solving exponential functions

Solving Exponential Equations: “Various Perspectives"

(3) In the second article, entitled “Carpe Diem” (seize the day), Earl writes an interesting exposition involving the math of time measurement:

(4) Guillermo P. Bautista Jr. (the father of this blog carnival) in Mathematics and Multimedia presents:

Subset: a set contained in a set

### Math connections

Erlina Ronda at Mathematics for Teaching explains how to find the number of shortest paths on a chess board, in:

### Real life math

(1) John Cook of The Endeavour gives us a curve with an interesting property, in:

(2) Earl Samuelson was moved by the same Dor Abrahamson video that inspired John Golden. Here is Earl’s third submission for this carnival:

(3) Katie Sorene of TripBase gives us the second list in a series of mathematically interesting buildings, in:

Most Mathematically Interesting Buildings in the World (7 More)

### The next Mathematics and Multimedia Blog Carnival

Carnival #17 will be hosted by Mathematics for Teaching on 28 Nov 2011, with submissions due by Fri 11 Nov 2011. Submissions can be made via this link.

### 12 Comments on “Mathematics and Multimedia Blog Carnival #16”

1. Rene says:

It is one of the major achievements of “Western” mathematics that 16 is NOT written as 10 and 6. Otherwise, I appreciate the many efforts to teach math more emotionally.

2. Colleen Young says:

Thanks for including my ‘Hello Students!’

What a wonderful variety of submissions here.

3. Guillermo Batuista says:

Thanks you very much for hosting. I am going to make an announcement tomorrow.

4. Terry Kaufman says:

Thank you for including our post.

6. Philip Petrov says:

@Rene – It’s not at all “achievements of “Western” mathematics” – it’s “achievement of the “Eastern” mathematics”. The numbers which you are using today are not called “Arabic numerals” just like that. They are arabic!

8. narayanan says:

@Rene Philip Petrov : It’s not even “Arabic”. It is Indian system. It was called Indo Arabic since west got it through them.

9. Erlina Ronda says:

hi, thanks for including my post. great collection you got here.
