Welcome to the 10th Edition of the Mathematics and Multimedia blog carnival. I hope you have enjoyed the 9th edition posted Virtual Math Tutor. We have very interesting submissions in this edition but before we begin, let’s have some trivia about the number 10 from Wikipedia:

- Ten is the sum of the first 3 prime numbers.
- A polygon with 10 sides is called a decagon.
- Ten is the atomic number of neon.
- There are 10 commandments in the Bible.
- Ten is the number of violin sonatas composed by Beethoven.
*The number of monsters of Ben 10?*

**Math Connections**

**John Cook** connects English words to prime numbers in his article Words that are primes base 36 posted at The Endeavour. Numbers in base 36 are written using 0, 1, 2, …, 9, A, B, C, …, Z as “digits.”

**Romeo Vitelli** shocked me in the first of his 3-part series on the trials and tribulations of Alan Turing in The Turing Problem posted at Providentia. This is the first time I read about the real life story of Turing. To those who do not know, Alan Turing was the pioneer of artificial intelligence.

**Mathematics Teaching**

**Earl Samuelson** introduces integral calculus from a backward design approach at Introduction to Integral Calculus posted at Samuelson Mathxp.

**Erlina Ronda, **a fellow Filipino has another unique post** **on Introducing the negative number via the numberline with a twist posted at Mathematics for Teaching.

**John Golden r**eflects about both sides (the rewards and challenges) of mathematics teaching in his Screwtape for Teachers posted at Math Hombre.

I came across with **Robert Talbert’s** presentation on Spearking of the Inverted Classroom at Casting Out Nines and I think it is very useful for teachers and educators.

**Technology Integration**

For Iphone lovers,** Mathew Needleman** presents How to Create Your First iPhone App posted at Creating Lifelong Learners.

**Kristi Grande** encourages us to talk about what we have learned in Love of Learning Blog: Podcasting to Increase Student Achievement in Math posted at Love of Learning Blog.

**Gianluigi Filippelli **has written a guide on installing a math script in order to use Latex in science blogs in MathJax: script for Latex posted at Doc Madhattan.

**Guillermo Bautista **(that’s me), presents construction of a square paper-folding simulation in Paper Folding and Proof at GeoGebra Applet Central.

Saturday Morning Breakfast Cereal has an excellent presentation on strategies of hand multiplication called Polish Hand Magic. We have a slightly different versionhere in the Philippines, but I have no time to work on the proof yet. I’ll post it within the month.

For those who are looking for math blogs and creating blogrolls, you may want to check out** Rashmi Kathuria**‘s math blogs at Mathematics Bloggers.

**Announcments**

- To all GeoGebra users and Blogspot bloggers , I would like to invite you to work with me at GeoGebra Applet Central. It is a blog where I place my GeoGebra applets. I am opening it for contributors. Contact me if you are interested.
**Carnival Hosts Needed:**Want to promote your blog? Host the Math and Multimedia Carnival. May, June, and July are vacant.

That concludes this edition. Submit your blog article to the next edition of **Mathematics and Multimedia **blog carnival using our carnival submission form. The next carnival will be at Love of Learning Blog. Past posts and future hosts can be found on our blog carnival index page.

Dear Guillermo Bautista, Mathematician Magician:

My name is Allen Berg and I am a retired classroom teacher but still very much an active learner and teacher (many subjects: STEM + Arts (STEAM 🙂 and writing and sociology etc. I receive your daily newsletter with continuing joy, you have helped me learn a lot about the new technologies of the internet, like geogebra and open courseware java interactive tools, etc.

I have taught every level from K – University (about 30 years 🙂 and I am active at http://www.edutopia.org, and last Christmas I taught myself how to create a wikispace for a High School Geometry Class (work-in-progress)…

Today, your Celebration of the Number 10 reminded me of my arts coloring fun way to teach the multiplication Times Tables; I have posted a brief series of photograph examples at my picasa web album:

https://picasaweb.google.com/kasha8888/TimesTablesColoring#

So now I am wondering if you can figure out a computer software method to enable students to do the coloring with their computer, to reveal the colored-boxes patterns, which could be helpful for learning the fun and power of numbers…

I am a very techno-newbie; I cannot even create a 10 x 10 1-100 number grid using MS Word, I hand-draw with a ruler the old-fashioned way… 🙂

I would be happy to hear from you about any ideas or comments for this project…

Sincerely,

Allen Berg

Allen,

Thank you very much for the compliment Allen. I am only an amateur in everything so I am a little embarrassed by the compliment (Thank you still). Anyway,I am not very familiar with coloring software, but I think while looking, the best software to do this is a spreadsheet. Try using Microsoft Excel, the spreadsheet in Open Office, or even the Google Docs spreadsheet. You can perform automatic computations as well as you can easily color the cells.

If you have created a Wikispace, surely you can explore it. Please contact me via email (mathandmultimedia@gmail.com) if you need help.

Guillermo
