**Welcome to the Math and Multimedia Blog Carnival #14.**

As is the usual tradition we’ll start with some properties of 14, **first words to WolframAlpha** which provides properties for any number entered including the prime factorisation and various properties. If we choose to investigate **fourteen as word** instead we could look for example at the frequency of use over time as well as definitions of the word.

We could even find out the Scrabble score for fourteen!

A great site for investigating number properties is Tanya Khovanova’s **Number Gossip site**, here we learn that 14 is a Catalan number, composite, deficient, even, odious and square free. The site gives clear definitions of all the terms used.

### Teaching

Having discussed number properties it seems appropriate to move to the first carnival submission where Jonathan Walsh presents **Improve your Mental Maths** posted at **Smart Blog.**

Erlina Ronda presents **Introducing triangle congruence** at **Mathematics for Teaching**.

William Emeny illustrates an excellent resource for illustrating the Monty Hall problem in **Stay or Switch? The Monty Hall Problem** at **Great Maths Teaching Ideas.**

Shari has written a thoughtful post **Is Math Black and White? **at **Math + Technology = Fun**.

Thinking about older students including those going into higher education Colleen Young (that’s me!) wrote this post ‘**For Students**‘.

### Problem Solving and Proofs

Guillermo P. Bautista Jr. presents **Paper Folding: Locating the square root of a number on the number line** posted at **Mathematics and Multimedia**.

### Real Life Mathematics

Pat Oaklief presents **How You Can Support Your Daughter in Math and Science** posted at her **Amigram Blog**.

David Wetzel discusses **making real world connections in the teaching of algebra **at **Teaching Science and Math **and David Wees has fitted a parabola to the curve of a leaning plant in **Leaning Plants** at **21st Century Educator**.

**Technology**

John Golden has been trying out **Doink** and presents **Linear Animation** posted at **Mathhombre**.

You will see I have mentioned **Evernote** in the above blog post ‘**For Students**‘ – it seems appropriate to illustrate an Evernote shared notebook with **this one** I created for Carnival resources.

This is a carnival so we should really end with some music – **mathematical songs** of course!

That concludes this edition. Thank you for reading. Submit your blog article to the next edition of** Mathematics and Multimedia Blog Carnival** using our **carnival submission form**. Past posts and future hosts can be found on our **blog carnival index page**.

Just wanted to say thanks for the inclusion of my blog in your carnival.

I think you’ve got an impressive website and I hope to see more posts of yours.

If you ever want to contact me, just head over to my blog (Smart Blog) and go to my ‘contact’ page.

I’m going to include a link to your website from my maths post, so that people can have a look at this great mathematical website.

I wish you all the best for the future,

Jonny.

I liked your post Jonny and was pleased to include it, I also liked your blog; there are many posts there aligned with my own interests.

I like the idea of these carnivals providing a good variety and perhaps introducing readers to blogs they may not have come across before.

Thank you Coleen for including my post in this great collection. I enjoyed your introduction especially the WolframAlpha activity.

I agree with you Erlina – a problem solving approach is a good way to approach congruence, I have used a similar approach myself.

As for Wolfram Alpha – I’m a fan! It’s rather clever!
