## The Masterplan blog mini review

Dan Stucke is an inner-city Math teacher in the UK. His blog, The Masterplan, is not exclusively about Math but he does post a fair amount about the subject, especially things related to Web2.0.

I discovered some nice gems from The Masterplan:

- Maths in the Movies
- Voicethread and Math
- 5 card Flickr storytelling game
- Head-to-head Math competition for kids

If you have an interest in Web 2.0, and teaching kids Math, or if you're in the UK, you should check out this blog.

*[If you have a Math-related web-site, or if you blog a lot about Math, and if you’re site isn’t mainly commercial, let’s exchange mini reviews like this one. You review my site, or mention it in one of your posts, and I’ll do the same for you. And, let’s also exchange blogroll links. See this post if you’re interested in a review swap.]*

## Mr. Higgins’ Blog mini review

Chris Higgins plays in the fields of Math, Computer Science, and Web 2.0 as do I. So, I already like the man. Chris is a Math and Comp Sci teacher, and owner of Mr. Higgins' Blog.

The first thing I notice about Mr. Higgins blog is the very engaging use of images and videos. Text by itself can be so unappealing. (Yes, I'm learning!) And, I've fallen in love with the banner on his site.

## A VERY cool after-Christmas toy

Just yesterday I joined MindWare's mailing list and I got an ad from them a little while ago. They've got a clearance sale going on for a Skyrail Suspension Marble Run, touted as "The World's Largest Marble Run!" for $29.95 plus shipping. I ordered two, one for my nieces and the other for me!

## If you have a Math-related web-site or blog …

I'd like to spread some holiday cheer. If you have a web-site that is predominantly Math-related and mostly non-commercial - a few ads are ok if you have lots of good content and aren't mainly a money-making site - then let's consider an article or blogroll swap.

Here's what I have in mind:

- You leave me a comment on this blog post with your blog or web-site address. You also leave your email address but only I will see it.
- I look at your site. If it meets my two criteria - mostly Math-related and mostly non-commercial - then I'll write to you.
- You write a one or two paragraph review of my site as a blog article (or a few sentences on your web-site if your site is not a blog.)
- I, in turn, write a short review of your site. I will clearly identify in my little article that I'm doing this as an exchange so that my article is not construed as an endorsement of your site. I invite you to do the same.
- I link to your site and you link to mine.
- We each pick the anchor text we would like the other to use in linking to one another's site. Don't worry if you don't know what that means.
- If you would like to do a blogroll exchange and not an article exchange, I'm fine with that. We could certainly also do both.

Why am I offering exchanges? I'm interested in getting more links, more readers and more traffic to my site and I'd like to educate readers about other Math sites.

Consider that Wild About Math! has a Google PageRank of 5, which is pretty decent and that this blog has over 600 RSS readers. An article and a link would serve us both well.

## MMM #22: The Grinch Bug at Blinkdagger

Blinkdagger has posted the latest Monday Math Madness problem!

Here's the problem. Check out the rules and submission info at Bllinkdagger.

I got extremely sick and was wondering if I got a weird virus. I heard there was this Grinch Bug going around. Making you sick throughout Christmas Holiday. I decided to go check it out. The doctor told me their test measurements are 99 percent accurate (regardless if results are positive or negative). This Grinch Bug only occur randomly in the population (assume infected people are independent and distributed evenly), around 1 in every 10,000 people. He told me not to worry.

Today I got the report. It came out positive! What are the chances I actually have the disease? Should I be worried?

Happy Holidays to everyone!

## MMM #21: We have a winner!

MMM #21 was easier than I thought as most of the submitters got the right answer. Random.org picked Khey Jenq Lim as winner. Congratulations, Khey! I'll be contacting you to get you your prize.

## MMM #21: How many divisors?

Blinkdagger has announced the winner for MMM #20. Congratulations, Diego Vila Cid!

Now, onto MMM #21.

I have a Rubik’s Revolution, courtesy of Techno Source (or $10 Amazon.com gift certificate, if you prefer, or $10 in USD via PayPal to non-US folks) to give to the winner.

## Now that the MMM #20 submission deadline is past …

In the next few days, Quan and Daniel will be picking a random winner for MMM #20 over at Blinkdagger. We received 20 solutions. What's very interesting to me is that, of those 20, two people were able to solve the problem without using trigonometry. Here's a hint, can you tell if the center piece of the pie is bigger than either of the edge pieces without computing the exact area of any of the pieces? It's too late to submit an entry if you haven't already, so my question is just for fun. Leave a comment on this post if you see an easy way to solve the problem.
