Math Teachers at Play #47 via Math Hombre

Welcome to the 47th edition of the Math Teachers at Play Blog Carnival!
http://bit.ly/MTAP47

The Number Dictionary reveals two particularly interesting facts about 47.

  • 47 is a prime and a Gaussian prime.
  • 47 is the difference between two squares.


I don’t think I’ve appreciated 47 nearly enough before this carnival. But we should move on since there are a lot of neat entries this month…

Math Teachers at Play #46: Living Books for Math

Welcome to the Math Teachers At Play blog carnival — which is not just for math teachers! Here is a smorgasbord of ideas for learning, teaching, and playing around with math from preschool to pre-college. Some articles were submitted by their authors, others were drawn from the immense backlog in my blog reader. If you like to learn new things, you are sure to find something of interest.

Living Books for Math

A child’s intercourse must always be with good books, the best that we can find… We must put into their hands the sources which we must needs use for ourselves, the best books of the best writers.

For the mind is capable of dealing with only one kind of food; it lives, grows and is nourished upon ideas only; mere information is to it as a meal of sawdust to the body.

Charlotte Mason
Toward A Philosophy of Education

Princess Kitten and I took a longer than usual holiday break from homeschooling, but now I’m in plan-for-the-new-semester mode. I hope to include more living math in our schedule, so I decided to illustrate this edition of the MTaP carnival with a few of my favorite living math books. I’d love to hear more living book suggestions in the comments!

If you click on a book cover, the links take you to Amazon.com, where you can read reviews and other details (and where I earn a small affiliate commission if you actually buy the book), but all of these books should be available through your public library or via inter-library loan.

Let the mathematical fun begin…

The new Math Teachers at Play blog carnival is up for your browsing pleasure:

If you think the carnival seems shorter than usual, you’re right. We had many more submissions, but it appears that the blog carnival website is having trouble again. If your article is missing (as mine is), I’m sorry! Please try again next month.

This is the first time I ever hosted a blog carnival so please bear with me.

While reading the posts submitted to this month’s Math Teachers at Play blog carnival, I was struck by how visualization is very important in teaching math, and just math in general. I was happy to read all the “visualization” posts since my recent interest is exactly in visual representations and how they help in learning, especially learning math.

For instance…

Math Teachers at Play #41 via I Hope This Old Train Breaks Down…

The new Math Teachers at Play blog carnival has plenty of fun for math fans of all ages:

Willkommen! Welcome to the Math Teachers at Play blog carnival! Whether you are a teacher, homeschooler, parent, or a math enthusiast interested in general discussions about mathematics, there is a little bit of something for everyone here. Some of these links came as direct submissions by bloggers, and the others came from my Google Reader.

To start, here are some fun facts about the number 41:

  • Starting with 41, if you add 2, then 4, then 6, then 8, etc… you would get a string of 40 prime numbers in a row!
  • 41 is also a Centered Square Number, which means that it is the sum of two consecutive squares — 4^2 and 5^2, in this case. Can you figure out how this picture relates to the Center Square Numbers, and use the picture to explain why all Center Square Numbers are 1 (mod 4)?

Welcome to the Math Teachers At Play blog carnival — it’s not just for math teachers!

If you like to learn new things and play around with ideas, you’re sure to find something intriguing here. Don’t try to read all 40(!) posts at once; take the time to enjoy browsing. Savor a few posts today, and then come back for another helping tomorrow or next week.

At my fortieth birthday party, I got a few of those gag presents meant to remind me how terribly old I was getting. Math Teachers at Play is less than 40 months old (it used to come out twice a month), but just imagine how many great math posts have been included over the months, in all 40 issues.
