What do you think math is all about? What do your children think? Here is the start of a promising new video series:
Hundred Chart Idea #28: Hang It on the Wall
Math is beautiful when it communicates an abstract idea clearly and provides new insight. Yelena’s hundred chart poster does just that:
[From the Moebius Noodles blog]
Check out my newest home decor item, a hundred chart. The amount of work I put into it, I consider getting it framed to be proudly displayed in the living room. The thing is monumental in several ways:
1. It is monumentally different from my usual approach to choosing math aids. My rule is if it takes me more than 5 minutes to prepare a math manipulative, I skip it and find another way.
2. It is monumentally time-consuming to create from scratch all by yourself.
3. It is monumentally fun to show to a child.

Now she’s provided a fantastic set of free hundred chart printables:
- The Hundred Chart and Game Cards
If you print and cut out the individual cards, you can arrange them so the bigger numbers are higher up, as shown in Yelena’s original blog post.
Thanks, Yelena!
Share Your Ideas
It began with a humble list of seven things in the first (now out of print) edition of my book about teaching home school math. Over the years I added new ideas, and online friends contributed, too, so the list grew to become one of the most popular posts on my blog:
Can you think of anything else we might do with a hundred chart? Add your ideas in the Comments section below, and I’ll add the best ones to our master list.
Math Teachers at Play #59 @ Learners in Bloom
Math Teachers at Play is a monthly Blog Carnival showcasing math activities and puzzles from teachers, parents, and homeschoolers all around the blogosphere.
It is organized by Denise Gaskins at Let’s Play Math, and I’m very excited to be hosting the 59th carnival on Learners in Bloom.
Here’s a little puzzle for you:
59 is the smallest prime that can be expressed using the digits 1 through 9 in order with only the addition and multiplication symbols between them. Can you find a way to express it with these rules? (one solution is at the end of this post).
And now on to the great ideas that were submitted this month…

New Year’s Day
Now is the accepted time to make your regular annual good resolutions. Next week you can begin paving hell with them as usual.
Yesterday, everybody smoked his last cigar, took his last drink, and swore his last oath. Today, we are a pious and exemplary community. Thirty days from now, we shall have cast our reformation to the winds and gone to cutting our ancient shortcomings considerably shorter than ever. We shall also reflect pleasantly upon how we did the same old thing last year about this time.
However, go in, community. New Year’s is a harmless annual institution, of no particular use to anybody save as a scapegoat for promiscuous drunks, and friendly calls, and humbug resolutions, and we wish you to enjoy it with a looseness suited to the greatness of the occasion.
— Mark Twain
Letter to Virginia City Territorial Enterprise, Jan. 1863
For many homeschoolers, January is the time to assess our progress and make a few New Semester’s Resolutions. This year, we resolve to challenge ourselves to more math puzzles. Would you like to join us? Pump up your mental muscles with the 2013 Mathematics Game!

Math Teachers at Play #57 via So I Teach Math and Coach?
From preschool through high school, mathematics offers a wide range of puzzles, games, and interesting ideas to explore. The Math Teachers at Play blog carnival brings you a variety of mathy treats every month. Check it out!
Welcome to the 57th Edition of Math Teachers at Play the Blog Carnival!
The number 57 has often been used in entertainment. As in Agent 57 from the Hit TV Show Danger Mouse, Bruce Springsteen once sang about 57 channels (and nothin’ on), and I can’t forget one of my favorite movies Passenger 57 staring Wesley Snipes.
Quotable: Why Study Algebra?
[Photo by AlphaTangoBravo / Adam Baker via flickr.]
One reason to study algebra: because it’s a building block. And just as it was really hard at first to get those blocks to do what you wanted them to do, so also it can be really hard at first to get algebra to work. But if you persevere, who knows what you might build someday?
Algebra is the beginning of a journey that gives you the skills to solve more complex problems.
…
So, try not to think of Algebra as a boring list of rules and procedures to memorize. Consider algebra as a gateway to exploring the world around us all.— Jason Gibson

Let’s Play Math Book Update
I love math, but had forgotten why I developed a love for math in the first place. This book made me realize how experiences in my childhood lit a spark in me … Denise Gaskins shows us how we can ignite this fire in our own children.
I believe her suggestions are invaluable for homeschoolers, but essential for the many parents whose children are learning to dislike math in school.
If you’ve wavered on whether to pick up my math book, be warned: This is the last month for the introductory sale price. In January, the ebook price will go up to $5.99.
