    Books

    There are so many! Click here to see a list of all the math picture books I’ve reviewed so far. Here are my two favorite ones:

    One Grain of Rice

    Exotic, beautiful, and instructive, this “mathematical folktale” by author-illustrator Demi emerged from her love of India. This retelling of the classing “doubling” story is about Rani, a clever girl who outsmarts a very selfish raja and saves her village. When offered a reward for a good deed, she asks only for one grain of rice, doubled each day for 30 days.

  • The Declaration of Independence is Math!

    The Declaration of Independence is Math!

    Dates are math!

    Today is the official day that Americans celebrate declaring independence.

    But did you know that the The Declaration of Independence was actually accepted on July 2, 1776.

    John Adams wrote: “The second day of July 1776 will be the most memorable epocha in the history of America.”

    Add two to that, Mr. Adams.

    What happened?

    When The Declaration of Independence was written out, it was dated July 4.

    And the physical pen-to-paper signing of the Declaration of Independence didn’t start until August 2.

    Even crazier, the last signature on the The Declaration of Independence wasn’t penned until after January 1777!

    Where’s the math?

    Check out the various questions you can ask about these dates:

    • What’s the difference in days between the acceptance of The Declaration of Independence and the date of the document?
    • What’s the difference in days between the acceptance and the first signature?
    • How about between the date of The Declaration of Independence and the last signature? (that’s an inequality!)

    Happy Independence Day, y’all!

  • Why I Believe in Santa Claus

    Why I Believe in Santa Claus

    This post originally appeared on The HSBA Post on December 25, 2011.

    I’m not sure how I discovered that my parents acted as Santa Claus. But I distinctly remember the sinking feeling. I also remember quickly making the connection for the Easter Bunny and the Tooth Fairy. Within five minutes all mysticism in my life had vanished.

    Ten years later, it all came back.

    It was the middle of the 80s. My parents were recently divorced. My dad was in oil and gas and had been laid off. We had no money. Mom said we were broke — not poor. But it sure felt like we were poor.

    We had Christmas lights and ornaments from all the past years. We lived in the country so we got a tree from the “backyard.” It required a couple of long needle East Texas pines wired together, but it worked.

    And we were told not to expect to find much underneath it on Christmas Day.

    Strange Phone Calls

    I remember overhearing a conversation my mom was having on the phone in mid-December.

    “We have water and electricity and food. It’s not much, but we’ll be okay. <pause> Really? But I’m sure there are many other families in more need than we are. <pause> I see. Well if that’s the case, yes. We would appreciate it very much. Thank you.”

    My best friend called with an interesting question. “We’ve exchanged names for family Christmas, and I’ve drawn the name of a cousin that’s about your little brother’s age. I don’t have any idea what to get for him. Can you ask him what he likes, and maybe that will help me?”

    Looking back, there were many other strange and unusual phone calls the two weeks leading up to Christmas.

    A Christmas Eve Like No Other

    On Christmas Eve we had a constant flow of visitors. A local car dealership showed up offering a bag filled with wrapped presents. Some people from my best friend’s church came by with three bags of gifts. Another church sent a handful of representatives with a huge basket of turkey and dressing and all the fixings. Friends and churches from all over the neighborhood, and even people we’d never met, were showing up to share with us.

    2011 Christmas Tree
    Stlll in the same house, this is what the 2011 Christmas tree looks like. (We can afford to buy one now, but we still like a non-standard shape.)

    It was so amazing to see such love and caring — and for it to come our way. I was too young to really understand the generosity, but I knew it was special. Very special.

    We went to midnight mass, as we always did, and mom was crying just a little more than normal.

    A Magical Christmas Morning

    Christmas day was insane. Santa Claus had really come.

    I remember opening presents and seeing mom’s face. In years past her look was of excitement to see if we liked what she had given. This year, she had a different look. She was truly curious. And she was excited and amazed that her young children wouldn’t have to know the heartache of an empty Christmas morning.

    I’m quite sure it didn’t occur to her, though, that the gifts the community had shared included one more: believing that people really can love one-another. The very heart of Christianity.

    The Gifts of God

    Jesus gave us a gift with His death. We get to live in Him forever. But with His birth, He also gave us a special gift, one that we get right now. He gave us generosity and love to share with each other. And at Christmas, that comes out in the shape of a fat, old, hairy, jolly character we call Santa Claus. A man who’s famous for his generosity.

    I hope that no one ever has to be poor or even broke. While it wasn’t easy going through that part of my childhood, I am thankful for the lessons we learned. I am grateful that I was able to see first hand the generosity and love of my fellow man that Christmas.

    Merry Christmas… and may we all be filled with the Christmas spirit!

  • Wrapping Paper – Doing the Math this Season

    Wrapping Paper – Doing the Math this Season

    As you wrap presents this holiday season, take a minute to notice the patterns in the wrapping paper. You might just find some math!

    Christmas Paper

    How does the paper come together in the back? Does it neatly match up, seamlessly? Or is it way off?

    Are you able to scootch things a little so that you can get the paper to line up?

    What happens when you use a different box?

    Is this really math?

    Absolutely!

    Consider wallpaper: it has a pattern that repeats every so many inches. When you put wallpaper in your home it’s important to know how often it repeats so that you can match patterns in the corners and around windows, etc.

    Patterned wrapping paper also repeats. Most people ignore it because they don’t think about matching the patterns in the back when wrapping gifts.

    Unless they are particularly detail oriented, a perfectionist, or want to teach a little bit of math at home while wrapping presents…

    Choose your wrapping paper to match your boxes!

    On this box your wrapping paper would go around 8 1/2 + 4 + 8 1/2 + 4 inches.

    This means the wrapping paper would travel 25 inches before meeting back up with itself. So any wrapping paper that repeats after 5 inches or 25 inches will match back up in the back. Both 5 and 25 are factors of 25 – and that’s math!

    If you wrap the box the other way, instead, like this,

    …the wrapping paper would travel 26 inches. Therefore any patterned wrapping paper that repeated after 2 inches, 13 inches or 26 inches would match in the back perfectly.

    A box whose “wrap around” distance was 30 inches could use any wrapping paper that repeated after 2 inches, 3 inches, 5 inches, 6 inches, 10 inches, 15 inches or 30 inches. All those are factors of 30.

    Choose your boxes to match your wrapping paper!

    Or do it the other way – figure out how frequently your pattern repeats. Any box that has a girth of a multiple of this number can be wrapped perfectly. (Girth is the distance around the box – where you wrap the paper.)

    For instance, if your wrapping paper repeated after 2 1/2 inches, you would look for boxes that have a girth of 2 1/2 inches (a tiny ring box), 5 inches, 7 1/2 inches, 10 inches. All the way up to giant boxes that have a girth of 314 1/2 inches.

    Your turn!

    How often does your favorite wrapping paper repeat? Have you found the perfect box/wrapping paper combination? Share your wrapping paper math discoveries in the comments!
