Review and a Give-away

So if you've been reading for the past couple of weeks, you know that we've been playing with mathematics.
And yes, I do mean playing.  :)

Have you gathered that I love this book?
We're not finished with it, of course, and probably won't be for years, and obviously I won't make any of us wait that long before telling you about it and having a give-away!

So.  On to it.
Amazing Math Projects You Can Build Yourself.

From the editor:
"From prime numbers to paraboloids, Amazing Math Projects You Can Build Yourself introduces readers ages 9 and up to the beauty and wonder of math through hands-on activities. Kids will cut apart shapes to discover area formulas, build beautiful geometric models to explore their properties, and amaze friends with the mysterious Möbius strip.
Amazing Math Projects You Can Build Yourself includes projects about number patterns, lines, curves, and shapes. Each activity includes intriguing facts, vocabulary builders, and connections to other topics. A companion website, includes video instructions for many projects in the book and provides additional activities.
Who would have thought that math could be so much fun?"

Trev and I -and Maddie, sometimes- have explored every bit of the first twenty-two pages.  That might not seem like a lot to you, but, we've:
  • learned how to count in different numeral systems (including binary and base-5)
  • learned that we we're somewhat familiar with this already, as we keep time with a base-60 system
  • practiced using a base-5 system using coins
  • made conversions of base-10 into base-5, and vice versa
  • made a soroban abacus and learned how to use it
  • learned what triangle, square, and rectangle numbers are
  • learned how to sum a series of numbers in a triangle
  • learned the puzzle of changing direction of a triangle by moving three coins (I knew this one, so was able to help them)
  • learned the sum of any two consecutive triangle numbers add up to a square number
  • learned about square roots, and cubes
  • found patterns in square numbers (start with "one" coin... it 's a perfect square.  Add "three", it's the next perfect square.  Add "five", it's the next, then "seven" for the next... "nine" for the next... aaaah.
  • learned what 'composite' means
  • learned what "prime" means
  • learned how to find prime numbers using Eratosthenes method from about 200bce
Next is a project for multiplying fractions... I can't wait!  :)  Really.

Coming up are making a fraction addition dial, learning the Fibonacci Sequence, making a square magically appear using Fibonacci numbers, finding spirals in a sunflower, Golden Ratio, finding the Golden Ratio around you, drawing a golden spiral, and three more large sections consisting of Angles, Curves and Paths, Shapes, and Patterns... (up until the mention of Angles, Curves and Paths, all of these things have been and are in the first section, Numbers and Counting).

This is a fantastic book.  I wish I had a box full of them to just pass out to friends.  And strangers.  :)

I mean, we all have different styles and perceptions, and I am definitely not a mathematician, so you have to take that into account, I guess.  But I love, love, love this book.

It's interesting and challenging... easy to understand, and fascinating.
We've investigated the binary numeral system (on our own), gotten out our one-inch cubes, dumped out coins, played with the calculator, and had our cuisenaire rods all over tables while we've read and investigated.
Our experience has been rich and full with this book.

So.  Thumbs Up, in case I haven't made that clear.  ; )

Now... on to the give-away.
First know that I love this book well enough that I shall purchase one (or possibly two) myself to give away here, but this particular give-away is sponsored by Nomad Press, and they have something different (but very cool) for you.  It's their Discover Series... a set of four books!

The winner will receive one of each of the following books:

We'll do this the usual way...
  • first entry for leaving a comment
  • an extra entry if you are or become a follower (in hopes that we'll have lots more cool give-away opportunities)
  • third entry for a facebook mention or tweet.
You don't need to leave more than one comment, I do the drawing by hand, so you can just give the the particulars in your comment.

We'll have the drawing open until next Thursday afternoon, November 17th.  Open to U.S. shipping addresses.

Should you want to try out Amazing Math Projects for yourself (and don't want to wait on me), it's $12.76 today on Amazon!  :)

And coming right after that, we'll have a give-away for something beautiful from Heart Rockin Jewelry!  You won't want to miss that!

    I follow.

  6. I'm already a follower, which is why I'd already been coveting the math book. Looks great! I'm sure the other four will equally enjoyable in their own ways, so I'll share the link on fb as well. Thanks!

  7. after reading your blog post about "amazing math" we got the book from our library and you're absolutely right: it is fantastic!!
    we also checked out a book about inventions by leonardo davinci, which is equally great.

    And we have DaVinci, also! :)

  9. This is an amazing giveaway! Those books look really interesting. I love your site, love the freedom and natural learning. Our two little ones are at home (5 and 3) and I absolutely love the seeing them explore and learn just by being kids. Thanks for the chance to win!
