The Harmonious Mathematics of Music According to legend, the Ancient Greek Pythagoras was once walking on the streets of Samos, when the sounds of blacksmiths’ hammering suddenly gave him an epiphany. Pythagoras rushed into the shop and, as he analyzed mathematically the shapes of the blacksmiths’ hammers, he laid the foundations of music that today’s Rihanna, Shakira and others are building upon. Wait a minute… Are you talking about the guy from the Pythagorean theorem? I am. And despite what you’ve learned at school, this Pythagorean theorem is absolutely not Pythagoras’ greatest idea — most notably because he probably wasn’t even the one who came up with the Pythagorean theorem. Inspiration “Gary and I use Trello to run our house, taking the best from agile to keep things ticking over smoothly. We have daily stand-ups where we raise tasks, which we then keep track of on Trello. Each task is made into a card, which we can then makes progress notes on, give priority using categories, or assign to either one of us if needed. On Sundays we look back on ‘Completed’ cards, and pat ourselves on the back for a productive week. It’s nice to get things done without nagging, and takes a lot of stress out of doing chores!” Read more

Here's one that may not be so obvious, but is striking when you see it. Recall the Fibonacci numbers: n: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14,... fn: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377,... Now let's look at some of their greatest common divisors (gcd's): Google Keep: Lit Circles - Teacher Tech Guest Blog post by Rayna Freedman (@rlfreedm) Digital PostIts I fell in love with Google Keep at first sight. Once I saw the color-coded notes, reminders, labels (think hashtags), and image upload capability my head began swirling with possibilities for my 5th-grade students. What a great tool to help students organize their assignments or projects! Aha!

A Random Math Fun Fact! From the Fun Fact files, here is a Random Fun Fact, at the Advanced level: The traditional proof that the square root of 2 is irrational (attributed to Pythagoras) depends on understanding facts about the divisibility of the integers. (It is often covered in calculus courses and begins by assuming Sqrt[2]=x/y where x/y is in smallest terms, then concludes that both x and y are even, a contradiction. See the Hardy and Wright reference.) But the proof we're about to see (from the Landau reference) requires only an understanding of the ordering of the real numbers!

21 Digital Tools To Build Vocabulary - 21 Digital Tools To Build Vocabulary by Kimberly Tyson, Ph.D If you follow this blog, you know that I believe effective vocabulary instruction is just about the most important instructional activity for teachers to get right. For lots of reasons. Vocabulary influences fluency, comprehension, and student achievement. Sums of Two Squares Ways In the Fun Fact Sums of Two Squares, we've seen which numbers can be written as the sum of two squares. For instance, 11 cannot, but 13 can (as 32+22). A related question, with a surprising answer, is: on average, how many ways can a number can be written as the sum of two squares? We should clarify what we mean by average. Let W(N) is the number of ways to write N as the sum of two squares. Thus W(11)=0, and W(13)=8 (as sums of squares of all possible combinations of +/-3 and +/-2 , in either order).
