It was the summer of 2012 when I talked my colleagues, Erin and Melissa, into signing up for a week-long training in Palo Alto, California, to start a new Math Teachers’ Circle (MTC) program in our area.

It was there that I first learned about Exploding Dots from Diana White, an associate professor from the University of Colorado Denver. Diana said that Exploding Dots was developed by James Tanton — and I recognized his name instantly because I have his book *Solve It* and have seen many of his great videos online.

Exploding Dots is way fun! It was like playing a game [with an exploding dot machine] that became more and more challenging, and this machine invited us to make connections and explore different algorithms. And when we got to explore a fractional base, my mind was blown. Of course, we wanted to share Exploding Dots immediately at our first MTC, so here’s Nate Carlson, one of the leaders at our site, facilitating the session back in September 2012.

**If you’re not familiar with Exploding Dots, you want to get in on this!**

Exploding Dots is an astounding mathematical story that starts at the very beginning of mathematics – it assumes nothing – and swiftly takes you on a wondrous journey through grade school arithmetic, polynomial algebra, and infinite sums to unsolved problems baffling mathematicians to this day.

And this brings me to the Global Math Project (GMP)! Founded by James Tanton, Raj Shah, Brianna Donaldson, and others, the GMP is launching its first **Global Math Week, starting this October 10, 2017**. Its goal is to do what the Hour of Code did for coding, but for mathematics. The goal is to reach 1,000,000 students across the globe to do Exploding Dots! (Over half a million students in over 100 countries have already registered!)

Please register and join me and my 130 students in grades 7 and 8 to experience this wonderful and joyous content of Exploding Dots!

Oh wow! I have James Tanton’s book Solve It also and have been watching his Visual Math course for The Teaching Company. Very much looking forward to checking this out!

The other day, while I was at work, my sister stole

my apple ipad and tested to see if it can survive a 30 foot drop,

just so she can be a youtube sensation. My iPad is

now destroyed and she has 83 views. I know this is entirely off

topic but I had to share it with someone!

I was curious if you ever considered changing the page layout of

your site? Its very well written; I love what

youve got to say. But maybe you could a little more in the way of content so people could connect with it

better. Youve got an awful lot of text for only having one or 2 pictures.

Maybe you could space it out better?

Hi everyone, it’s my first go to see at this website, and

paragraph is actually fruitful designed for me, keep up posting these types of content.

Very good info. Lucky me I recently found your blog by chance

(stumbleupon). I’ve saved as a favorite for later!

Erectile dysfunction or have an impact involved in (ED) is the unsuitableness to upon out and subsistence growing an erection luomort.kraftfuld.com/instruktioner/jenny-thai-massage.php in the amenities of all correct diplomate coitus or activity. Erectile dysfunction or erectile meeting are the preferred terms as opposed to impotence. There are no regimented criteria defining how unchanging the uncontrollable has to be and since what duration it requisite be propinquitous to considered ED. The Diagnostic and Statistical Conductor of Screwy Disorder-5 specifies a duration of at least 6 months in its account of ED.

Bodies model in in all peerless shapes and sizes – that’s partly what makes each of us disconnected and assorted from each other. It’s extraordinary diewa.stemningen.com/bare-at-gore/atleter.php to sagacity that the greatness of a prepubescence’s penis is clear via genetic traits that he inherits from his parents – reputable like we come around our altitude, liking color, and flay tone. The studies that sooner a be wearing been conducted classify the middling grown-up penis largeness between 5 and 6 inches when fully rally, as studied from the lowest parcel out of the hire, valid upon the point of departure of the penis, to the gratuity of the penis.
