I initially signed up for Twitter several years ago.
Upon joining, I sent my first Tweet along the lines of:
“I signed up for Twitter… now what do I do?”
And there my account sat, untouched, for several years.
Fast-forward to July 2012… (I downloaded my Twitter archives to see when I actually started using Twitter to connect with other educators.) It is sincerely hard to believe I’ve had Twitter in my professional life for less than a year!
Why?
Because, Twitter has helped me connect with other educators who are just as passionate and crazy as I am about mathematics, education, technology, and most importantly, students! I learn so much that I can hardly remember what I did without Twitter. Connecting with people and content through Twitter is a regular, daily part of my practice. Here are a few highlights of specific ways Twitter has impacted me, and can impact you too:
1) Twitter helps me reflect about teaching and learning.
@mpershan BOOM – so well put.This statement is an epiphany worth sharing with other teachers – read more here: mathmistakes.org/?p=1174

2) Twitter helps facilitate ongoing, relevant professional development.
Educators should not wait for PD.There are so many ways you can learn online & from amazing educators here on Twitter #iaedchat

3) Twitter helps me connect with educators worldwide – check out the Global Math Department! #globalmath

4) Twitter allows me to connect with app developers and make an impact on new tools by providing classroom feedback.
@mathycathy nice! how does it feel to be on the other side? (fyi, we’ll be adding more student features shortly)

RT @edutech20: Ways to use interactive images in the math classroom @thinglink_edu Thanks to @mathycathy for sharing! #edtech #tlchat

5) Twitter allows me to compare teaching strategies with other teachers in no time at all!
Would you believe a teacher in Canada, a teacher in California and I have made videos of how we teach factoring polynomials just to share with one another to compare methods?
@mathycathy @mrvaudrey Yes i demo quad. dist. prop 🙂 convinced my kids r now sold on box over non-recyclable FOIL plus tutors adapting too — Dee (@macMATHster) May 11, 2013
Love modern math methods to teaching algebra @mrvaudrey @mathycathy Looking fwd to some squid =) #edchat #MathIsAwesome — Dee (@macMATHster) May 17, 2013
6) Ever wish another teacher was in your classroom so you could laugh with someone else who “gets it”? Twitter makes that happen too.
@trianglemancsd @absvalteaching I am absolutely dying over here!!!!!Tears!!!!!Tears!!!!!!

7) Twitter helps educators unite and know we’re not alone in our thinking!
@rafranzdavis Amen!I love the way you articulated this point!
— Cathy Yenca (@mathycathy) May 6, 2013
8) Twitter helps me find quality resources I can use in my classroom tomorrow… then provides a platform to discuss how the resources impacted instruction.
Gave @mr_stadel ‘s exponents Day 3 handout to Alg 1 students 2day… what do you think they said about (x – 7)^2 ? mr-stadel.blogspot.com/2013/04/mistak…

Follow me, I’ll follow you, and let’s get learning!
Also check out #mathchat and #ipaded as a few hashtags to get you started on finding other kindred spirits to follow.

I love the #mathchat hashtag! I’ve connected with so many other mathy people from that search alone! 🙂
#mathchat is a good one! Maybe #globalmath and #MTBoS (Math Twitter Blog-o-Sphere) would be others worth exploring.
