Thanks to everyone that stopped by to help us celebrate our 20th birthday. We enjoyed sharing it with all of you. Follow us on Twitter and Facebook for the most up to date photos and happenings here at Forum.

The Math Forum was founded (as the Geometry Forum) on June 15, 1992 at Swarthmore College by Professor Gene Klotz. Since the Web didn’t exist yet, one of the projects we undertook was to develop a news reader, called the Forum News Gateway, that would allow easy sharing of mathematical graphics and notation. The introduction of Mosaic, the first popular “web” browser, in 1993 made our fancy news reader unnecessary, and we instead focused our energies on helping educators understand why they might care about “the Internet”.

In 1993, our first mentored Geometry Problem of the Week debuted, thanks to a suggestion by high school geometry teacher Keith Grove. When asked, after a week-long summer institute with Geometry Forum, what would keep him coming back to our site, he said, “If there were a geometry problem posted every week, I’d have my kids do it.” So we did, and he did – as did dozens more students … then hundreds … then thousands! Annie mentored them all (by e-mail!), and mapped their locations on a world map wall mural in our first office, but soon enough we ran out of countries to chart. Over the next six years we added seven new Problems of the Week services and developed our first PoW “office,” through which we ultimately mentored hundreds of thousands of students. We also launched our Internet Math Library, and our hugely popular ask-an-expert service, Ask Dr. Math. By 1996 we officially became the Math Forum, thanks in part to a second grant from the National Science Foundation (NSF).

*Were you mentored on a PoW? Did you use them in your classes? Have you ever asked a question of Dr. Math or browsed the Internet Math Library? We’d love to hear what you remember from our 20 years of being on the Internet! You can leave us a comment below or Tweet to @themathforum.*

Check out our full timeline here: http://mathforum.org/timeline.html

Today, the Math Forum as you know it operates under Drexel University’s Goodwin College of Professional Studies in Philadelphia. We have millions of pages of content and thousands of registered Problem of the Week members from all over the world.

*How do you use the Math Forum now? What new features, such as the new look for the PoWs, the Problem Solving Activity Series, the Primary PoWs, or the blogs and videos, do you like? We’d love to hear your reflections about how the Forum has grown!*

We hope you’ll stay tuned as we embark on the next 20 years, and we’d love to hear your happy birthday wishes or your favorite Math Forum memory in the comments below.

Happy Solar / Calendar Birthday….And may you have many more! Zim Olson / Zim Mathematics is +10 years old now, with many Zim Math – Creative Math posts on Math Forum during that time!

Happy 20!! Math forum.

Happy Birthday Math Forum

Thank you for enriching my classes and inspiring my teaching with Problems of the Week, Ask Dr Math, Math Tools, and creative activities.

Cheers!

A very belated happy birthday to The Math Forum! You have done so much for many of us these past 20 years. I know you’ll be around for at least another 20, and I hope I’m around to continue to enjoy your great services.

Happy Belated Birthday, Math Forum! I am so glad I got to help with the Trig/Calculus Problem of the Week and the Discrete Math Problem of the Week. The world was my classrooom for the year I was on maternity leave and the variety of responses and approaches kept my mathematical mind active!

As always, I’m late! But for all of these years (only 18 for me), you’ve been a very important part of my life. Thank you all so much. With many hugs and much love, HAPPY BIRTHDAY!

A very happy 20th birthday to the Math Forum!

I started teaching in 1994, and the Geometry Forum––and then the Math Forum––was always the first place I looked for help and inspiration for my teaching. Now that I’m out of the classroom, your Ignite talks and newsletters continue to inspire me. I love both what you do and how much fun you have doing it!

Congratulations to Gene, Steve, Annie, and Jay (all appearing twice) and all the others who have worked for and with the Math Forum over the years. Thanks to the Math Forum, I am a better reflector, connector, communicator, noticer, wonderer, listener, and ultimately a better teacher. Thanks!

Congratulations to all of you for everything you have done to make the learning of math more interesting, more fun, more challenging for so many students, and teachers too! I’ve enjoyed my opportunities to work with you, doing Sketchpad PD with Annie, having Suzanne visit my Math Methods class, presenting Ignite! sessions with Steve, Max, and Annie at the recent NCSM, and all our other interactions over the years. I regret that you didn’t yet exist when I was teaching high school math (I’d have been a better teacher as a result), but it’s great that you’re there for the current generation of math teachers and students. May your next 20 years be as exciting and productive as the last!

From the International Seminar at the Park City Mathematics Institute, I want to wish you the happiest of birthdays. Thanks for all that you have done and continue to do.

OK–a “belated” birthday wish (don’t suppose I can blame it on the “slow mail to Canada, eh??”

A very Happy Birthday to the Math Forum, and all who make it the incredible resource that it is!! I couldn’t even begin to identify all the ways the Math Forum has helped me–from using the POWs in my classes, to having my pre-service students mentor, to what I’ve learned as a T2T associate, …

Keep up the amazing work!!

Happy Birthday Mathforum!!

I remember my online summer course in Algebraic Reasoning in May of 2006, I think. All the work done on the Reflection page inspired me to urge my students to start their own math journals. It also helped to add a lot more meaning to the discussions in clas, especially after addressing a question with multiple ways of getting to the answer(s).

Some of the students’ reflections proved actually quite insightful for me too and helped me to appreciate their line of thought, thus strengthening my bonds with them.

I am looking fwd to attending a math camp at Drexel where teachers from various parts of the world will participate and sit around a bonfire singing math songs and enacting math plays!!!

Happy Birthday Math Forum! Thank you for all that you have done to make math fun for teachers as well as students. The Math Forum has definitely changed my teaching style – for the better! My favorite piece to problem solving is “noticing and wondering”. It is so inspiring to hear students, on their own, talk about problems they come across in their textbook using, “I notice that…”.

May you enjoy many more years of continuing to inspire us! Thank you!

Happy Birthday! Thanks for furnishing students and the math community with thought-provoking explorations. You have done more for rich discourse in the math classroom than you can imagine. Can’t wait to see what’s next!

I still have my Math Forum T-shirt from nearly 15 years ago. Wearing it always brings back fond memories of a brainstorming and hanging out with a warm and friendly group of passionate mathematicians. I’m so thrilled that my kids are now old enough to start benefitting from your materials.

Here’s to hoping we have another excuse to collaborate soon!

Congratulations on 20 years.

I found Dr. Math in 1996, asked a question and got a great answer from Dr. Tom. I haven’t stopped asking questions and finding new things ever since.

The Math Forum has welcomed me as a student, as a teacher, as a nudge (pronounced nudj), and as a colleague with such supreme respect. Beyond the math, beyond the technology, beyond all that is a group of people who inspire me every day.

Thank you and Happy Birthday.

Happy Birthday Math Forum!

And warm regards to all of you – put particularly Suzanne and Stephen. Against all odds and with new and challenging-to-use technologies coming out daily, you put together some of the absolute finest online seminars I have ever attended. I learned so much from every aspect – not just the math which was fantastic, not just the technology in the math which was mind blowing, but also the technology for presenting and the kind of community and communication it takes to run online resources. Congratulations and best wishes for a continuing future!

Happy Birthday! Congratulations and a sincere thanks to all the folks who made the Math Forum what it is and continue to provide the inventive and valuable services to teachers and students world-wide. You were 20 years ago, are today, and I am certain will continue to be the ONE-STOP-SHOP for all things mathematical on the web!

Let me echo previous sentiments, and say that with all the change in this world, the Math Forum is indeed the ultimate PLC. Thanks for being such pioneers, so inviting, so responsive, and so clever.

Totally in awe, always wondering,

Lynne

My math and science instruction has totally transformed after working with this incredibly smart, professional, fun and skilled group. In fact, working with MF changed how I interact with people in general when information is being exchanged. I listen differently and ask questions differently.

Thank you for all that you do. Happy, happy 20th birthday and many, many more. .

Wow, the 20th Anniversary. Twenty years in this Digital EXPLOSION age? Only superb folks can make this happen!! As a former employee, I know it is your exceptional enthusiasm, unwaivable dedication to education and all of the visionary, creative hard work to make MATH FORUM a great success.

The town I live now has one of the top math high school program in MA.

It is proud to see in their web site that Math Forum is one of their outside resources recommended. Your great efforts have made huge impacts on boys and girls.

Congratulations to you all! Wish you best luck!!

Happy Birthday, Forum!

It’s been exciting over the past two decades watching you structure so many different wild technologies into useful—sometimes profound!—new ideas in teaching and learning. 20 years from now, as I admire the “third generation” photograph of you joining the two above, I’m sure I’ll be able to reach into my browser and spin you left over right and head over heels in awesome 3D. But better than that, I know I’ll be able to count on you helping me understand not just *that* I could do this, but *why*.

Cheers

Congratulations! Thanks for providing such committed and high-quality service to the mathematics education community–and for having fun while doing so!

Congratulations! I have such fond and formative memories of working with the Math Forum team on e-Problems of the Week. What productive fun we had. Here’s to 20 more years!

Happy birthday to the Math Forum!

Happy Birthday! The Math Forum has been a favorite resource of mine for all of its 20 years. Thanks for all you have done and will continue to do!

I wonder where the Math Forum is headed for its next decade?

This year it will become an adult service at 21 years of age.

What transformative mathematical service will it bring the world?

Best wishes to the amazing Math Forum for a long and fruitful life

from the Virtual Math Teams (VMT) project!

Happy 20th Math Forum!

You’re a great group and the essential math education community.

You’re a model for us all.

Best wishes for the next 20.

I notice that the Math Forum has been around for twenty years. I notice that many teachers and students around the country owe their enthusiasm and their competence, in some way, to the work of the Math Forum. I wonder what new and exciting ways the folks at Math Forum will find to keep us all challenged! (I wonder how bleak and dreary the teaching profession would be without the Math Forum).

Congratulations to a wonderful group of people behind the (computer) screens. Problems of the week (especially the library!), Math Tools, Professional Development… QUALITY all around!

I notice my teaching practices, focused on bringing understandings to my students’ mathematical experiences. My students’ achievement and perspective towards problem solving improving every year!

I imagine this could only have been possible through working and collaborating with professionals who are so passionate and sincere about helping teachers gain insight into their pedagogy via technology, meta-cognition and just supplying inspiration.

I wonder what the next 20 years will bring?

And may I add, these are the some of the nicest folks I’ve had the privilege of working with!

All the Best!

Happy 20th Birthday Math Forum!

The Math Forum changed the way I teach! The people behind the Math Forum, the tools provided by the Math Forum, the PD workshops, and of course the Problem of the Week are all things that have made me a better teacher. Every day I use the Math Forum on some level in my classroom. My students are the best problem solvers and thinkers because of the things I have learned from the Math Forum.

Annie, Steve and Suzanne are three out of four in both pictures. I must not know the fourth person, I suspect the man with the beard.

Thank you Math Forum for providing math teachers with the resources and community to improve math education. I am happy to be a part of your journey!

Happy Birthday!

Looking forward to working with you as Goodwin College’s new Business Analyst (replacing Bob Sullivan) starting Monday, 6/19/2012.

Cheers!

Ted Faigle

Math Forum changed my life! It definitely changed how I teach. I learned how to help students become successful problem solvers. I am a part of the ultimate PLC thanks to the Math Forum with teachers from all over the country. The Math Forum has given me a new excitement for teaching. I can’t wait to see what the next 20 years entail. Happy Birthday!!!!

Hi there,

Greetings and Happy 20th Anniversary. I did an introductory online course couple of summers ago, but haven’t really been able to use the POW regularly. Though I constantly refer to and direct my students to Ask Dr. Math. I & my students (though they don’t necessarily admit it) find the Ask Dr. Math service a good starting point or an end to the quest itself

Thank you for continuously improving the site & related services, here is to another 20 years fi not more.

BTW my guess of the four people (wish could attache the photo) are in the “Back in the day!” photo, starting from the bearded gentlemen in the back the two persons to his left and the elderly gentlemen in glasses to extreme left. Hard to see clearly due to low image resolution and of course sorry I don’t know their names

Oh! so what is the price for the right guess… just kidding

Thanks & hearty congratulations to all.

Ok! can’t help not responding to myself Browsing through the fascinating timeline page, found the elderly gentlemen with glasses is -probably- non other than Gene Klotz the founder of the Math Forum, who was honored in April 2011 with the National Council of Teachers of Mathematics (NCTM) Lifetime Achievement Award for Distinguished Service to Mathematics Education -Ok I admit, copy & pasted the text

Someone correct me if I’m wrong

Needless to say a belated congratulation to Gene for the award. Setting an example for rest of us to aspire towards achieving.

I remember early in the Geometry Problem of the Week that my students were convinced that Annie was writing the problems to fit my class – every problem matched up with what we were doing. And then she came thru Seattle on a cross country trip and visited my class. And then they were even more convinced that she was setting up the problems just for us.

Thank you, Annie and The entire Math Forum Team for giving us such a rich resource to use with our kids. You are the greatest!!
