I took yesterday off of blogging because of being overwhelmed with todo lists for work. Fixed that. Yay! So, another #BlAugust post for me.


OMG! I also earned a “Star of the Week” from Meg Craig for this post! Wow. That is an honor coming from her. She also made a shortlink for the page: I guess I better keep it updated!


Stars of The Week

Okay, on to the post.

I attended a board meeting of the local math group last night. Some of the most amazing educators in my region (not just my county), and it is a pleasure to work with all of them again. I am on the board as the Higher Ed Representative, which is a good fit.

During the course of the meeting, a call was put out by a member for resources, activities, and other things for the newsletter. Of course, I volunteered a list of 5 or so things off the top of my head from the MTBoS. There was concern about the amount of time it would take to “find” these resources, so I volunteered fix that.

This collection of #MTBoS resources is here so I can find it easily in the future and to provide a page where other teachers can be directed.

First off, what is the #MTBoS? The hashtag stands for Math Twitter Blog o’Sphere. Dan Meyer has an interesting take on the MTBoS.

Sites that are ‘organizational’ in nature:

These sites try to organize or provide structure to the #MTBoS in some way.

Exploring the MTBoS: A site created by math teachers to help organize, explain, and yes, explore the MTBoS.

Welcome to the MTBoS: A site created to welcome teachers new to the MTBoS. It gives them support, some guidance, as well as helps them find some good tweeps (Twitter peeps) to follow and get to know.

A dedicated MTBoS search engine: Have you ever wanted a lesson on XXX, but googled it and came up with a bunch of crap? This search engine searches only math teacher blogs, K-12, and will pull up lessons that are tried and tested. If the lesson sucked, the blog post will tell you that, and how to improve it.

TwitterMathCamp: An annual conference that meets in July to connect teachers. It is PD for teachers, by teachers. It also has an archive of blog posts from every year. In addition there is a wiki of sessions, My Favorites, and Keynotes.

The MTBoS Directory: This site lists teachers who are self-identified as members of the #MTBoS. Want to join? Just submit your name. That is all it takes. It has a map of members to help you find local math teachers, as well as multiple ways to sort and select people.

The hashtag #MTBoS on Twitter: Ask a question relating to math or math teaching using the hashtag, you will get an answer.

A Facebook MTBoS group: Another way to connect with math educators

A Padlet of “High Fives” for others in the #MTBoS created by Sam Shah. He is amazing. The “High Five” is relevant because of the speech I gave at TMC15.

A Chat list of Educational Chats: They list themselves as “official” but of course there is no such thing. It is rather comprehensive, and although the chats change times each year, it is pretty complete and accurate.

A MTBoS LiveBinder: This binder collects and organizes resources for the MTBoS. There are a lot of different links in this binder.

Resources / Activities created by the MTBoS (many are crowd sourced, submit your questions too!)

  • Global Math Department: Every Tuesday evening, a presentation by a different math educator on a relevant topic.
  • Daily Desmos: Different Demos challenges every day. 6-12
  • Yes, Desmos is a company, not a person. However, they are an active member of the MTBoS!
  • Estimation 180: Andrew Stadel’s site with different estimation challenges for each day of the year. K-12
  • Visual Patterns: Fawn Nguyen’s site with different visual patterns, challenging learners to create the equation / expression for it. K-12
  • Math Talks: Fawn Nguyen also curates this site which prompts to get your learners talking math. K-12
  • Which One Doesn’t Belong: Mary Bourassa’s site that poses the age old question. K-12
  • Math Munch: Justin Lanier’s site that has lots of fun, engaging lessons. K-12
  • Would You Rather? John Stevens asks the simple question, would you rather have this, or that? Justify with math. 6-12
  • Fraction Talks: A great visual way to get learners talking about fractions. K-12
  • Collaborative Mathematics: Poses questions to get learners engaged with each other about math. K-12
  • Open Middle: Robert Kaplinksy created this site to collect open middle questions. K-12
  • Math Mistakes: Michael Pershan is fascinated by what teachers can learn by looking at mistakes. K-12
  • Talking Math with your Kids: Christopher Danielson’s passion for doing math with little ones is celebrated. K-6
  • Math Arguments: The Math Curmudgeon curates problems to create math arguments in your classroom. 7-12

Teacher resources (not for learners necessarily)

And this is before we get into lessons from: links created to archive and store awesome lessons.

  • – Managed by Jedidiah Butler, a way to store all the awesome things created by teachers around the world with Desmos. Add yours too!
  • – Created at the Descon16 by Julie Reulbach to keep track of the amazing Card Sorts her group was creating. Add yours too!
  • (this page so I don’t forget it!)

These are just a few of my favorites.  For more activities, teacher created materials, sites, and just all around engaging stuff go to the Welcome to the MTBoS site.

I hope this helps. Now that I have it typed up, I am passing it along to teachers in my region for sharing as well.

Have a wonderful day!

In my Feedly this morning popped up the article by Larry Ferlazzo called, “Disappointing NY Times Article On Teachers & ‘A Sharing Economy’.” Okay, let me be more blunt. I am not disappointed in the NYT, I am frustrated and a little ticked off. It stems from this article in the NYT: A Sharing Economy where Teachers Win by Natasha Singer.

Read the article. I call foul AND shenanigans. How much did TeachersPayTeachers pay for this fluff piece that was nothing more than an advertisement for teachers selling out other teachers.


Maybe it is because I am active and love the #MTBoS (that is the MathTwitterBlogo’Sphere, if you are not familiar with it.) I embrace the sharing, the collaboration and the freely giving of resources that the math teachers do on Twitter, their blogs and the internet in general.

The article should have been titled, “A sharing economy where teachers win, but collaboration dies.” Sure, some teacher just made $1000 by selling her lesson plans to a 1000 different teachers for a buck. She won, but collaboration died. Is she seeking feedback from people who have used her lessons? Is she improving them by discussing and talking about how others have used them? Probably not. It is in a store, and people are buying it. There is no reason or need to improve it.

Meanwhile, in the #MTBoS, teachers are making, sharing, improving and resharing lessons all the time. They are coming together to make better lessons. And then, they talk about these lessons, which spawn more, better lessons. This is a collaborative community where ALL teachers win, and more importantly, our learners win. And our learners continue to win. Over and over again.

Seriously, look at the amount of resources freely created and given away.

First up, websites created by teachers collaborating:

  • Let’s start with the MTBoS Directory. No one claims this is an exhaustive list. It requires teachers to add their names to it, but there are currently 344 teachers in the list, all with an online presence, and all sharing things.
  • – created by Tina Cardone and teachers all over the #MTBoS who contributed tricks. You can download the most excellent book for free.
  • Fawn Nguyen’s Visual Patterns and Math Talks. Both are excellent sites. I have used the Visual Patterns site frequently in my high school classroom, and am working on learning more about Math Talks and implementing them in the college classroom where I am now.
  • Would you Rather Math is a site I used regularly in my teaching as well. Great questions, created by and curated by John Stevens.
  • Michael Pershan’s Math Mistakes. See an interesting math mistake? Submit it to this site and have a discussion on the thinking the learner made while making the mistake. We can learn more from mistakes than we can from correct work.
  • Dan Meyer’s Google spreadsheet of 3 Acts lessons. More on this to come. I am working on an idea taking shape out of my current position as a Master Teacher with a UTeach model school.
  • Mary Bourassa’s Which One Doesn’t Belong. So Mary saw Christopher Danielson’s great shapes idea, and realized that there was some amazing math thinking that could be done. BOOM, another collaborative website created.
  • Open Middle Dan Meyer introduced the idea, Nanette Johnson, Robert Kaplinsky and Bryan Anderson ran with and created the platform.
  • Desmos Activity Bank A site created by Jed Butler out of the need to share Desmos files, first showed at TMC15 at Harvey Mudd College.
  • MTBoS Activity Bank created by John Stevens (second time his name is on the list) to collect and curate some of the awesome materials created. Anyone can submit their own, and searching is easy.
  • The MTBoS Blog Search also created by John Stevens (I don’t think he sleeps). This site allows you search the blogs of a long list of math teachers for lessons, content, whatever you are looking for.
  • Robert Kaplinsky has a Problem Based Search Engine, to find those specialized lessons that are, you guessed it, problem based!
  • The Welcome to the MathTwitterBlogoSphere website has a further collection of collaborative efforts that includes some of the above but is even larger.

But that isn’t even all of it. There are teachers who are collecting curriculum, links or materials and sharing it all back out; lock, stock and barrel. These teachers have “Virtual Filing Cabinets” full of lessons that have been tried and tested, re-written and shared back out. Some call their pages VFC’s, some are just curated sites of materials.

And then there are great organizations giving away curriculum:

  • Illustrative Mathematics, free ever-more-complete curriculum that is CCSS aligned and incredibly high quality.
  • Shells Center/Mathematics Assessment Project, good as lessons, problems or assessments. I forget about this site until I am desperate, and then kick myself because it is just so good and thorough.
  • Mathalicious has free lessons and paid lessons. I have used them in class. They are worth paying for!
  • Igor Kokcharov has an international effort in APlusClick. Lots of great problems and lessons.

And this list is FAR from complete. It is what I pulled together in 15 minutes of thought. And this list does not even begin to talk about the 180 blogs

So, NY Times and Natasha Singer. You blew it. You didn’t show teachers winning, you showed teachers selling out. If you want to see winning teachers, click on any link above and read their sites.

The above are all winning teachers. TeachersPayTeachers is an example of teachers losing out on this kind of collaboration.
