Online Professional Development Sessions


Which One Doesn't Belong? is a website dedicated to providing thought-provoking puzzles for math teachers and students alike. There are no answers provided as there are many different, correct ways of choosing which one doesn't belong. Join Mary Bourassa to work through some problems and hear her inspiration for the site. The mic will be then be opened to attendees willing to share how they are using WODB in their classrooms.

Register to attend here here.

Want to learn a bit more about WODB before tonight's conference? Scroll down to check out Andrew Gael's article this week!
Last week (Tuesday, March 24th, 9 PM EDT) Norma Gordon shared formative assessment ideas illustrated using student "thinklets" (CueThink iPad app). If you missed out on listening & watching some actual student thinking, you can view the recording here.

Some Food for Thought...

You've estimated. You've graphed. You've argued and decided which you’d rather. Now you can figure out Which One Doesn’t Belong!


Mary Bourassa’s new website is “dedicated to providing thought-provoking puzzles for math teachers and students alike. There are no answers provided as there are many different, correct ways of choosing which one doesn't belong.”


This website, inspired by the work of Christopher Danielson, Chris Hunter, and Steve Wyborney, adds a wonderful new class opening activity to the already impressive list from #MTBoS educators.


Here are some of my favorites!

Good Teaching Is Good Teaching


Joe Schwartz’ recent blog post, No First Graders Were Harmed Playing This Game, reminded me that good teaching is good teaching. I have found myself saying, “Good teaching is good teaching.” many times this year. Just because many states have adopted Common Core and have encouraged teachers to shift their instruction toward more student-centered learning, it doesn’t mean we have to completely abandon everything we’ve done before.


Joe uses Marilyn Burns’ About Teaching Mathematics (2nd Edition) from 2000. He used it to get students thinking when playing a dice game. And that’s what’s important.

Common Core does not imply that we abandon instructional strategies and activities that were effective before. Good teaching is good teaching. If you have instructional strategies and activities that have been successful, take a minute to decompose what made them successful. List the key ingredients and move forward with Common Core using those key ingredients more often.


I love how Joe asks his students what they think about the dice game. Some were very insightful about the math. Some were not. Just like we are in crucial time to redefine the “traditional” classroom, we are also in a place to redefine student perceptions about math. For example, one first grader thinks that adults are better at math saying, “You know a lot about math and we don’t know a lot about math.” Gosh, I hope not. It would be a tragedy if I couldn’t learn about math from my students.

This past month I've been participating in @sophgermain's #shutupandduckface challenge to take a selfie every day and post it. While I'm neither here nor there staring at my own image, getting to see faces of friends across the country each day has been a delight.

In light of this, exploring the new MTBoS directory to see faces alongside interests and hobbies and then poking around the map to see dots across the globe is a delight for me. It's a great reminder of how, even with thousands of miles separating us, we're all just people working at being better educators and willing to support one other in that work.
