My BTC professional development during in-service week was a success! Thank you @Wipebook for sending me a set of wipebooks to use in my session. They are also providing a free flip chart via raffle to one of the participants!

[Ethan Tannen @MrEthanMath]

@cdelacruz314 @pgliljedahl @Wipebook Thanks!

[Aleda Klassen @aledaklassen]

Here are 4 sketchnotes of the 4 toolkits from @pgliljedahl's #thinkingclassroom.

These versions now have a better citation of the book.

I hope they inspire discussion about how to make learning more accessible to more students!

but the book provides a robust framework that has laid out every essential detail. Beautifully illustrated by @wheeler_laura makes it an even bigger joy to read. #MTBoS #iteachmath

One of the most exciting/energizing things about teaching is taking the summer to learn and become a better teacher. I'm inspired reading @pgliljedahl Building Thinking Classrooms in Math. Some practices I have implemented over the years and heard about at conferences... (1 of 2)

@talljerome what software do you use to make the AP Classroom Calculus videos? They are great! Thanks!

[Ethan Tannen @MrEthanMath]

@whyy are you going to play the pieces from your summer program participants on the air? If so, when? Thanks!

[Ethan Tannen @MrEthanMath]

The Mathematical Hydra task on the last day before break! Very impressed with how my students engaged with this problem and the different approaches they took!

After months of work, I'm going to pull the trigger and predict the election. Here goes nothing.

New post!

Some three-act math led to a lot of student enthusiasm with the girl scout cookie problem Dan Meyer showed at #NCTM created my own video and problem shortly after.

@thephlschool @jaketapper Hi TPS, check out my new teaching account here @MrEthanMath

@cmmteach @PIspeak @calcdave @marvelousmcc My understanding is that roots are the solutions for a quadratic expression set equal to zero. Otherwise, any (x,y) coordinate pair is a solution to a quadratic equation written with two variables x and y.

I've been really enjoying https://t.co/6DVAPsPCpK for visible random groupings in my math class. Thank you @MrsStevensMath for putting me on to it at #NCTM! #mtbos

In the woods, student says "there's a lot of math in nature. The symmetry of leaves, the slope of sightlines, the parabolic path of objects in free fall..."
