This is a lesson that failed the first time but through years of improvements has turned into a project that students love. If you teach rational functions, definitely check it out. #mtbos #iteachmath open.substack.com/pub/kristens...

This post is for anyone who puts in the work to try to figure out how to support every student: open.substack.com/pub/kristens... #mtbos #iteachmath

This is my go-to routine for building procedural fluency with my students. #mtbos #iteachmath open.substack.com/pub/kristens...

This is one of my favorite end-of-unit tasks for Quadratics. I love seeing students’ creativity, so I wrote a post about it! #iteachmath #mtbos open.substack.com/pub/kristens...

I've been using a new format for intervention that I had to share because it has totally shifted how I think of support for students. #mtbos #iteachmath open.substack.com/pub/kristens...

I have come to understand that being a math teacher is also being a language teacher. #iteachmath #mtbos open.substack.com/pub/kristens...

First post on the new substack is live! Diving into noticing and addressing student mindsets about math. #iteachmath #mtbos open.substack.com/pub/kristens...

This was a super fun conversation about how to build our students’ math vocabulary and why it matters. #iteachmath #mtbos open.substack.com/pub/hollykor...

Does anyone know about @desmos.com switching over the teacher site and activity builder to Amplify? All of my custom activities were gone when I tried to log in—it says I have authored zero activities. I really hope that isn’t the case! Any help is appreciated #mtbos #iteachmath

Great description of a way to implement Thinking Classrooms that combines inquiry with explicit practice. This combines them across days while I combine them in a single lesson but the idea is that students benefit from both types of learning. #mtbos #iteachmath open.substack.com/pub/adrianne...

I started doing this end of unit extension project for trigonometry and similarity where students can design their own roof truss. There were some pretty cool design this year! #mtbos #iteachmath

This problem was so much fun! It was really exciting to see how many different solution paths students could come up with to find the perimeter of the square. Beautifully knits together properties of trigonometry and Pythagorean theorem. #iteachmath #mtbos @illustratemath.bsky.social

I couldn’t agree more with @dylanpkane.bsky.social approach to online tools in the classroom. I use @desmos.com activity builder for my Warm Up questions each day because the batch feedback is so useful but I set a timer for 7 minutes and students close laptops before we debrief. #iteachmath #mtbos

Celebrate Pi Day in any subject! 𝜋 🎉 These engaging, informative activities help students explore pi’s history, applications, and more. #EduSky #ITeachMath

This problem was great! A student said: “Wait but I just realized it also works if you switch them! Sin(41) still equals cos(49) even though it’s a totally different value!” And then another student said: “Wait, does it also work for 30 and 60?” And the whole class was like YES! 🤯 #iteachmath #mtbos

We launched trigonometry today in Math II. I’ve been using this resource for years and it’s still my favorite way for students to investigate the ratios. Students walk away understanding where the values in the calculator “come from”. #iteachmath #mtbos www.projectmaths.ie/documents/T&...

I love teaching right triangle trigonometry. Just when my Math II students start to think that math has taken a turn toward abstract symbols and equations and is not “real” enough, trigonometry shows up with all of its lovely simplicity and real-world applications. It really saves the day.

Our Math Team has mapped the math language routines onto the Teaching Through Problem-Solving lesson format. Teachers can see where there might be opportunities to integrate a MLR into the lesson. MLRs are not add-ons. They are essential. #iTeachMath docs.google.com/pres...

I got back into blogging! Do we need a clear objective? clopendebate.wordpress.com

I believe there is a lot of merit to the idea that explicit instruction is highly effective when done well and is key to effective instruction. I also believe inquiry can be highly effective when done well and @mrzachg.bsky.social focuses on the ways it can fall short when not done well. #iteachmath

Here's why your education friends had a real rough one today. It's... it's the entire education data collection apparatus of the United States. www.edweek.org/policy-polit...

Who would have thought that I would by chance put a “someone who is wearing a red shirt…” protocol in a presentation in Kansas City on Red Friday before the Super Bowl 😂 #NCTMKC25 #mtbos

Really enjoyed hearing from Gail Burrill about ways to integrate AI with math teaching to empower students as learners #NCTMKC25 #mtbos #iteachmath

I have been thinking and writing about how accessible and achievable problems are a key part of building student self-efficacy in math class. They don’t take the place of complex tasks but provide an on ramp as students build confidence. #mtbos #iteachmath

I’m excited to meet other math folks and give my first in-person NCTM presentation at #NCTMKC25 !

How to count in base 2 on your fingers #math #ITeachMath #EduSky

I spent this weekend writing about the decimal lesson I taught on Friday. I really liked how it went. Take a look. I'm interested in any feedback. marilynburnsmath.com/decimals/com... #Iteachmath #MTBos

Excited to be presenting at #NCTMKC25 next week. My session “Student Response Protocols in the Math Classroom” is Friday at 11:30 AM. Let me know if you will also be there — I’d love to connect with other #mtbos #iteachmath folks!

And yet if we do all the breaking down for students then they will never develop those skills that mathematicians have. There much be a balance between inquiry and explicit instruction to allow students to explore and develop problem solving habits and achieve clarity of concepts. #mtbos #iteachmath

This problem always challenges students because they have trouble turning the triangles in their mind — see how they found two different scale factors? This year I finally realized I could turn this into manipulatives that they could actually turn and it was game-changing! #mtbos #iteachmath ♾️

One of my colleagues who is a first-year teacher and currently in grad school told me this morning that her professor assigned the class my @edutopia.org article about inquiry based learning and direct instruction to read, and I had a moment of “yes, I did that!” www.edutopia.org/article/dire...

I’m excited to have inspired this dialogue around how we can foster self-efficacy in our math students. Check out this post that is full of great teacher moves! One move I’ve used is repeating class mottos such as “1 > 0” which means that any small effort will get you farther than not attempting.

I came across a study that showed a strong correlation between student self-efficacy and math achievement levels using the 2019 NAEP data. This makes so much sense to me but then I had to ask: how are we building up self-efficacy in math? What ideas do people have for this? #mtbos #iteachmath ♾️

#MTBoS #iteachmath We hope to put a stats class in next fall. (HS, non-honors for seniors who won't be STEM majors.) Anyone have a book they like? Or is there an online version of something that would suffice? (Does MathMedic cover what we'll need?)

Hello teacher friends! It's a good time to think about how to get end-of-quarter feedback from students in a reflective & productive way. Here's my quick "4 Question" method: karendcampe.wordpress.com/2018/11/01/e... #MTBoS #iTeachMath #T3Learns #MathSky #MathsToday

Happy New Year! And a new blog post as a treat (a week earlier than planned). NEW Blog Post: ‘Stop asking if we should tell and start asking how’ Why does telling remain such a charged issue in mathematics teaching? Reframing telling through its functions rather than its form offers a way forward.

Everywhere I go, I ask teachers, "What do you wish society understood about your job?" If you'd like to chime in, I would LOVE to hear your thoughts via this form, DM, or email: forms.gle/xh8YkyKYWVyv...

Some favorites from the end of semester AP Stats projects. Students chose their own statistical questions to collect data and analyze. And nothing better than a positive review from a student 😁 #mtbos #iteachmath #statschat

So proud of ourselves! Our book is published! Well done @mathematicala.bsky.social and Priya Shah. #mathschat #maths

My favorite way to close out a topic — send a problem! This one was arithmetic or geometric sequences and they could write the explicit or recursive function for their partner’s sequence. A fun way to head off to break #mtbos #iteachmath ♾️

My latest piece is up on @edutopia.org ! www.edutopia.org/article/teac...

The “hollowing out of the middle” and how it mirrors the income distribution in our society is what caught my eye. Our educational system is structurally unprepared to push back against the inertia of an unequal economic system. hechingerreport.org/proof-points...

I wrote about how I use the @desmos.com data collection screen for a Fermi problem routine in my classroom www.edutopia.org/article/tips... and here is my Desmos collection of those screens: teacher.desmos.com/collection/6... Any other Fermi problem fans in the #mtbos #iteachmath ♾️ community?

A powerful indicator of math discourse: Who's asking the questions? When students initiate mathematical discussions and probe each other's thinking, we've created a true community of mathematical thinkers. #MathSky #ITeachMath #EduSky #MTBoS

Would you describe this as a graph of exponential decay? #MTBoS

🔥🔥My MathEd/#Iteachmath hot take🔥🔥 Before you read and start implementation of BTC, you should first read and try to implement ideas from the 5 Practices.

Very excited to share some writing about how I’ve combined inquiry-based learning with direct instruction in my classroom. I believe that each method serves a unique purpose in student learning. Also an excerpt from my forthcoming book(!!) #mtbos #iteachmath #mathsky www.edutopia.org/article/dire...
