Had the awesome opportunity to do some great thinking with @jamestanton today. Thanks for the problem solving experience of why 3x4=18, )considering intersections of lines)! Now if only my ceilings had a more geometric design…

@LetsLearnCalc @CCreightonMath Agreed, we walked through it today and talked about why it works. I also took the opportunity to try to show how the thm. would be presented in a textbook and how to work to understanding through that vocab/jargon/form, as reading textbooks a skill!

@ed_euclid @CCreightonMath The question I constantly struggle with is: Is there value in working through the algorithm? Finding factors, evaluating functions, both great skills, but the outcome of the RRT is so limited.

Anybody else have the twice a week “Why do we teach this?”crisis?

@LetsLearnCalc @CCreightonMath I just had this exact moment. We are currently going though polynomials. I have a harder time with the rational roots theorem then synthetic division, as synthetic at least has a purpose to break down polynomials. Rational root is so constrained/limited to a specific set of poly.

@CCreightonMath Exactly! For me, the calculus story is easy to tell, everything before that is messy. The conversation I just came out of was a something about precalculus. Namely asking if the rational roots theorem, synthetic division, and memorizing the unit circle are worth the effort.

@ProfKinyon @WanderingPoint I was curious how the secondary math teachers were represented… **30 year old, high school math teacher**

@RileyMathClass @MakeMathMoments Welcome! It’s possible & makes teaching math more enjoyable/rewarding. Twitter is where I started my journey. I second a lot of the previous comments and also suggest Building Thinking Classrooms by @pgliljedahl who gives 14 practices to encourage student thinking and engagement!

I’m pretty sure I heard the last two guests on @MakeMathMoments mention learning from twitter. So here I am. Is it possible to make Algebra 2 engaging? I’m going to try. #MTBoS #ITeachMath #mathchat

First conference of the summer. Glad to do some math Ed learning :) #iteachmath #MTBoS

Today after a quick narrowing conversation of a Ss final project research topic (non Euclidean Geo), I gave him my small taxicab geometry book. He sat flipping through it for the rest of class. Looking forward to following up with him on Monday :) #iteachmath #mtbos

@vierheller_emma Our department got: HUION H610 Pro V2 Graphic Drawing Tablet Android Supported Pen Tablet Tilt Function Battery-Free Stylus 8192 Pen Pressure with 8 Express Keys amazon.com/dp/B07DPC98DT/… They were cheap enough that we could all get some and they have worked well. USB Not wireless

I’m introducing polar graphing/coordinates and parametric equations to my PreCalc/College Trig course. #MTBoS what are important/fun things I need to be sure to include? #iteachmath

@Desmos has done it again!! If I don't know what to make, I can just use the new R_{ecipe} function at desmos.com/calculator/xdr… to give me recipe ideas! All you have to do is type in R_ecipe and click the action button to get a randomized recipe. Thanks Team Desmos!

It’s hard to believe it’s been seven years of getting amazing and free PD via #MTBoS and #iteachmath thanks to all that give their insights. I have learned so much! #MyTwitterAnniversary

@mikeandallie I am thankful (as I am sure many others are) to have been ‘par’ of the journey via your blog. I have followed off and on for the last several years and now my journey is just starting with my 6,4, and 1.5 year olds :)

@NolanFossum Nolan, thank you for sharing resources like this! I just gave my ‘tradtional’ CA final this week and it made me feel hypocritical as I have tried to change my other assessments. I feel stuck in the middle of two systems how it has been (I was taught) and how it should be.

Here is the two part activity that students and I work through together. The first part is really hard, but the second is a huge eye-opener! teacher.desmos.com/collection/61b…

S responses after my fave College Algebra lesson of the semester. We take a look at a typical College Alg final and deconstruct what it tests and what it doesn't. We offer altern's that open resources and seek to highlight students' knowledge. Always powerful! Link in next/2

@adhestenes Let me know how it goes! I did it the lesson after doing the factoring thin slicing from the book. If you have any tweaks feel free to share my way too, I know it’s not a perfect sequence :)

I've been working on implementing #BuildingThinkingClassrooms into my A2 and PreCalc courses. Although it has been a work in progress, this thin-slicing process of having students turn quadratics in standard form into vertex form was one that went over well. #iteachmath #mtbos

Had a great time attending #CCTM21 today. Thanks @NolanFossum for your presentation on UnGrading!

@JennSWhite I’m feeling this exactly with my A2 and PreCalc classes. Sometime we all need that *collective sigh* kind of day :)

@fawnpnguyen Yea! Thanks so much :) I’m a high school teacher so I didn’t need it for classroom use for it at the time. But now my own kids are getting to this age and remembered it was a fantastic resource!

@ed_euclid Hi Andrew. This one? docs.google.com/document/d/1Pj…

#mtbos I remember around a year and a half ago there was a preK-8 doc floating around here that had math activities that parents could do at home with their kiddos. It was geared to gain number sense through play. I think it might have come from @fawnpnguyen anyone remember? TIA
