@mrpurdymath.bsky.socialWhat do you notice? What do you wonder? 👀
Different colored dots
19 of them are empty
126 dots
Every empty one tells a story, and none of them are random.
New slow-reveal data talk dropping this week!
What do you think the dots represent? Drop your answers 👇

@mrpurdymath.bsky.social3 months as an Amplify Desmos Math facilitator taught me: teachers learn math teaching by doing the math, not hearing about it.
Talk less. Let the math do the work.
What’s the best PD you’ve ever had, and why? @amplifyeducation.bsky.social #iteachmath #MathSky

@mathillustrated.bsky.social2017: K-12 mathematics education has undergone many changes over the past decades, sometimes driven forward by mathematicians, sometimes by mathematics educators. But in reaching this rapprochement, we have left out another group of experts... #iTeachMath
@mrpurdymath.bsky.socialWant to honor Indigenous Peoples’ Day in math class but unsure how?

@tommaths.bsky.socialWas shading the "unwanted region" the normal practice/convention taught before?

This has some advantages when dealing with many multiple inequalities

@dbarman.bsky.socialIn ChapelHill #mathCircle my kiddo led a group w/her #origami love. I worked w/my 1st-3rd graders on #FermiEstimating. Several est. bricks on a walkway, leaves on shrubs, people at a white coat ceremony,etal. I disproved one who said they go to 1000 homes at #Halloween. #mtbos #iteachmath #mathisfun
@rajraizada.bsky.socialHere’s a simple demo of a 2D linear classifier in @desmos.com, using a pseudo-inverse matrix.
I used to need NumPy for this. Now, with the new matrix features, it works in Desmos. Much better for being able to drag the points around!

@dbarman.bsky.socialI had a lot of #mathisfun with one of my 5yo students. We looked at counting including when items were missing, patterns including one where we included and discussed randomness, and partitioning. She brought a cool Lego(tm) structure and we discussed symmetry. #mtbos #iteachmath
@pwharris.bsky.socialIt’s Dig Pink night! Developing Mathematical Reasoning grades 6-8 arrived just in time! Two math teaching parents - what a great family Brianna!
@mathillustrated.bsky.social"There has been much alarm lately over the possibility that we are a backward nation, mathematically
speaking, just when skill in mathematics could mean survival."
Guess when (of course, you know there are multiple correct answers). #iTeachMath

@mrpurdymath.bsky.socialNearly 1 in 4 people in the U.S. speak a language other than English at home. 🌎 My new data talk turns real Census data into a MS math conversation that builds to one question: Who is missing? 👥 Tag a math teacher who would use this.
