So excited! @Desmos is now integrated in EquatIO mathspace (equat.io)!! #mtbos #iteachmath #algchat #elemmathchat #mathchat #makemathdigital

Mathematizing London with secondary math colleagues. From early algebra and beyond. #iteachmath #mtbos #algchat

Summer academy algebra students engaged in a great open middle task from @mathequalslove #mtbos #iteachmath #algchat

Exploring generalized arithmetic, the notion of a quasi-variable (78 - 49 + 49 = 78), and their relationship to early algebra. #Matematikbiennalen2018 #iteachmath #mtbos #algchat

Created my own open middle problem to try tomorrow! @mjfenton @openmiddle #mathchat #algchat #openmiddle #wcmath

Shades of function carnival, what a great graph from chartr. #algchat

A student’s “proof” that got a spontaneous round of applause in Algebra 2 today. #MTBoS #algchat

99% of the time the Magnet Game is a giant disaster but we always have so much fun! #MTBoS #algchat #mathschat #mathchat

Congrats to our very own @KaraLouiseImm for defending her dissertation: Modeling where it matters: Redesigning mathematics education with adolescent girls of color. We can't wait to have "Dr. Kara" share her study with us all. #iteachmath #algebra #algchat #designthinking #MTBoS

Fun in algebra with factoring trinomials by playing Connect Four! So fun!! #MTBoS #algchat #mathchat

Possible #5OAB3 activity idea.cc @literacygurl .#elemmathchat #algchat

Absolutely love this problem as a higher level transformation question. #Mtbos #algchat #alg1chat #iteachmath

Tried @Fouss's version of Trashketball almost 8 years ago and it never disappoints. Simple, effective and fun. #mtbos #iteachmath #algchat

#MTBoS: Is there a way to solve this system on paper? I keep going in circles. #algchat

Great question from a non-routine problem solving workshop at MfA: . How many ways can you divide a square into a certain number of smaller squares? Is every number possible? . #MfAProud #mtbos #mathchat #Alg2chat #algchat #iteachmath

#MTBoS #ITeachMath #AlgChat. Would you ever encourage (require) students to use this technique to solve this problem? Would you assign this (textbook) problem for homework if it asked students to use this technique? Why or why not?

Ms. Vazquez, Mrs. Lowry and I are here after school doing algebra boot camp for our tigers who are working towards passing the EOC or the PERT #MathMonday #algchat #mathchat @tkhstigers

Here’s an upcoming COLLABORATION activity for my students in Reimagining Algebra:. I saw this on Facebook. Why does it work?. #iteachmath #mtbos #algchat
