Happy Monday everyone! I’m back at it today on the blog with a new volume of Monday Must Reads, my weekly-ish attempt at capturing the amazing ideas of (mostly) math teachers on twitter. I hope you find at least one idea that inspires you in this week’s round-up.

Have plexiglass up in your classroom? Brianna Orozco shares an easy and fun way to decorate it for the holidays.
Jen M shares how Mrs. Summerer using plates for counters on a giant ten frame. Ideas like this kinda make me want to teach elementary school math…
These haikus from Mr. McCabe’s students are fabulous as well.
This student work from Mary Zastrow‘s Circle Project is impressive.
Ed Southall asks – Which of these are squares?
Mark Kaercher is making the best of not being able to use whiteboards by posting step-by-step origami instructions.
Mark also shares a lovely looking WODB problem involving complex fractions.
Elissa Miller shares a way she encouraged students to reach out to teachers and say thank you for Thanksgiving this past year.
I really like this twist on the traditional right triangle trig questions from jshm.
I’m sharing this image of methods for multiplying binomials from Dan Pearcy so I can find it again in the future. If you’ve read my blog, you know I adore the grid method (box method). I’ve never seen the tree method, though. Interesting!
Nataly Riera shows how to use Jamboard to recreate a math joke worksheet. Clever!
I love Skyscraper puzzles, but I haven’t found a way to do them this year since we aren’t allowed to share supplies or really even use manipulatives. Erick Lee has made an amazing Desmos Activity Builder version that looks super awesome.
Becky Hall highlights a lovely logs task from UndergroundMath.
Emily Sliman even created a Desmos draggable version of the logs puzzle.
Melinda Lyon shares an fun practice/error analysis activity she calls “Trick or Treat.”
Debbie Hurtado shares a function map she created that was inspired by Hayley Cain.
I really like this Tic Tac Toe structure from Rik Rowe for connecting different concepts related to linear functions.
Until next week, keep sharing your awesome ideas! Want even more ideas? I suggest checking out previous volumes of Monday Must Reads!
