Monday Must Reads: Volume 91

I can’t believe it is already Monday again and time for the 91st volume of Monday Must Reads! If this is your first experience with Monday Must Reads, it’s my weekly-ish attempt at capturing the amazing ideas shared by (mostly) math teachers on twitter. I hope you find an idea or two to use in your own classroom or to share with a coworker.

I love how Dana Harrington not only engaged her students with the classic Four Fours problem, but she also got parents involved! What a brilliant way to introduce parents to Desmos, as well!

Using Geometric Transformations to Solve Puzzles

Sarah Furman shares an absolutely brilliant activity where she combines student knowledge of geometric transformations with puzzle creation. Students had to create their own puzzles similar to Cover the Duck, Cover the Heart, Cover the Camel, etc. Then, they had to use geometric transformations to describe the solution to the puzzle they created. I am just blown away by this activity.
