I knew this trick (learned it with 2 digit numbers x 11) but never thought of the reasoning. Thanks!

@MCampbellEdu You could show your 8s this trick and then have them figure out why it works!

@MrshinrichsT Can't remember the grade you are teaching, so not sure if this would help your students.

As much as I loved this method, I have to applaud the reference of the T-shirt 💊
