Day 133 – Math 8 is Back!

titled square

Math 8 – Today was my first day back with the grade 8’s, with my awesome student teacher, Jenny Yim, finishing last week.  She did a great job.

Today I wanted students to work with titled squares as an alternative to the Pythagorean theorem.  I framed it like this:  “I don’t trust 2500 year old Greek mathematicians.  Especially ones that throw their friends into a lake because they think that there is something called an irrational number.”

Once students are comfortable with using the titled squares I’ll show how it can be used as a proof for the Pythagorean theorem.
