**Post Contents**hide

I can’t believe that the last Monday of the school year is finally here. We have semester tests today and tomorrow followed by a professional day on Wednesday. Then, the 2017-2018 school year is officially OVER! This means I can finally start thinking about ideas for the classes I’ll be teaching next year: Algebra 2 and Pre-Calculus! So, if you have any great ideas for teaching those two classes, send them my way!

Here’s my round-up of must-reads from the past week of Twitter.
