Sooooo, how many sides do you think a quadrilateral have?

Nice! You're catching on quickly! The force is strong with you! Now, please watch the following video AT LEAST one full time, if not a few times. It will give you a good idea about specific types of quadrilaterals, and their characteristics.

You do not want to miss this next video. It's LIT!!!!

Complete this practice sheet to sharpen your skillz!

Identifying Quadrilaterals

Pssst!! Have you written anything down in your notebook? Did you take notes while watching the video or completing the practice sheet? If you didn't, why don't you take a second and write down all the different shapes your just heard about. Write one quick characteristic about each one as well! That's good note taking!!
