Geometry: Shapes, lines, rays

Recently I posted an activity to help students with the concepts of lines, rays, and angles.  You can visit that post here.  The students and I read together the book The Greedy Triangle by Marilyn Burns shortly after our activity and my students began to wonder about creating a circle.  If you aren't familiar with The Greedy Triangle, this book is about a triangle who decides he doesn't like being a triangle anymore.  He goes to see the shapeshifter who keeps giving him one more side and one more angle until he can barely walk since he is almost round.  He finally decides that being a triangle isn't so bad afterall.  It is a great story that the kids LOVE!   Some of my students began putting their lines they made (see the first post again) together to create different shapes.  I am almost ashamed to admit it but I've never thought to do this before during this activity. I was elated.  Here are the shapes we made:

So much fun!  They learned alot!  Visit my TpT store for some great math, reading, and writing resources!
