#### 1 Hook

If you like playing with shapes and building things then you will love geometry! Let's start with some basics by reviewing some shapes and their properties!  Let's check out StudyJams!

Then let's check out TRIANGLES! http://studyjams.scholastic.com/studyjams/jams/math/geometry/classify-triangles.htm

#### 2 Activity

Now you are going to create some polygons using the Geoboard App.

Make three TRIANGLES.  Can you you label them?  Where are the sides? How many angles are there? Take a screen shot of your Geoboard work!

Next, create three QUADRILATERALS! Can you you label them?  Where are the sides? How many angles are there? Take a screen shot of your Geoboard work!

#### 3 Demonstration/Sharing

Now it is time to show what you have discovered!

Using your Skitch App, create a mini poster with your Triangle Screen Shot.  How many different properties can you label?  For example: label a line, a segment, an angle.

Next, create a mini poster using your Quadrilaterals Screen Shot.  How many different properties can you label?  For example: label a line, a segment, an angle.

Feel free to go back to StudyJams, or use a math reference book to help you label your pictures!  Be creative!
