Stay in Shape! Convex and Concave Polygons!

            We are coming to the end of our math trek and I feel that I have learned a lot through both of the math classes I have taken over this summer. The only thing that I would change would be that we could meet together face to face. I know their faces from the pictures I see, and I know that we will all finish the trek together and that makes me very happy. We are on our way to becoming Elementary educators. We have to make sure that we stay in shape ourselves learning new methods of teaching and also knowing what we struggle with most. Most of all we need to work together so that all of our students finish the trek strong.

On the math Trek we need to stay in good shape by knowing what content will be coming so that we can keep moving forward and making progress on our trek! We have to make sure that all of our students are doing their exercises or they will get out of shape on the math trek and then fall behind.  

Today we are going to be covering more terminology and we need to know the names and facts about differing shapes in math. We are going to be learning about concave and convex polygons. I will start off my giving the definitions of both.

Convex: polygon that has all interior angles less than 180°
(Result: All the vertices point 'outwards', away from the center.)

Concave: A polygon that has one or more interior angles greater than 180°
(Result: some vertices point 'inwards', towards the the center.)

When you feel that you have a firm grasp on convex and concave polygons please try this fun game!

I hope that you have enjoyed my posts and that I have helped you on your math trek! Math is challenging, but it can also be very fun! We just have to help each other along the way, and help our students succeed and finish strong so that they can successfully make the trek of life!
