One of the teachers at my school was having trouble finding some 3D geometric shapes to make her test with, so I made a few for her. Then one thing led to another, and now I have a whole bunch of clip art that I thought a Math teacher might find useful. I have used these images to create tests, task cards, scavenger hunts, and practice work for Math small group and centers. This file is not meant to be used as a presentation.

In this lesson, the students have to navigate their triangle through a video game environment to reach the goal by using translations. The first part of the map has outlines to show where the triangle should be moving. In the second half, the students get to choose their own route to navigate the underworld and save the princess!

About the store

Experience

I taught Algebra/Geometry in High school for 4 years. I also have been teaching pre-AP Algebra and 8th grade Math in middle school for the last 6 years.

Teaching style

Technology heavy teaching style. I made my own virtual whiteboard with a Wii remote and I use powerpoint presentations and things like the eInstruction remotes all the time.

Awards & shining teacher moments

My students think I'm awesome, does that count? hehe And the old saying about always a bridesmaid and never a bride applies to me and the teacher of the year voting at my school. They like me enough to keep putting me on the ballot, but I never seem to win. Personally, I think it's because I'm in a portable building and they think less of me because of that. :)

My own education history

BS in Math from the University of Texas

Additional biographical information

I am a native Houstonian who is back home teaching math to at-risk kids. This is definitely NOT what I saw myself doing when I was a student, but I love every minute of it. I am also a father to an awesome, rambunctious 3 year old boy.
