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. The idea is that you can copy/paste whatever you need from here a

Scavenger hunts are a great way to get your students up and moving while working on their Math skills! All of the problems in this scavenger hunt start with a fraction and require students to find its decimal equivalent. The fractions are more complicated and require simplifying/long division and more of the answers are longer or repeating decimals. If you'd like some more basic practice about converting fractions to decimals, then click this link to check out my scavenger hunt about Converti

This is an animated presentation that attempts to show the reasons for the area formulas for some of the basic shapes. I originally made it because I thought that if students could see where the formula for the area of a trapezoid came from then it wouldn't seem so intimidating to them. The slides have minimal on-screen text because they were meant to be used to facilitate teacher-classroom discussion. The 2nd half of the presentation shows some ways to deal with areas of non-standard p

This is a presentation/game for identifying 3d shapes based on their nets. The game is designed to have 2 students stand by the screen with fly swatters (I made my own out of meter sticks and construction paper). There are a number of nets on the screen and the students are given the name of a shape and they must find the correct net to "swat".

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.
