Parallel Lines and Transversals

I wanted to share this document I made because I used this lesson on Tuesday with my geometry class and it worked really nicely.  I did it with them on a doc camera and shared their answers over the doc camera as well.  We all really enjoyed especially the last problem which was written about a student.  He really enjoyed the problem even though it poked fun at him.  I did a terrible job after this lesson though with reinforcing all the angle relationships and their names.  I just went over all the vocab- alternate interior/exterior etc. and had them do problems out of the book.  In my defense, I just didn't have time to do anything more exciting.  But at least we had a good intro to the topic I think.

The pictures came from  and   By the way, I'm still pretty new to this so is it best to cite pictures as I did above, in fine print below the picture, or should I try to restrict myself to only using pictures I myself have taken?

  1. If you're looking for more photo-oriented work to do with your geometry class around vocab, you may like this project I did with my students earlier this year. The project was created by teachers I met at the Park City Math Institute last summer.

  2. I actually did do this project at the beginning of this school year. I read about it originally on f(t), then traced it back to your blog, but I had to modify it a lot as we didn't have access to the technology you did. It was an amazing project. I had a lot of fun watching my students try to visualize the point, line and plane relationships. It really stretched their imaginations.

  3. how cool!
    Have you ever used GeoGebra? It's free and really easy to teach yourself. I'm slowly getting addicted to using it with my students.

  4. I just downloaded it. I haven't had time to really mess around with it a whole lot. I think it's going to take me a while to learn how to use it, but I like the idea of being able to make graphs really quickly. Up until now I've been making graphs for hand outs and tests by creating my own grids in Microsoft publisher- which is really time consuming, but I'm a bit obsessive...
