Geogebra!

In class today we received three work sheets to use on a website, or tool called Geogebra. I absolutely love this program. There are so many different, fun things you can do with this in the classroom. On our first worksheet, we were asked to create a triangle, and then using the different tools, we created a vector. and translated the object to another location on the opposite side of the Y axis. This was so helpful for a few different reasons, it showed the even though you move something, and translate it, the size of the object does not change. It really just "pushes" the object to new coordinates.

We also did some rotation activities. We were asked again to create a triangle, and just rotate it around the graph and show that the size does not change wherever you move the shape to. I really had so many problems with the rotation as a child. I am so happy I can see and understand it now. I wish I would have had a better teacher to help explain this to me, so I understood it back then. * Note to self, when a teacher: plan lesson so that the children actually understand it! Now if only I could understand nets...That will never happen.

Here is the link to Geogebra! The program is free! Download it!

If you look up images of translation, make sure to classify MATH. Otherwise DNA translation comes up. (Ha-Ha)
