Reflecting Ordered Pairs Across the Axes: A Hands On Activity Using Mirrors

It has been a while since I have written a blog entry. (Snow days and state testing has backed a lot of my lesson planning up). I am very excited to write about a recent lesson that I completed with my students that involved reflecting across the x and y-axis.

In this lesson, students discovered the mathematical patterns behind reflecting ordered pairs and collections of ordered pairs across the x-axis and y-axis. The students used mirrors to help them see what was happening. It was a lot of fun watching them discover this and it was rewarding to even see my lower ability classes coming up with some amazing observations. (View the video to see this lesson in action.)

Students started out with a short video showing them how to use the mirrors to reflect across each axis.
Here are some glimpses of some of the notes sheets that were featured in the above video.

A similar lesson to this would not be difficult to create, however if you like what you see on this blog, the lesson is available at my TpT site and can be viewed here. Thank you for taking time to view this lesson, it was very fun to teach and the students got a very good understanding of it.
