Symmetry Selfies

Woah.. has it really been this long since I have posted a new blog post? I have been so busy finishing up important lessons with my kiddos that I haven't had time to share all the fun we've been having! :) First, let me just say, our MAP data is complete for the year, and I couldn't be more impressed with the growth of my students. They truly are the "best class ever" as I tell them all the time! They're a good bunch of kiddos.

One of the final things we study in 4th grade math is Geometry. By this point in the year, students brains are tired, folks. It's about that time when we begin prepping students for the lovely end of the year tests, and we are all just..... well... TIRED!! TIRED.. TIRED.. TIRED!!

But hey.. the show must go on...

So.. SYMMETRY. There are lots of super cool ways to teach symmetry in the classroom: Geoboards, mirrors, finish the picture, etc... One of the more engaging ways, from what I have found, however, is this cool little thing I came up with during my student teaching... SYMMETRY SELFIES!! (Although... I didn't actually call them selfies way back then.) Uh.. yea.. anyway..

So basically, I took photos of each of my students, had them developed, cut them in half, and taped them onto a "symmetry selfie" template. I introduced symmetry to the kiddos, showed them some examples using some cut out letters of the alphabet (the old folding technique), and revealed their pictures. They LOVED this. I had them working on their selfies during a center. It doesn't teach them everything they need to know about symmetry, of course. The standard actually says,

CCSS.MATH.CONTENT.4.G.A.3 Recognize a line of symmetry for a two-dimensional figure as a line across the figure such that the figure can be folded along the line into matching parts. Identify line-symmetric figures and draw lines of symmetry.

But hey.. it's a great introductory lesson to get them engaged, motivated, and creates some positive geometry neuroassociations!

And as always.. HAPPY TEACHING!

  1. These are so cute and smart, my team mate has done symmetrical Christmas cards for years ~ this is cute too. Thanks for sharing!

    1. Thank you! The students really enjoy it. It's a great intro to symmetry. :)
