Great App for Teaching Symmetry

Recognize this face?  I use this image to teach my fourth grade students about symmetry.  Of course, Abraham Lincoln was known for his asymmetrical face, and the above image showcases lines of symmetry beautifully!

(An added bonus:  I teach at Abraham Lincoln Accelerated Learning Academy, so my students are extra enthusiastic about this lesson!)

In the past, I've had my students snap photos of each other and then run off multiple copies plus "flip" copies so that we can create similar images of the students with a left side+flipped left side image, the original photo in the center, and a right side+flipped right side image.  The kids love this activity so much, but it is REALLY TOUGH to accomplish in a single math period.  It also can become a tad confusing and usually it takes a student a few tries to get this correct.

In the end, we put the images onto a large set of classroom posters entitled:  The SymMEtry of ME!  When posted in the hallway, they're a real crowd pleaser.

I'm always on the lookout for ways to incorporate great apps into my curriculum, so imagine my surprise when I found an app that could take a student's photo and create symmetrical images...

Enter Face Symmetry Tester HD for iPad.  This FREE app allows the user to take a photo and then create images with the left side and right side of the face.  What used to take my students over an hour now takes 20 minutes for a class of 25 kiddos.  PLUS...I can make a cool slideshow of the students since the images are saved with my photos.  How cool is that?

Here's a sample of one of my lovelies...Rylee!  This is what she created:

Face Symmetry Tester HD is an excellent resource that you and your students are sure to love!

  1. What a time saver! I used to do it displayed on the big screen for the whole class, and it took forever. Can't wait to try it out!
