This week 4th grade students will be introduced to symmetry by watching this video:

Students will then get with a partner and move to a table in the computer lab where a straight line has been drawn using a dry erase marker. One student will create a design with fractiles on one side of the line. The partner will complete the design on the other side of the line by mirroring the image to create one line of symmetry. The original creator will take a picture with an ipod and email the photo to themselves to post on their blog. Now the partner will create the design on one side of the line and let the other student complete the mirrored image. The original creator will snap a photo with an ipod and email that photo to themselves to post on their blog. The instructions for this lesson are posted in Edmodo with the accompanying tutorial video below.
