hexies in the classroom

last evening while i was listening to the science teacher chat about my son at conferences, i looked over and on the door spotted this...

i was so excited to see the use of hexies. they're everywhere right now in the stitching world. i offered my appreciation for utilizing a well known quilt pattern in the classroom. of course, it really is the other way around. yet the young teacher played along with me and told me that his grandmother quilts all the time.
