I was introduced to glyphs about 15 years ago when I went to math workshop. I was amazed at how these simple drawings contained so much data. I knew that I had to use them in my classroom.
One of my favorite glyphs, in one of the books, was the baby block. I used it many times when doing student-led conferences. It was a way for parents and children to share information together about when the children were babies. It was also a great way to introduce the parents to the power of a glyph for collecting data.
I highly recommend giving them a try.
