I agree with n2n2n...
Glyphs are ways to collect and analyze data. I use glyphs to go along with our graphing unit in math.
For instance we just did jack o'lantern glyphs. If your costume had a mask your stem would point to the left. The eyes told about their costume type. The nose told their favorite type of candy. The shape of the pumpkin told us if a boy or girl had made it. ETC...
I hung about 10 of the finished pumpkins up, labeld them A-J and wrote out some questions for the class to answer using the glyphs.
How many people are wearing a mask with their costume?
Which jack o'lanterns were made by girls?
How many people will be wearing a scary costume?
I hung up the next 10 on another day for them to answer more questions.
