I recently did this activity with Little-N and Big-S. I followed the presentation in the Geometry Album I downloaded from Cultivating Drama. We used plastic fractions that I purchased from Learning Resource. I wrote the meaning of each word on a card and drew one set of symbols. Little-N and Big-S drew their own set of symbols and used the fractions to understand the relationship between the shapes. When we finished I got them to draw shapes in their books and label them. The above book is Big-S's, her writing has come a long way and is now very neat :) as for Little-N I let him stick the definition cards in his book so that he didn't have to spend too much time writing them out. I hope one day his writing will improve.
I have made three part cards for this activity you can download them from here.
