- Here's a data point. My daughter is in the eighth week of 7th grade. She
- is in an "honors" math class of about 30 kids. They all know the basic
- concepts of operation, inverse, and identity in general and with specific
- application to the cyclic groups and at least the permutation group on 3
- elements, along with a couple of other examples. They have not yet called
- these a group or in the case of two operation on Z mod n, a ring, but they
- do recognize when they have what the book calls a uni-fold system ( a
- group) and a bi-fold system, ( a ring). I am waiting for the introduction
- of these names. Right now, the book they are in is explicitly titled
- "Intuitive Ideas". It's part of a comprehensive series designed for grades
- 7-10. I don't have the series title or the authors handy, but it was
- developed at Southern Illinois University, at least in part.
