As a 18 year veteran of homeschooling, I was appalled when a listing for a Teacher's edition I was selling was removed as Ebay feels that "school children will use a teacher's guide to cheat". It only goes to show what's wrong with the education system. A student cannot just show an answer to a math problem, they need to know the process. Anyway...to all of you that have Teacher's Editions I would suggest listing them on homeschoolbid.com as I did. (I'm hoping THIS will be a possitive experience) as I must say I'm rather dismayed with EBAY!
