You'll find study sheets for the 대교 4학년 curriculum attached. They include the target sentences from the books as well as some sentences from 2008's Step and Jump books (세계로 가는 영어.)
I hope they're not too ridiculously bad and that they're helpful, etc. for those of you on the very first chapters of the book. I'm leaving in a week, so godspeed on your journey through the curriculum!
