One year my kids were in PS and I was a teachers' aide. At the end of the year the janitors placed bins in the halls for teachers to purge their "outdated" books and materials. I asked if it was okay for me to take some home. The Principal said "Carry it all home, it's going to be recycled" I had many years of curriculum including flashcards, textbooks, worksheets, notebooks, even colors, pens, rulers.... Maybe you can do it too?
That is really cool. DS came home from school yesterday and had all four of the Language Arts books he had used this past year. His teacher is getting new ones next year. While it is cool she sent them home, not sure what I am going to do with them as he has already used them. I might see if any of the 2nd grade teachers have anything for me. Thanks for the idea!
Regarding your question "maybe you can do it too" - possibly, but I wouldn't want to. It's fun to pick out curriculum, I enjoy catering to their learning styles, I don't care for the textbooks used by our public schools, and I prefer things that aren't geared toward a public school classroom (for sake of ease, lol).
