Hi Sharon -- I have all of those books and find them very useful for getting
me started with a new subject or new age group. I don't use the slides much
because our room doesn't really accomodate slides -- too bright, even with
shades down. I buy reproductions from Art Prints and we keep a file on
various periods, themes, etc. We use any visuals we can find, attach them to
chalkboard with magnetic clips and then allow the students to look at them
more closely after meeting.
