Summer is a great time to catch up on some of that good literature that we just never seem to get around to during the regular academic year. So here are some links to books recommended to middle school, mostly by some different school systems:
The Kinkaid School Middle School Summer Reading Lists 2011
Houston Area Independent Schools Library Network Recommended Reading Lists 2011
2011 Parkway Summer Reading List for Students Entering Grades 6-9
I'm sure that there are others, but here are some to get you started.
Even if we don't read any of these books, I like to get an idea of what different school are advising for their middle school students. Another way I use these lists is to pick up suggestions of historical fiction for the time period we will be studying in the coming academic year (in our case, 20th century history). I like to have my son read at least one historical fiction of the time period, and this is a good way to find one that some other educators have found to be appropriate.
