I teach 6th grade math in Massachusetts. I'm looking for recommendations for:
1) excellent middle school math resources: websites, apps, books, lessons, etc; and
2) other great online math groups like this one where I can benefit from others' work.
So far, my challenge has been finding too many online recommendations that require hours of sifting through. Ideally, I'd like to get recommendations for what are regarded the best of the best. Something akin to Jane Hart's "Top 100 Tools for Learning," which provides a list of the most highly regarded learning tools.
Thanks for your help.
