Here are a few of the Facebook groups I follow:
https://www.facebook.com/groups/SpecialEducationTeachershttps://www.facebook.com/groups/middleschoolmathhttps://www.facebook.com/groups/SpecialEducationTeachersI get a lot of good ideas from these groups that I use in my classroom. It also gives teachers an area to find other resources. The other members in these groups are great and there is a wealth of knowledge if you seek it out.
