While I love the Read 180 program, it is very structured and sometimes I like to deviate a bit and I KNOW the kids like to also. I found a site I use on Fridays for The Week in Rap. It is from Flocabulary and has cool rap videos for lots of language arts, social studies, math and other academic subjects. You can sign up for a free trial and then pay $7 a month for only the months you want. I think it's worth it. To me, helping kids, and myself, stay abreast of current events is very important.
