My Take
LOVE, LOVE, LOVE this website. The songs are bumping (I teach in Brooklyn and if my kids like the raps they gotta be good) and the kids remember them! You can use this as a quick lesson in the mornings or as a period long lesson. The kids remember the info and are able to apply it to the daily classwork or homework.
How I Use It
I use the songs as a quick lesson in the mornings during homeroom. I use one song a week and then review them every now and then to refresh their memories. It worked well, this year I would like to add student access to help them build more understanding.
