I teach math to 12 LD students in 7th grade. We use the Steck-Vaughn, Mastering Math series. My kids are quite tired of it. We have been working on money, writing checks and perimeter from an old math book. I read the messages on Saxon series, and have ordered samples of it. Any suggestions? Most of my students (except 3) can multiply and divide with ease. What are some suggestions to work with this group? Thanks
