This workbook series, Flashbook Kids, is for grades K-8 and covers math, reading, spelling, language arts and testprep. The books can be purchased individually or they also have all of the subjects for each grade in one book. The lessons are clear, offers great review within the program, interesting pictures and great explanations. I have used a variety of subjects in a couple of different grades and I highly recommend this program for working with your child afterschool (afterschooling), for homeschooling all or individual subjects or summer review.
Barnes and Nobles carry the books but if you want you can purchase some of them through Amazon.com you can also find some of the books at Booksamillion.com
