My firsties take home either a decodable reader or basal reading book every day except Friday. I send these home in a "Book Buddy Bag" (plastic bag with handles) labeled with the child's name. Inside the bag is the sheet that corresponds to what book he/she is taking home. The story they are to read should be "highlighted". Child reads to "someone", has the paper signed and returns both paper and book the following day (inside the bag). The bag protects the books and most of the time will last the whole year.
Each Reading Level has 2 sheets - Decodables, Basal
I run them off on different colors - helps me to keep them straight!
