Each book is assigned a color coded level. Level 1 (preK-1st grade) is for beginning readers. Level 2 (1st-3rd grade) is reading with help. Level 3 (2nd-4th grade) is for reading alone. Level 4 and the chapter books are for 3rd grade+, and are for advanced readers. These readers contain actual stories that children will enjoy, rather than simple words strung together. They are books that children can, as they claim, read, and that they will read over and over.
Skol is a Scandinavian greeting similar to cheers that means good health. The term is often used to toast or salute a person. The term is commonly used in Norway, Sweden, and Denmark when drinking to good health. It appears as skÃ¥l in Norwegian, Swedish, and Danish.
SKU (stockkeeping unit, sometimes spelled Sku) is an identification, usually alphanumeric, of a particular product that allows it to be tracked for inventory purposes. Typically, an SKU (pronounced with the individual letters or as SKYEW) is associated with any purchasable item in a store or catalog. For example, a woman's blouse of a particular style and size might have an SKU of 3726-8, meaning Style 3726, size 8. The SKU identification for a product may or may not be made visible to a customer. SKU numbers can sometimes be seen in online e-commerce sites.
