Book 4 focuses on the Polar Regions -- Arctic and Antarctic. The books are simple enough for a young child to do independently, but a teacher or parent may present the lessons. Each drawing lesson includes a colorful picture and step-by-step instructions, while the writing lesson includes four simple handwritten sentences. The teacher or parent may introduce letter formation or have the children copy the sentences for handwriting practice, or use the lessons as a springboard for creative writing or report writing. Developed by an elementary school teacher and co-authored by her daughter. A brief list of the 21 lessons in the book includes Blue Whale, auroras, Arctic people, polar bear, igloo, tundra, wolf, penguin, krill, scientists.
