This nonfiction book gives a good overview of swimming, including four basic strokes. equipment and safety. labeled photos accompany the simple text, with bolded words that might be unfamiliar. Those words are then defined in the glossary at the end of the book. Typical nonfiction features (table of contents, index, resource list, text boxes, labels) are present. An additional feature, which makes this book stand out over others is the number of QR codes, which link to extra resources. Once accessed, there are activity pages to print, videos and many other extras that take this book a step above the rest.
