About this worksheet
A 5th grade reading passage explains how muscles grow stronger. It covers the 600 muscles in the body, muscle fibers, micro-tears from hard exercise, rest and sleep, protein, the heart as a muscle and warming up before a game. Nine questions follow, grouped as Retrieve, Infer and Evaluate, with multiple choice, short answers and a true or false table. The sheet ties to Common Core RI.5.1, and the last page is an answer key.
