This book educates children about germs. I would use this book with older grades such as third, fourth, and fifth graders. Before, during, and after reading, I would complete a KWL chart about germs with students on the board. As a hook to the lesson, I would get each student to put lotion on their hands (that has glitter in it) and give them three minutes to walk around putting the glitter on the board, knobs, or desks. This would serve as a visual for germs. After reading the book, I would host a whole-group discussion on all of the ways germs get in your body and ways to keep them out. Then we could play a game. To set up for the game, the teacher would need to use painter's tape to make a big circle on the floor or use chalk to make one on the sidewalk. The circle would need to be big enough for each student to jump inside. The students will pretend to be the germs in the story as it is read aloud. The students will begin by standing on the line that creates the circle. As the teacher reads the story aloud, the students will jump in the circle if the germ gets inside the body and will jump out of the circle if the germ is prevented from getting in the body. After playing the game, students could write about how they will prevent the spread of germs in our classroom. This lesson would be good to do during the beginning of the school year or around flu season.
