Hi-Lo Chapter Books for Children. This series of short novels was designed to engage a broad spectrum of struggling readers. No longer will upper-elementary students have to read material junior to their maturity and interests. Characters are age appropriate and come from diverse cultures and backgrounds. Science fiction, sports, paranormal, realistic life, historical fiction, and fantasy are just a few of the many genres. Books are no higher than a 1.5 reading level, with illustrations on every spread that support visual literacy and draw kids into the text. Tommy loves MMA. He and his friend Ben are the best at Stars MMA Fight School. They both compete to represent the fight school at a MMA competition in the city. As usual, Tommy chokes. Ben is the winner, even though Tommy is the better fighter. But Ben breaks his leg, and Tommy has to learn to tune out and focus to win.
