There are many ways to teach digraphs. My favorite way introduces digraphs with hand motions. Teaching with multiple modalities ensures you reach more students. When I introduce the “H Brothers” I use the story and motions from the Project Read program. Each brother has a story to help students remember the motions. The “CH brother” is the brother who likes choo-choo trains so students makes a motion with their arms like train wheels while saying “ch, ch, ch”.
