Dyslexics tend to be visual thinkers. As they read or hear, they want to visualize what they're learning. Take this sentence: "Give me the ball." A young dyslexic may get stuck on the words "give" and "the". The dyslexic student can visualize a ball but has a more difficult time visualizing "the". Ron Davis uses clay as a method to help dyslexics visualize non-visual words. His students work on mastering certain known-troublesome words with clay. Here Davis shows how a student illustrated a boy connected to a ball to visualize "the".  The struggle is to always visualize, which takes more energy and causes dyslexic students to take longer to complete a task.
