The new Pacon® Dual Ruled Composition Books feature two alternating ruling styles. The right-hand page offers a 3/8" wide ruling for traditional note taking and the left-hand page features a 1/4" grid ruling to draw coordinating graphs, illustrations and interpretations. Note taking in this manner engages both hemispheres of the brain. These durable, hard cover, one-subject books are available with Yellow colored covers and coordinating Light Yellow colored paper on the inside. Using colored paper has been shown to help students with dyslexia work through the impacts of this learning disability. The colors also allow students to organize by class, theme or semester. Recyclable.
