Nearly 600 textbooks, 64,000 lessons and more than 3,100 downloadable resources have received Quantile® measures, making it easy for you to find instructional materials that match your students’ math abilities.

The “Find Your Textbook” search tool indicates the difficulty of each lesson in a textbook measured on the Quantile scale and also shows you key concepts — knowledge clusters — of prerequisites and impending skills surrounding the lesson.

Using this information, you can align the measures for lessons with student Quantile measures to differentiate and motivate student learning. Also, by providing insights about the difficulty of the material, Quantile measures help teachers gauge the amount of time with the lesson.
