How are math facts mastered? Which methods promote automaticity across a broad range of students? What if we could solve the problem of math fact fluency in just 10 minutes a day? Come find out the answers to these questions. Learn how to optimize classroom instruction and practice through empirically-validated methods that are effective, efficient, and fun. The presenter will discuss the sophisticated interactive online system used by these students to learn new facts, which enables large-scale data tracking within interactive content via methods originally developed under National Science Foundation grants. Based on this data, the presenter will describe how to move students to full fluency, with particular emphasis on basic principles that are efficient as well as effective. The session will be of interest to any educator with an interest in math fact fluency and empirically-verified methods for its development.
