This is a must-have resource for teachers in K-4. The book lays out the strategies and order for teaching students their addition and multiplication facts, the rationale for this order, 60 games to use with students, ideas for communicating with parents about the fact families, and various observation tools for gathering data on student progress. The book starts with explaining the 5 fundamentals of Fact Fluency: 1) mastery must focus on fluency, 2) fluency develops in 3 phases, 3) foundational facts must precede derived facts, 4) timed tests do not assess fluency, and 5) students need substantial and enjoyable practice.
