[This] systematic, theory-based, and empirically tested program will help to improve the quantitative competencies of young children who would otherwise be disadvantaged throughout their schooling. --David C. Geary, Ph.D. University of Missouri (07/15/2013) An absolute MUST resource book . . . A wonderful collection of 24 evidence-based interventions to build children's competencies with numbers. --Jane M. Wilburne Associate Professor of Mathematics Education, Penn State Harrisburg (07/15/2013) Clear and are easy to administer, even for a novice teacher. The intervention strategies are well-grounded in research and practice, and the activities are engaging. --Sally Moomaw, Ed.D. Assistant Professor, Early Childhood Education, University of Cincinnati (07/18/2013) A systematic, digit-by-digit introduction to numbers--which, once mastered, should provide a firm foundation for all elementary mathematics. --Nancy Krasa, Ph.D. co-author, Number Sense and Number Nonsense: Understanding the Challenges of Learning Math (08/05/2013) A first-rate, comprehensive, and evidence-based suite of number sense interventions that--if implemented as per the guidelines--will surely yield noticeable improvements in young children's knowledge of and proficiency with numbers, number relations, and number operations. --Daniel B. Berch, Ph.D. University of Virginia (08/05/2013) This is the kind of intervention support that teachers need to effectively address the needs of students with mathematics learning difficulties. It is a welcome addition to educators providing intensive multi-tiered mathematics instruction. --David Allsopp, Ph.D. Professor, Department of Special Education, University of South Florida (08/05/2013) Provides a solid foundation for developing a rich understanding of mathematics. Rigorous research conducted on Number Sense Interventions shows the promise of the program for positively impacting student mathematics achievement. --Ben Clarke, Ph.D. Research Associate, Center on Teaching and Learning, University of Oregon (08/13/2013) a Clear and are easy to administer, even for a novice teacher. The intervention strategies are well-grounded in research and practice, and the activities are engaging.a --Sally Moomaw, Ed.D.
