These materials are from the Early Numeracy in the Primary Grades training series provided by PaTTAN in the past. 

Geary (2013) notes that early struggles in mathematics have consequences that last throughout school completion and affect a person’s overall quality of life, including employment, wages, and healthcare.  Research also indicates that students who struggle early tend to continue to struggle unless schools are able to correct the learning trajectory. These professional development resources supported teachers’ learning and implementation of researched-based instructional practices that build a strong early numeracy foundation for students, thus preventing or correcting issues in mathematics learning.
