The document summarizes a math assessment and program called KENS Math. It provides tools to assess students' number sense skills, monitor their progress, and support individualized instruction through leveled learning. The assessment helps teachers identify starting levels for students and which need extra practice. It also facilitates response to intervention. The program provides lesson plans, manipulatives, and materials to support the three core number sense skills across 12 levels. Research found errors on the assessment predicted later math difficulties and progress monitoring is a key part of the program.
