Innovative lessons for key K-8 math concepts and skills

Adopted in 2015, the four broad strands (Number, Algebra, Geometry, and Data) are the same as earlier standards while Grades K-5 have an even stronger focus on building a solid foundation of number sense. DreamBox builds strong number sense, makes it easy to track progress toward Nebraska’s College and Career Ready Standards for Mathematics and to create personalized assignments aligned with specific Nebraska standards from the Insight Dashboard.
