The Strands in the Mathematics Curriculum

The expectations in the mathematics curriculum are organized into six distinct but related strands: A. Social-Emotional Learning (SEL) Skills in Mathematics and the Mathematical Processes; B. Number; C. Algebra; D. Data; E. Spatial Sense; and F. Financial Literacy.

The program in all grades is designed to ensure that students build a solid foundation in mathematics and develop a positive mathematical identity by connecting and applying mathematical concepts in a variety of ways. To support this process, teachers capitalize on students’ prior knowledge, skills, and experiences; integrate concepts from across the strands; and often apply the mathematics that students are learning to types of situations that might occur outside the classroom.

The following chart shows the flow of the learning through the curriculum and the interrelationships among its various components.

A diagram illustrates the intersecting relationship of social-emotional learning skills and mathematical processes. As described in Strand A, social-emotional skills and mathematical processes are taught in the context of the other five strands.
