The main design principles in the New York State Common Core Learning Standards (CCLS) for Mathematics standards are focus, coherence, and rigor. These principles require that, at each grade level, students and teachers focus their time and energy on fewer topics, in order to form deeper understandings, gain greater skill and fluency, and more robustly apply what is learned.
Focus in the curriculum is meant to give students an opportunity to understand concepts and practice with them in order to reach a deep and fluent understanding.
Coherence in the curriculum means progressions that span grade levels to build students’ understanding of ever more sophisticated mathematical concepts and applications.
Rigor means a combination of fluency exercises, chains of reasoning, abstract activities, and contextual activities throughout the module.
