Today's math teachers have a lot to balance. From following the Standards for Mathematical Practice, to incorporating real-life application into math problems, to finding resources that are flexible enough to meet a range of students' needs.
Cathy Fosnot's Contexts for Learning Mathematics is a rigorous K-6 classroom resource that uses a workshop environment to bring the Standards for Mathematical Practice to life. Rich, authentic contexts provide a backdrop for fostering the use of mathematical models as thinking tools, tenacious problem solving, and the reading and writing of mathematical arguments and justifications to ensure the development of a positive growth mindset.
In the following video, Cathy Fosnot describes how modeling the problem in a way that provides applicable context to the children's own life is critical to helping them understand mathematical concepts.
