Specially designed units and investigations created by the Math in the City team enhance our core mathematics curriculum, as we adopt select units in the Contexts for Learning Mathematics (CFLM) Series. Each grade’s yearly curriculum builds in opportunities to engage with these rigorous and super engaging supplemental units that allow our mathematics workshop environments to come alive! As described by the CFLM team, “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.” These open investigations “allow children to engage in mathematizing in a variety of ways,” recognizing that mathematical growth is achieved progressively and comes to each learner uniquely.
When you walk into a mathematics classroom engaged in one of these multi-day journeys, whether a 2nd grade class measuring for an upcoming art show or a 4th grade class exploring fractions through sub sandwiches shared on a field trip, students are doing a lot of the following - talking, listening writing, drawing, and revising their thinking as our contexts evolve. The Mathematical Practice Standards, again, are nurtured strongly in these supplemental adventures.
