 Developing students’ capacity to engage in the mathematical practices specified in the Common Core State Standards will ONLY be accomplished by engaging students in solving challenging mathematical tasks, providing students with tools to support their thinking and reasoning, and orchestrating opportunities for students to talk about mathematics and make their thinking public. It is the combination of these three dimensions of classrooms, working in unison, that develop students habits of mind and promote understanding of mathematics.

 The tasks or activities in which students engage should provide opportunities for them to “figure things out for themselves.” (NCTM, 2009, pg. 11), and to justify and communicate the outcome of their investigation;

 Tools (i.e. language, materials, and symbols) should be available to provide external support for learning. (Hiebert, et al, 1997); and  Productive classroom talk should make students’ thinking and reasoning public so that it can be refined and/or extended. (Chapin, O’Conner, & Anderson, 2009).

 Significant Content (i.e. they have the potential to leave behind important residue)(Hiebert et al, 1997).  High Cognitive Demand (Stein et. al, 1996; Boaler & Staples 2008)  Multiple ways to enter the task and show competence (Lotan, 2003)  Require justification or explanation (Boaler & Staples 2008)  Make connections between different representations (Lesh, Post, & Behr, 1988)  Provide a context for sense making (Van De Walle, Karp, & Bay-Williams, 2013)  Provide opportunities to look for patterns, make conjectures, and form generalizations. (Stylianides, 2008; 2010)

 Students must talk, with one another as well as in response to the teacher. When the teacher talks most, the flow of ideas and knowledge is primarily from teacher to student. When students make public conjectures and reason with others about mathematics, ides, and knowledge are developed collaboratively, revealing mathematics as constructed by human beings within an intellectual community.  NCTM, 1991, p. 34

 No matter where you live-Pennsylvania, California, Virginia, or Canada-students need opportunities to engage in the habits of practice embodied in the Standards for Mathematical Practices in CCSSM  The features of the tasks that you select for students to work on set the parameters for opportunities they have to engage in these practices-high-level tasks are necessary but not sufficient conditions.  The way in which you support students-the questions you ask and the tools you provide-help good tasks live up to their potential.

 According to Webster, RIGOR is strict precision or exactness.  According to mathematicians RIGOR is having theorems that follow from axioms by means of systematic reasoning.  According to most people RIGOR means “too difficult” and “only limited access is possible.”  Also they believe RIGOR is an excuse to avoid high quality math teaching and learning

 Rigor is teaching and learning that is active, deep, and engaging. ACTIVE DEEP ENGAGING

 Active learning involves conversation and hands-on/minds-on activities. For example, questioning and discovery learning goes on. ACTIVE DEEP ENGAGING

 Deep learning is focused, attention given to details and explanations, via problem solving or projects. Students concentrate on the intricacies of a skill, concept, or activity. ACTIVE DEEP ENGAGING

 When learning is engaging, students make a real connection with the content. There is a feeling that, although learning may be challenging, it is satisfying. ACTIVE DEEP ENGAGING

 Rigor is a process—not a problem ACTIVE DEEP ENGAGING

USING THE NCTM PRACTICE STANDARDS AND THE CCSSM HOW DO WE GET STUDENTS ACTIVE AND ENGAGED, THINKING DEEPLY ABOUT MATH?

Overwhelming evidence suggests that we have greatly underestimated human ability by holding expectations that are too low for too many children, and by holding differential expectations where such differentiation is not necessary.

 Say “Hi” to everyone at your table and shake hands.  How many handshakes were exchanged at your table?  If we exchange handshakes for the entire room, how many handshakes would there be?
