    Reasoning and Sense Making in the Mathematics Classroom

    March 22 | 7:00 p.m. ET


    Developing students' capabilities with reasoning and sense making processes should be the primary goal of mathematics instruction. In order to achieve this goal, all math classes should provide ongoing opportunities for students to productively use these processes. In this webinar, Michael Battitsta will illustrate the nature of mathematical reasoning and sense making in prekindergarten–grade 8 by showing examples from a three-book series on Reasoning and Sense Making in the Mathematics Classroom. With student and classroom vignettes as well as instructional tasks, learn how instruction can support students in their development of reasoning and sense making.

    The Friday Institute at NC State, has two exciting professional learning opportunities that may be of interest to mathematics teachers and other educators in your state. In the Place @ the Friday Institute, you will find MOOCs (Massive Open Online Courses) designed for educators. The Teaching Mathematics with Technology and Teaching Statistics Through Data Investigations MOOCs are completely FREE professional learning opportunities that are designed to develop the pedagogy and content understanding for teachers in middle school, high school, and at postsecondary levels. The courses are built by expert teacher educators in their field and on research-based models of effective professional development, professional learning communities, and online communities of practice.


    Registration for both courses is now open and will launch on September 26, 2016.


    At the end of each course, participants can request a certificate of completion. In some states, such as North Carolina, teachers are also eligible to receive renewal credits, Continuing Education Units (CEUs). Teachers will need to contact their local state agencies to inquire about the eligibility in their states. It may also be a great opportunity for teachers to work in teams or PLCs to complete the course together.


    If you think either of the MOOCs described below are a good fit for educators in your state, please share this information with them. We would be happy to provide any other materials you may need (e.g., logos, course descriptions, course objectives, etc.) in order to disseminate information about the courses as widely as possible to District/LEA and teacher networks. Let us know if you have any questions, and thank you!


    Below is a brief description of each MOOC:

    Teaching Mathematics with Technology

    Many recognize that technology can be an invaluable tool to support students’ engagement in and learning of mathematics. The Teaching Mathematics with Technology MOOC is designed to equip teachers with instructional practices that leverage technology to support students’ mathematical learning. Participants will learn how to use technology to enhance teaching and learning, analyze student thinking, and engage students in productive discourse. Here is a link to the course


    A short promotional video can be viewed here:


    Teaching Statistics Through Data Investigations

    The Teaching Statistics through Data Investigations MOOC is designed primarily for educators who teach statistics, in grades 6-12 and in post-secondary contexts, but is relevant for those who teach disciplines that use data-based explorations extensively to make claims and inferences. This course allows participants to learn, along with colleagues from other schools and districts, to use an investigation cycle to teach statistics and to help students explore data to make evidence-based claims. Here is a link to the MOOC:
