    Professional Development at Schools or Districts

    Teachers in classroom doing math professional development


    If your school or district is looking for math professional development, we offer a variety of services that will increase student achievement and lead to improvement in student and teacher perceptions of mathematics. Explore our offerings, and contact us (see below) to discuss how we can help you. The best option is a combination of services. According to the Institute of Education Sciences (PDF), effective professional development displays three primary characteristics:

    - It's sustained over time
    - It’s collaborative
    - It allows teachers to practice concepts.

    That’s why we offer professional development through various opportunities. We want to ensure that our collaboration and partnerships are effective.

    • Teacher and Leadership Development
      • ​Teacher Development. We collaborate with you to offer personalized workshops for teachers, paraprofessionals, and those who have direct impact on student learning. We customize these workshops to meet the your needs.
      • Leadership Development. As educators improve their practice, it’s also critical that leaders do, too. We offer workshops for leadership teams to analyze their practice, deepen their mathematical content knowledge, and understand what to look for when evaluating mathematics teaching and learning.

      Select an option from this list or request something new. Either way, we’ll tailor the experience to your needs.

      • Aligning Curriculum with Content Standards
      • Deepening Understanding of the Standards for Mathematical Practice
      • Differentiating Math Instruction to Meet All Needs
      • Enhancing Instructional Routines
      • Exploring Number Talks and Other Activators
      • Incorporating Formative Assessment Strategies
      • Incorporating Mathematical Discourse in the Classroom
      • Integrating Accommodations and Modifications to Reach All Learners
      • And more....
    • Mathematics Content Coaching

      It’s nice to hear the “in theory” advice, but we all know that classrooms are complex spaces where one small shift can have a large effect on whether students leave class with confidence and understanding. To help, we come into your classroom to offer high-quality content coaching with the goal of improving the teaching and learning of mathematics.

      In this model, we start by pre-conferencing through planning a lesson with a teacher or group of teachers, followed by co-teaching that very lesson. We then do a post-conference to debrief and cultivate ideas for how we can collectively improve our work.

    • Family and Community Workshops

      We help families understand how and why the way we teach math today is different from the way most adults learned. In addition to providing our own workshops, we also help schools and districts develop their own family math nights and information sessions.

      If you're looking for more information on engaging families, our center director has co-written Adding Parents to the Equation and an accompanying free book to provide families support. She is able to work with your district to run book studies, workshops, webinars, or other engagements to ensure your families can communicate mathematically with their children.

    • Assessment of Curricular Alignment or Systemic Structures

      We help with research and resources for selection, implementation, and alignment of curriculum. Whether you’re struggling to implement your current curriculum or looking to pick a new one, we can provide assistance. If teachers are developing their own materials, our center’s assistant director, as the author of Nix the Tricks, is uniquely poised to ensure the strategies support understanding.
