The How, When & Why of Physical & Digital Manipulatives with Natalie Crist & Patrick Vennebush
The How, When & Why of Physical & Digital Manipulatives with Natalie Crist & Patrick Vennebush ROUNDING UP: SEASON 5 | EPISODE 4 Recently, there's been a great deal of debate around the role digital manipulatives should play in an elementary math classroom. In this episode, we'll talk with Patrick Vennebush and Natalie Crist about the role physical and digital manipulatives can play in a classroom. We'll try to clarify the opportunities, the limitations, and the questions teachers should ask themselves when they consider using these powerful tools. BIOGRAPHIES Patrick Vennebush is the chief learning officer at The Math Learning Center, where he manages the development curriculum products and professional learning services, including the newly released Math MultiApp by MLC. Natalie Crist is the director of content development at The Math Learning Center, where she leads the development of curriculum products, including Bridges in Mathematics. In addition to her work for MLC, Natalie is an adjunct faculty member at Towson University and McDaniel College.

See It! Say It! Symbolize It! with Dr. Patrick Sullivan
See It! Say It! Symbolize It! with Dr. Patrick Sullivan ROUNDING UP: SEASON 5 | EPISODE 3 Representations, language, and symbols are all important ingredients in building students' conceptual understanding and fluency. But how can we understand the relationship between those three ingredients? And what happens if we leave any one of them out of the recipe? In this episode, we explore these questions with Dr. Patrick Sullivan, professor of mathematics at Missouri State University. BIOGRAPHY Dr. Patrick Sullivan teaches mathematics content and methods courses for future K–12 teachers at Missouri State University. His work focuses on helping teachers unleash children's mathematical brilliance, particularly in the areas of number, fractions, multiplication, and mathematical reasoning. He has published in the areas of elementary mathematics education, mathematical authority, technology-supported learning, and statistics education. Dr. Sullivan is the author of See It, Say It, Symbolize It (Solution Tree), which challenges educators to rethink how mathematics is taught and learned. He is also the past president of the Missouri Council of Teachers of Mathematics and the founder and director of the Young Mathematics Teacher Academy, a program designed to encourage and mentor high school students interested in becoming mathematics teachers. Formerly, he served as a school leader and high school mathematics department chair. He has received the Presidential Award for Excellence in Mathematics and Science Teaching and the Missouri Teacher Educator of the Year Award.

Organizing Board Space to Support Reasoning & Connection, Part 2, with Dr. Tutita Casa & Katherine Mack
Organizing Board Space to Support Reasoning & Connection, Part 2, with Dr. Tutita Casa & Katherine Mack ROUNDING UP: SEASON 5 | EPISODE 2 Repositioning the classroom board as a shared space for teachers and students can create opportunities for deeper student learning and have a subtle but significant impact on students' math identities. In part 2 of this two-part series, Mike talks with Tutita Casa and Katherine Mack from the University of Connecticut about ways teachers can use the board to reflect student reasoning, draw attention to key ideas, and close a lesson without funneling students to a correct answer. BIOGRAPHIES Tutita Casa is an associate professor of elementary mathematics education at the Neag School of Education at the University of Connecticut. Her work is aimed at supporting teachers to empower students to grapple with the mathematics and engage with the discipline in ways similar to how mathematicians go about their work. Katherine Mack is a doctoral student in curriculum and instruction at the University of Connecticut. She examines how elementary teachers can facilitate mathematical discourse by repositioning the instructional board as a space that centers student reasoning and makes it visible.

Organizing Board Space to Support Reasoning & Connection, Part 1, with Dr. Tutita Casa & Katherine Mack ROUNDING UP: SEASON 5 | EPISODE 1 Classroom boards have traditionally been a space that belongs to the teacher, even as technology changes. What would it look like to rethink our relationship with the board, repositioning it as a shared space for teachers and students alike? In part 1 of this two-part series, Mike sits down with Dr. Tutita Casa and Katherine Mack from the University of Connecticut to talk about ways teachers can establish norms and develop practices that make the board a shared space that reflects students' reasoning.

Looking Ahead to Season 5
Looking Ahead to Season 5 Rounding Up returns next week for its fifth season, examining even more ideas, concepts, and practices that shape teaching and learning in elementary mathematics classrooms. This season, we invite our listeners to engage with us by leaving a comment on our website, mathlearningcenter.org/podcast. We look forward to hearing from you! TRANSCRIPT Mike Wallus: Rounding Up returns for Season 5 next Thursday, September 3rd, with brand-new episodes. We'll examine ideas, concepts, and practices that shape teaching and learning in elementary mathematics classrooms. I'm your host, Mike Wallus, the vice president of educator support at The Math Learning Center, the organization behind the Bridges in Mathematics curriculum for early childhood learners all the way through fifth grade. This season, we'll chat with experts in classroom infrastructure— Tutita Casa: We're trying to take those unspoken norms that the board is a space that traditionally is led by the teacher, commanded by the teacher, too often didactically, and how can we open up that space to reflect what our students are thinking? Mike: Content— Patrick Sullivan: I felt like my teaching improved exponentially when I just started listening to my students. And I'm like, "Oh, they don't really understand that the way I thought they would." And OK, so now I can modify and I can latch on to what they're telling me as opposed to just me thinking, "Oh, this is what's going to be best." Mike: Math identity and classroom culture— Fawnda Norman: Math is about making connections and communicating with each other. It's not just about solving the problem and getting the right answer. And so, if we can get students to communicate with each other, they're gonna learn that they are all mathematicians and we can all do this. Mike: Identifying critical moments in the classroom— Jamila Riser: Where's this moment in the lesson where the students have potentially the greatest, most visible opportunities to make the key connections that they had identified in the lesson to reach that goal? Mike: And a whole lot more.
