The Case of Ibby

Videos of a 3rd grade student beginning to make sense of multiplication set the stage and support our thinking as we analyze the instructional settings used and decisions made by the teacher to support the conceptual development of multiplication. We will consider the phases of instruction as laid out by Dr. Bob Wright in Developing Number Knowledge and The Learning Framework in Number. We will unpack the instructional moves of distancing the setting, using color and screening to support mental strategies in multiplication conceptual development and a research based instructional trajectory.

You will leave the session with new ideas about how children come to understand multiplication and ways to support children's learning.

Thank you for your interest in the session! You will be able to watch the sessions as many times as you want through March 8, 2022. After that, the sessions all go inside the Build Math Minds PD site for members to have access to at any time. A download of the handouts for this session is available after filling out the link below to win a copy of Developing Number Knowledge.
