Think Tank #4: Developing Additive Reasoning Using the Bead String Model

In Think Tank #4, we will explore the power of the bead string APP, which has been newly redesigned. In this one-day PD, teachers will gain access to the new bead string APP. They will also be given sets of lesson write-ups they can use in their classrooms to develop students’ reasoning in early number, addition, and subtraction.

Following this PD, teachers can sign up for a series of monthly one-hour webinars that are designed to support their on-going learning with the bead string model.
