Workshop Dates: October 6-7, 2017

Grades: 6-12

Known for: Estimation 180, 3-Act tasks, clothesline activities

In this interactive, collaborative, and engaging workshop, we will focus on Number Sense, Student Thinking, and Problem-Solving. We’ll explore readymade tools and resources that support diverse student populations through purposeful mathematical learning. Learn how to implement number sense activities that students need and are connected to the grade level content you teach. We will better understand why and how students need to be active members of a mathematical discourse community by using student thinking to drive our math instruction and by using problem-solving to push student potential and deepen conceptual understanding of mathematics.
