Illustrating the Standards for Mathematical Practice

Properties of Quadrilaterals

Problem Solving and Precision, 9-12

Cathy Humphreys facilitates a geometric design task intended to deepen students' understanding of properties of quadrilaterals and scaffold their use of reasoning and proof. Central to the students' exploration of the mathematics is a poster describing an "Investigative Process." The poster is used as a tool by the teacher and students to support problem solving and perseverance.
