Imprecise Geometry with Doug Clements

In this 7-minute video mathematics education professor Doug Clements argues that some of the difficulty young math students have with geometry and measurement stems from classroom materials that are inexact and misleading. He proposes involving children in diverse exploratory activities that foster spatial reasoning and precision of thought about shapes and their properties.

This resource is included in the following PD Collection(s):
CCSS Practice Standard 6Common Core’s Mathematical Practice 6, Attend to Precision, calls for students to be clear in their reasoning, calculation, and communication through the precise use of words, symbols, units of measure, mathematical expressions, and processes. Students recognize various levels of precision and apply them appropriately; they calculate accurately and efficiently. These resources are intended to help teachers and math specialists understand the intent and scope of MP 6 and plan for successful attainment in the classroom. A companion Classroom collection, Implementing CCSS Practice Standard 6, includes resources to help teachers foster this practice with their students.
