Attend To Precision: Circumference and Diameter

This professional development video clip of students engaged in Common Core Practice Standard #6—attend to precision. The video clip shows two important instances of the idea of precision; that precision is important in their measurements of the circumference and diameter and in their use of vocabulary in context as they discover the relationship between circumference, diameter, circles, and pi. Additional resources include a video transcript, teaching tips, and a link to a professional development reflection activity based upon the video.

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.
