This document provides descriptions and examples of what each Mathematics Common Core standard means a Grade Five student will know, understand and be able to do. This "unpacking" of the standards provides instructional guidelines and was developed to assist North Carolina educators teach the Mathematics Common Core (Standard Course of Study).

These five activities give students practice in interpreting and creating network representations that organize information and relate connectedness and other metrics such as time and distance. Among the types of networks studied are transport distances, family trees, events tree diagrams, and factor networks. Teaching suggestions, links to materials, and progress indicators are included.

This interactive Flash activity asks the user to sort shapes into a 2 by 2 chart, known as a Carroll Diagram, based on their properties. Properties used to sort include "quadrilateral" or "not quadrilateral" and "regular polygon" or "not regular polygon."

This library from the classic Annenberg Learner series contains 6 videos (15-20 minutes each) demonstrating how to incorporate the National Council of Teachers of Mathematics (NCTM) standards in grade 5-8 math classrooms. Using minimal technology resources, middle school teachers model effective techniques for guiding and assessing student understanding and offer strategies for keeping students motivated and engaged. Grade 5 videos feature work with equivalent fractions and geometry. The featured techniques also support integration of the CCSS Mathematical Practices. Support pages provide further elaboration and questions to focus viewer reflection and discussion.
