Teachers can use this interactive tool to help students build a conceptual understanding of subtracting fractions with common denominators by linking visual models to procedures. The page includes a video demonstration of the tool. Free registration is required to use the tool. A paid subscription is necessary to access curriculum materials and allow full student use. | Demonstration, Interactive Media, Video Grade Level: 4, 5, 6+ | |

These videos focus on specific standards and include examples/illustrations geared to clarify the meaning of the individual standard rather than to be a guide on how to teach it. There is an introductory video for the collection; the videos are organized by grade level and can be downloaded as well as viewed online. | Instructional Strategy, Reference Materials, Video Grade Level: K, 1, 2, 3, 4, 5 | |

This lesson activity from NCTM's Mathematics Teaching in the Middle School presents a fraction activity in which comparing fractions is explored through the use of sharing chocolate bars. In the lesson students present their reasoning, keep a table, and discover patterns. The PDF lesson/article contains many variations for challenge and extension. | Activity, Reference Materials, Article Grade Level: 4, 5, 6+ | |

This 88-page document addresses the meaning of the Common Core State Standards for teaching fractions in grades 3-7. For each grade level the specific standards that are addressed are listed, followed by a detailed explanation of what the standards mean, including visual models, and any misconceptions teachers or students might have about how specific standards apply to fractions in the CCSS. | Instructional Strategy, Reference Materials, Article Grade Level: 3, 4, 5, 6+ | |

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. | Demonstration, Instructional Strategy, Video Grade Level: 5, 6+ | |

In this 7-minute video Dr. David C. Geary describes how to build students' understanding of the concepts behind the operations with fractions. He identifies the reasoning behind several student misconceptions and urges teachers to use these misconceptions to build conceptual understanding. A transcript of the video is available in PDF format. | Video Grade Level: 4, 5 | |

This collection of 21 videos (2 - 12 min each) details the 3-part lesson structure used in Ontario math classrooms. Lessons involve open-ended problems and teaching practices that build self-efficacy, independence, collaboration, and communication. The videos follow a team of teachers and support staff as they plan and co-teach a lesson on fractions based on the 3-part structure: activation of prior knowledge, work on the problem, and consolidation and practice. The series includes clips offering related perspectives from Lucy West, Deborah Ball, Marian Small, and Steven Katz. Videos may be streamed or downloaded (.mov or .wmv). A downloadable (pdf) Viewer's Guide summarizes and elaborates on the videos and provides reflection questions. | Instructional Strategy, Lesson Plans, Video Grade Level: 4, 5, 6+ | |

This iOS app gives students an opportunity to visually model and calculate six different types of fraction applications, all in the context of solving word problems. Types of problems include finding a fraction of a number, using a known part to find the whole or another part, and problems using the four operations. Teachers can track a student's progress throughout the problem sets. An online version of this application is cataloged separately as a related resource. | Interactive Media, Mobile App, Problem Set, Video Grade Level: 4, 5, 6+ | |

Teachers can use this interactive tool to help students build a conceptual understanding of fractions by creating artwork on a grid, where each color represents a fraction. Students learn how fractions are related to each other and that their value is determined by the value of the unit.
