This collection of videos allows viewers to observe students as they are learning and to examine their work on a three-part lesson involving emergent multiplication concepts. A grade 2 teacher and her mentor analyze different strategies and models that children use to solve problems as they develop big ideas in mathematics, as well as teaching techniques that foster that development. The resource includes relevant video clips of Doug Clements and Lucy West, a Viewer's Guide, and organizers.

This webpage features a STEM investigation developed by teachers Carrie Lewis and Kelly Steele to strengthen understanding of patterns with grade 5 students. After observing and analyzing dance videos, teams of students create their own routines based on numerical patterns. The page includes a downloadable (pdf) lesson plan, student handouts, and teacher tools, and features a 9-minute video describing the project and demonstrating students at work.

This webpage contains six model lesson plans, videos of the lessons, and accompanying documents (rtf) based on the 21st Century Skills implemented in West Virginia Classrooms. Lessons include: "Survey Data Collection and Representation" (grade 1), "How Can you Tell?" (grade 3),"Coin Toss Experiment" (grade 3), "Alphabetical Probability" (grade 4),"Tree Diagrams" (grades 4/5), and "Is a Sample Ample?" (grade 5). Some of the videos are cataloged separately and listed as a related resource on this page. Each lesson plan includes content, 21st Century, and technology standards with instruction on integrating these three components.
