Mathcasts 500 Project, K-8
Mathcasts are screencasts, or digital videos of on-screen writing with voice, created by students to focus their thinking on mathematical concepts and problem-solving steps. It was developed by a teacher, Tim Fahlberg. It contains hundreds of elementary and middle school math problems for students to solve using VoiceThread, a free Web 2.0 tool which features annotation and audio tools. Students across the world can now communicate, problem solve, and share math ideas online. This resource could be used to support the Iowa Core Curriculum goal of moving students beyond superficial knowledge to deep conceptual and procedural knowledge through learning for understanding, problem-solving, and inquiry. Teachers and students are encouraged to make their own mathcasts and post these to the Mathcast wiki located at Teachers can choose to set up private VoiceThread accounts for individual classroom use or collaborative learning spaces that can be shared with classrooms around the world.
