Voice Threads for Math Journals: An alternative to written communication

I have been playing with the idea of Voice Threads in mathematics especially in the primary grades.  I see them as a great alternative to written math journals which are often difficult for young students who lack sophistication with written communication.  What I like about Voice Threads is that they eliminate the barrier of written communication and allow students to communicate their understanding orally.  As well, others (teacher/students) can respond to the Voice Threads which opens the communication up to collaboration as well.  This would be a great way to support the Mathematical Process of Communication.  Over the next few days I am planning on using this tool to highlight several types of manipulatives and how to use them.  My son who is grade 2 has “volunteered” to help by doing the math and sharing his reflections.  Click here for our first Voice Thread using Cuisenaire Rods.
