I am constantly looking for new ideas on how to integrate technology in the elementary music classroom. Webquests, iconic animation of music, historical web sites, worksheets, etc. Would love to share what I have.
SmartMusic interactive computer-based music practice software could be cool. I also think that if you have GarageBand, it's really a cool tool for kids to make their own music, picking up the composition piece to their education. I'm not sure what PCs have for that option.
I am a kindergarten music teacher that loves to use technology in the classroom. I am very lucky to have access to a portable SmartBoard at both schools I teach in as well as have an iPad, which is used not only for keeping my music in one place but for the music apps that help my kindergarten students. The iPad can be projected onto a white board or wall so all students can see the App screen. I love using the Apps that are free from the App store.
I also use SmartBoard presentations in my classroom some that I created as well as some that are borrowed from the SmartBoard website where teachers add lessons they created to share.
I love using Groovy Music (software) that can be purchased. This software is perfect for elementary kids and supports music learning and creation. If you have the money to buy it the software is well worth the money.
