I love to put together games and activities for my students. It really helps the learning process and gives all my "hands-on" learners a fun way to learn and reinforce terms, notes, etc. I recently ran across this website and love it! Brainflips allows you (or your students) to create your own music flashcards on-line or use flashcards already created! There a several of them already available for your use.
The nice thing is, they can be viewed in 3 different ways - Introduction Mode - for introducting information, Traditional Mode - where you can see the question and then flip the card for the answer, or Response Mode - where you can manually type in the answer once you see the question. In other words, you can increase the difficulty level.
It's all free and storage isn't a problem since they are all kept on-line for you! Give it a try. Put together your own flashcards and send your students there to try them out.
Love the idea!
