For those of you who homeschool I have an awesome resource that might interest you. It is a site call Classics for Kids. This is what they say. "This site is designed to help you introduce your child to classical music. Music not only has the power to stimulate the mind, enrich the heart and soothe the soul; it can help children to think more creatively, develop craftsmanship and discipline and learn the value of excellence."
One thing I love about this site is that they feature one composer each month and each week they have different actives based around that composer. They have radio shows that you can listen to and lots of different kinds of actives to help kids be excited about the classics including games, learning about the instruments of the orchestra, musical dictionary, audio of Classics for Kids programs, and collections for music from periods in music history.
They have sections for parents and teachers along with lesson plans, activity sheets, and they list lots of additional resources that are available to you to help teach your kids about classical music. They have made it so easy and no previous knowledge is needed. Check this site out and tell me what your favorite part is.
