A parent recently turned me onto this fantastic teaching tool. Pipe cleaners are economical, colorful, hands-on, quiet and clean up with the swoop of one hand. What's not to love? We have been using these to study the shapes of musical symbols. The hands-on quality makes it a slow and individualized learning tool for young children to study the details of the shapes in musical symbols.
We have also used pipe cleaners to re-create Blue Jello cards with great success (see picture below.). For more information on the incredible Blue Jello cards that are a part of the highly recommended Music Minds Games curriculum please visit: http://www.musicmindgames.com
