Here are a list of music resources I use, as mentioned in my recent youtube video:
Portfolio: To keep everything organized, yet easy to carry. Water proof incase of rain.
Whiteboard: Great for teaching visual lessons such as note names, rhythm, the grand staff, dynamics and steps & skips.
Markers: Colorful double sided markers for more to choose from!
Panda Flashcards: Interval flashcards
Lion Flashcards: Steps and Skips flashcards
Note Flashcards: Play and read all of the notes on the keyboard.
Scale Book: Scales drawn out on a keyboard with fingerings.
These are great references to use when teaching piano to beginners to keep learning fun and engaging.
