This is a set of flashcards for ALL band instruments' first 5 notes (Concert Bb, C, D, Eb, F). These are full sized (8 1/2" x 11") and are perfect for classroom use. If possible, set your printer to print 2 sided (1 to 2 sided) and use on card stock (plain paper is too thin and the answer shows through). These are great to laminate and use over and over!
The pdf is large since it includes all instruments. However, you can just print off the instruments you need.
