This I have/who has set includes 29 cards. I can make more upon request. Included are instructions and an answer key which states the instrument name and the family the instrument belongs to. This could be an easy game for a substitute. This could also be used for review and/or assessment of the instruments of the orchestra.
This product would work well with my instrument family portfolios, found here: http://www.teacherspayteachers.com/Product/Instruments-of-the-Orchestra-Student-Portfolio-1045904
