This orchestra unit is complete with pre-test and post-test to show student growth. Included with this unit: intro lesson with pre-test, instructions to 4 complete lessons (one for each orchestral instrument family), review game day instruction, post-test, and group project. It includes worksheets that I have created to go along specifically with the instrument family descriptions that are included in this file. You can make this unit last anywhere from 6-12 weeks depending on how in-depth you go into the orchestra. I may update this product periodically as I see fit.
