A colleague of mine and I are teaching general music to grades 6-8. We are a ‘Core Knowledge’ school (not to be confused with Common Core!!) and are having difficulty finding a decent textbook to teach the curriculum topics in Core Knowledge over the course of an entire school year. We have some materials but there are so few topics in Core Knowledge for each grade level we have trouble filling up a whole school year! Any good middle school general music resources you can share would be helpful. We teach in a charter school, and I would say our students are high achievers academically, so more advanced readings wouldn’t be a deterrent. We also teach based on a Classical Education system, meaning we use original source material and move from rote memorization in the younger grades to more deep-thinking techniques in the higher grades. Thank you in advance for your help!
