I'm a secondary teacher stuck in a rut - seem to end up spending all my time trying (and largely failing) to get KS3 kids to play in time with each other, either playing or composing something on the keyboard, and them performing at the end of the lesson. I need inspiring ideas to engage them more, while not being anything too outlandish as behaviour can often be tricky. What's the lesson activity that works best for you, that you are most proud of and gets the kids learning and having fun? I only have keyboards (and voices) as resources, and those can be unreliable sometimes too... I just feel I have gone stale and I'd love some new ideas!
