Popular Music Performance Packs
Resource packs with lyrics, chord sheets, and accompaniment figures. The resources have their relevant piano, guitar (and in some cases) ukulele chord diagrams. Some have rhythmic details and other figures.
I've had great success with these with Year 9 classes, as they can approach the sheets at a level appropriate to them, whilst it also allows the more able opportunity to stretch themselves and transcribe patterns from the original song, as it provides them a framework to make an educated guess on the how the parts go.
