I've been toying with this idea for a number of years, before giving away a free version 2 years ago. This has now developed into a 75 page full colour book. The plectrum grades make learning the guitar fun and rewarding, particularly for primary school students and now there is a companion piece for lessons!
There are over 40 songs / excerpts of songs and a steady progression of riffs, chords, tricks and techniques along the way. Please find the link in the up strum's page if you're interested in buying a copy .
Thanks!!
