Chess teaching resources

Chess coaching can be a hit and miss affair, as most coaches are chess players first and teachers second. So organising a teaching curriculum is not always the highest priority, with coaches usually picking a favourite book or two, or teaching from experience. While this technique often works with children who have already mastered the basics of chess (don't drop pieces, can mate with K+RvK, spot mates in 1 and 2), for children yet to reach that level it is sometimes less effective.
As a result I've always been on the lookout for well structured coaching material. A very battered copy of "Comprehensive Chess Course" has been my main resource for the last 25 years, but finding copies can be a bit difficult. A number of coaching companies have developed their own material, but this is usually 'commercial in confidence' and can't be handed around freely. But chess.com is doing us all a favour by providing free teaching materials, which they are happy to share. You can see the details here, and download a preview. The curriculum is connected with their chesskids.com site, which also provides plenty of material for players and coaches. And if you visit the information page, there is even a direct link to an earlier version of the teaching material, if you want to get an idea about what it covers.
