Not really sure where to post, so mods please move if appropriate. At any rate, I am helping out with a Horsemanship camp for young children this summer (ages 5-12), and am on the lookout for age-appropriate diagrams/worksheets/coloring sheets of horse anatomy, tack, and even colors. I would love to find something online so I could print it at home, but if you have a recommendation for a must-have book that I could get fairly quickly, I'd be open to that. I know that there are tons of resources online, particularly of horse anatomy, but what I'm really after here is advice on materials to use with children this age. Thoughts?
