Greek textbooks
Greek is a bit more obscure a subject than Latin but worth having a go at. It seems intimidating but some children really love it, particularly those who have enjoyed studying Latin.
The general consensus seems to be that a child should have studied Latin for a couple of years before tackling Greek and that's the approach we've taken thus far (in fact we've not started it before age 14 yet), but there's no harm trying it earlier depending on a child's interest and aptitude. If you have no knowledge whatsoever of Greek, it is worth leaving it until the child is old enough to teach himself via a book or course (again, this would probably be 14+).
There are many books and online courses available, especially if you want to study, or at least start with, Koine (New testament Greek) rather than Classical Greek (the former is easier as it has a much more limited vocabulary and syntax). These are often aimed at a young age group as they are produced by Christian homeschoolers who want their children to study the scriptures. 'In the beginning' is a free online course which has been recommended to me (and has a very apt name!). I'll be starting that later this year with my (almost) 14 year old and will be able to review it then.
For Classical Greek from scratch I'd recommend either 'An Introduction to Classical Greek' from Galore Park, or 'Greek to GCSE Part 1' by John Taylor (again, as with the Latin, Mr Taylor is very helpful with answers and assistance). The title of the Galore Park book suggests that it is aimed at a more basic level than the Taylor book, and whilst I haven't used the Galore Park book, from the detailed reviews I've read there does not seem to be much difference in terms of levels of complexity. Greek is never going to easy!
Again, there is plenty of material available online to help with studying Classical Greek. There is a course linked directly to the Taylor book on memrise which is effective yet quite 'fun' to do (along the lines of Duolingo). Eton have also put online their own 'Eton Greek Software Project' which is more limited in scope than the memrise course, but very helpful for revision. Quizlet also has plenty of vocabulary tests available.
