Hi,
I am from the UK. I homeschool my son aged 8. I use mostly American materials because I really like TWTM approach and I haven't been too impressed with materials from UK. We use:
FLL, WWE (will probably move on to CW)
Story of the World (I use a lot of Usborne books)
Artistic Pursuits
Singapore maths (with MM for additional practice). I think SM is a fantastic program.
I haven't quite committed to a science program. We are studying Astronomy at the moment using a combination of Apologia and Elemental Science. I also throw in a bit of Singapore Science(MPH).
Lastly I use the Memoria Press series for Latin. We are doing Latina Christiana at the moment but I am in a real dilemma about the teaching declension of nouns. I do not know whether to just go with the American approach or amend the materials in line with the English approach.
I haven't had a problem with the other materials. In fact discussing the variations in spelling between America and England seems to be a good memory aid.
I hadn't heard of Galore Park but I've had a chance to look through the materials and they look good.
