I hate flashcards BUT my kids love them for some reason. They have them to play with not for 'quizzing' them on. It makes them happy, lol.
Actually DS likes to quiz ME with his flashcards
Fractions themselves I think kids can learn fairly early. How to use the fractions may take more time for the average kid.
Both my kids know/understand basic fractions. DS knows how to add, multiply (somewhat), and can sometimes remember that 2/4 is the same as 1/2. DD only knows if something is 1/2, 1/3, or 1/4 and that the parts must be equal size.
I do find it odd that the flash cards are 8+ unless they get into adding them and other such stuff. Then maybe that's a normal age?
