I've taught N the different type of occupations and the corresponding words using flashcard method many months back. Its been a long time since we last saw these cards. So i decided to take them out (there are about 15 of them) today and help N revise. To my surprise, he didn't need any. He remembered all of them without any help from me (except one).
How did i know? I layed down all the word cards on the floor and handed him one picture card at a time. He effortlessly and swiftly placed the picture cards right where the respective words are. Well done my boy!
