Definitely supportive....my kids went to a kindy where these were taught from K1. THough they do not understand fully what they all mean, they still can memorize long paragraphs and know the pronounciation (some in PTH and some in Cantonese). At times they have, not intentionally, learned a few words which they recognize when they see them somewhere else! No pushing at all but just 5-10 mins everyday at school and it can be done!
