If your child has weak foundation aka cannot read or recognise most chinese words in the textbook, then NOW is the best time to help them up their results for CHinese in 6 months time.
Step 1: study the textbook texts and read ONE sentence aloud daily and study 3-5 words (识写字、识读字) daily. write down all the words learnt in a notebook everyday. (parents can check notebook weekly).
Do the above daily for at least 3 months. every day 30 minutes.
Step 2 study the words again and construct a sentence per word on your notebook (Do 3-5 sentences a day)
read textbook and check with teacher the pronounication (email/sms audio) and rectify any mistake that day. rerecord and listen to the correct ones.
continue until you can read the whole text without stops and all pronunciation is right.
This may take at least 2 months of hard work.
I can assure you before step 2 Ended most of you would have given up or on the way to giving up, SO you need to be determined and have a strong will to survive till now, congrats to you for now.
