Learning different skills may require various strategies, but every day practice is the foundation. Chinese learning is like learn to play the piano; both of them require persistence.
Children have more activities to do these days, sometimes it is very easily to miss daily practice.
The point that I am trying to say is how children spend their time especially when they are young is largely dependent on how the parents organise it.
The knowledge and techniques itself are not difficult, but constant daily practice is a challenge.
If we can be persistent and encourage children to do a daily 5-10 minutes practice for what they have learnt from their weekly Chinese lessons.
The learning outcome would be different, and they will be more confident and proud of themselves for being able to insist on doing one thing no matter how much difficult they have met.
Language learning is not a sprint but a marathon, we need to set a goal and work towards day by day and bit by bit.
After all, to master a language is not the only purpose for our children, but the process of developing a strong stamina, good learning habits and building up self-confidence would benefit our children throughout their whole life.
