1. Establish a positive learning environment: provide space for children to express and create freely, and encourage them to express their thoughts and feelings through artistic activities such as painting and sculpture.

2. Provide technical guidance: Although free expression and creativity are emphasized, teachers can also provide some technical guidance at an appropriate time to help children master some basic painting skills and artistic principles.

3. Provide feedback and evaluation: Teachers can give appropriate feedback and evaluation after children finish their works, encourage efforts and creativity, and provide some suggestions and guidance to help children improve continuously.
