The more children use and are exposed to a language in the environment they are in, the faster it will be for them to pick up the language. This is why choosing a school environment where English is used predominantly will help your child significantly. When they go home, do also encourage them to share their experience in school with you in English.
Provide your child with good English books which are age-appropriate and interesting to them. Allowing them to browse books in a store will help your child discover the genre they most enjoy reading. Reading is a great way to improve your child’s vocabulary, and parents can encourage a daily routine where your child can spend at least 40 minutes a day reading.
