To cultivate a well-rounded elementary school student in English, focus on the following aspects:

1. Reading: Encourage students to read various types of English books, such as stories, nonfiction, and poetry. This will improve their vocabulary, comprehension, and interest in the language.

3. Speaking: Provide opportunities for students to practice speaking English through role-playing, group discussions, and oral presentations. This will boost their confidence and fluency in the language.

4. Writing: Teach students the basics of English grammar and composition, and encourage them to write regularly. This could be through journaling, writing short stories, or even blogging.

By focusing on these areas, you can help your young learner become proficient in English and develop a deeper appreciation for the language and its culture.
