To teach English in junior high school, it's essential to engage students and make the language relevant to their lives. Here's a sample lesson plan:

1. **Warm-up**: Start with a quick greeting and ask students about their weekend or recent events. This helps build rapport and gets them comfortable speaking English.

3. **Grammar Focus**: Choose a grammar concept that's age-appropriate (e.g., present simple, past simple). Use fill-in-the-blank exercises, sentence rearrangement, or role-plays to practice.

4. **Communication Activity**: Organize a group discussion or debate on a current event or popular topic. Encourage students to use the new vocabulary and grammar structures they've learned.

Remember to tailor your teaching style to suit your students' needs and learning preferences.
