Below is a detailed two-week lesson plan for teaching Parts of Plants and Their Functions to Grade III students in India. The plan is designed to be engaging, interactive, and aligned with the CBSE curriculum, incorporating hands-on activities, visuals, and assessments to cater to young learners' needs. Each lesson is approximately 40 minutes long, assuming 5 classes per week.
Week 1: Introduction to Plants and Major Parts

Notes for Teachers
- Cultural Context: Use familiar plants like mango, tulsi, and marigold to make lessons relatable.
- Safety: Ensure safe handling of plants (no thorns or toxic parts). Supervise tasting activities and check for allergies.
- Inclusivity: Adapt activities for diverse learners (e.g., verbal descriptions for visually impaired students).
- Resources: If real plants are unavailable, use high-quality pictures or videos.
- Assessment: Monitor participation, homework, and quiz to gauge understanding. Provide feedback to encourage learning.
