Big Idea, Strong Support: Understanding Central Idea and Supporting Details for Class 6  

This Grade 6 worksheet helps students identify the central idea of a passage and distinguish it from supporting details.

Through structured exercises, students learn to connect details to the main message effectively.

Exercise 5 – Paragraph Writing  
Sample Answer:  
Supporting details help explain the central idea by giving specific information and examples. In the passage, the central idea is that rainwater harvesting helps solve water shortages. A supporting detail is that tanks were installed on rooftops to collect water, which explains how the system works. Similarly, if we say “exercise is important,” a supporting detail could be “it keeps our body healthy and strong.” These details make the main idea clearer and easier to understand.
