A Way to Make a Summary

In today's class, I had Class 214 and Class 209 read an article on time management for 2 minutes. Then they gave a summary orally. After that, I told them a way to make a summary is to tell the main idea in the first sentence followed by the main point from each paragraph. Take today's article for example. They can start their summary with "This article is about time management," and then summarize the body with "It suggests three ways to manage study time: prioritization, planning, and using time management tools."
