Summarising
Purpose of Summarising
- Summarising follows note-making and is used for reporting main points.
- It involves selection and paraphrasing of important information from the original source.
Steps in Summarising
- Underline important ideas.
- Write them down, abridging the verbs.
- Avoid examples, explanations, and repetition.
- Expand points into full sentences and link them with suitable connectors.
Example Transformations

Green Sahara Summary Example
-
Original Points:
- The Sahara is the world's largest desert with low humidity and rare rainfall.
- Beneath it are vast aquifers of fossil water.
- 6,000 years ago, the Sahara was green, supporting hippos.
- The green Sahara resulted from paleo-monsoon migration influenced by Earth's axial tilt.
- Climate changes led to rapid drying, transforming the Sahara into its current state.
-

CBSE Exam Tips, Important Questions & Common Mistakes to Avoid
Common Mistakes and Exam Tips
Common Pitfalls
- Overly Detailed Summaries: Students often include too much detail in their summaries, making them longer than necessary. Aim for brevity while retaining key points.
- Neglecting Key Ideas: Important concepts can be overlooked when summarizing. Ensure all main ideas are included.
- Improper Paraphrasing: Simply changing a few words in the original text does not constitute effective summarizing. Focus on rephrasing ideas in your own words while maintaining the original meaning.
Tips for Effective Summarizing
- Follow a Structured Approach: Use the steps of note-making as a guide: underline important ideas, write them down, and avoid examples and repetition.
- Use Connectors: When expanding points into full sentences, utilize suitable connectors to enhance the flow of the summary.
- Practice Precision: Be precise in your expression to ensure clarity and conciseness in your summaries.
- Aim for a Target Length: A good summary is typically one-third the length of the original passage. Practice reducing summaries further to improve conciseness.
- Focus on Main Points: Identify and emphasize the main ideas while omitting less critical information to create a more effective summary.
