Central Idea and Summary
Aligned to RI.6.2 — Common Core State Standards for English Language Arts.
What this lesson teaches
The central idea is the main point a text builds through its details, not just its subject. Find it, then summarize using only what the text says — no personal opinions.
Worked examples
Example 1
An article on bees lists their role in pollinating crops and their recent decline. Subject: bees. Central idea: bees are vital to food supply and need protection. Objective summary reports those facts without adding 'we should all care.'
Example 2
An article on antibiotic resistance has the central idea that overuse creates it, supported by hospital data and a timeline of resistant strains.
Example 3
A summary that includes the most interesting detail but not the central idea is a summary of the wrong thing.
Practice questions
- State the central idea of an article in one sentence, then list two details that support it.
- Write a 3-sentence summary using only the text's information.
- Cross out any opinion words that slipped into your summary.

Idea Central y Resumen
La idea central es el punto principal que un texto construye con sus detalles, no solo el asunto del que trata. Identifícala y luego resume usando solo lo que dice el texto — sin opiniones personales.
Ejemplo 1: Un artículo sobre las abejas menciona su papel en la polinización de cultivos y su reciente disminución. Asunto: las abejas. Idea central: las abejas son vitales para la producción de alimentos y necesitan protección. El resumen objetivo reporta esos datos sin agregar 'todos deberíamos preocuparnos'.
Ejemplo 2: Un artículo sobre la resistencia a los antibióticos tiene como idea central que el uso excesivo la genera, apoyada en datos hospitalarios y una cronología de cepas resistentes.
Ejemplo 3: Un resumen que incluye el detalle más interesante pero no la idea central es el resumen de otra cosa.
