Central Idea and Objective Summary
Aligned to RI.9-10.2 — Common Core State Standards for English Language Arts.
What this lesson teaches
A central idea emerges gradually as specific details accumulate and reshape it. Trace how it develops across a text, then write an objective summary that reports the ideas without inserting your opinion.
Worked examples
Example 1
An essay on sleep may open with a personal anecdote, add research on memory, then cite school start times — the central idea 'sleep loss has measurable costs' only becomes clear once those details stack up.
Example 2
An objective summary of a persuasive essay reports the argument without joining it: The author argues that later start times improve attendance, citing district data and a sleep study, and acknowledges the bus-routing objection. Note that argues and citing attribute every claim to the author — the summary describes the piece rather than agreeing with it.
Example 3
Common mistake: putting your opinion into a summary. Adding and she is right, or convincingly shows, turns a summary into a review. An objective summary reports what the text says, in proportion to the emphasis the text gives it, using attribution verbs. Your evaluation belongs in a separate paragraph, clearly marked as yours.
Practice questions
- State a text's central idea in your own words.
- List two details from different points that shaped it.
- Write a two-sentence objective summary that adds no judgment of your own.

Idea Central y Resumen Objetivo
Una idea central surge poco a poco a medida que se acumulan detalles específicos que la moldean. Sigue cómo se desarrolla a lo largo del texto y luego escribe un resumen objetivo que informe las ideas sin insertar tu opinión.
Ejemplo 1: Un ensayo sobre el sueño puede abrir con una anécdota personal, sumar investigación sobre la memoria y luego citar los horarios escolares — la idea central 'la falta de sueño tiene costos medibles' solo se aclara cuando esos detalles se acumulan.
Ejemplo 2: Un resumen objetivo de un ensayo persuasivo reporta el argumento sin sumarse a él: La autora sostiene que empezar más tarde mejora la asistencia, citando datos del distrito y un estudio del sueño, y reconoce la objeción sobre las rutas de autobús. Nota que sostiene y citando atribuyen cada afirmación a la autora — el resumen describe el texto en vez de coincidir con él.
Ejemplo 3: Error común: meter tu opinión en un resumen. Agregar y tiene razón, o demuestra convincentemente, convierte el resumen en una reseña. Un resumen objetivo reporta lo que dice el texto, en proporción al énfasis que el texto le da, usando verbos de atribución. Tu evaluación va en un párrafo aparte, claramente marcado como tuyo.
