Main idea is a difficult concept for students to grasp. This mostly no prep main idea freebie includes scaffolded, fun activities to help you introduce main idea to your students.

Instead of starting your main idea instruction by having students identify the main idea of a text, these activities help them practice main idea from a variety of different ways.

This is a sample from my best selling resource - Scaffolded Main Idea Practice and Activities to Help Students Build Understanding. The complete resource includes a digital version for use with Google Classroom / Google Slides.

  • Topic Vs. Details - students are given a list of words and asked to sort them in groups based on their topic.
  • Details Should Support the Main Idea - students read 4 short paragraphs and determine which sentence in each paragraph doesn't belong because it doesn't support the main idea
  • Scaffolded Main Idea Graphic Organizer - students read a short paragraph and must determine the main idea and key details of the paragraph using a scaffolded graphic organizer.

This free main idea resource is ideal for 3rd and 4th grade students who are being introduced to main idea, as well as 5th or 6th grade students that are still struggling with the concept.
