CommonLit Elementary Classrooms Target Lessons 7 Reading Comprehension Lessons to Teach Students How to Find The Main Idea of a Nonfiction Text

These easy-to-use main idea lessons will engage students with high-interest topics while helping them hone important grade-level reading comprehension skills.

Target Lessons are highly engaging lessons that teach students critical  reading comprehension skills. Each lesson includes scaffolded assessment questions that build student engagement and knowledge as they complete the lesson. Target Lessons can be used to introduce a new skill or as a form of reading intervention.

Teaching students how to find the main idea is a critical reading skill – but also one that is very challenging to teach. Students can confuse the main idea with the topic of the text or zero in on small details instead of the bigger picture, making it difficult for students to fully comprehend what they are reading. It is especially important that students understand how to find the main idea in elementary school, as texts get more complex in middle and high school.

Luckily, CommonLit has you covered with our main idea Target Lessons! These scaffolded lessons will teach students strategies to find the main idea in engaging lessons students will love.
