Here is a step-by-step, detailed lesson on main idea! Main Idea is one of the big skills that a student has to learn. This powerpoint presentation breaks down main idea into "chunks" or tiny bite-size pieces that students can "chew". The lessons are scaffolded from simple to the most complex and from concrete to abstract.
This lesson is done in the following 6 sessions:
Session 1 - General/Specific words/phrases
Session 2 - Genereal/Specific sentences
Session 3 - Differentiating topic, main idea, supporting details
Session 4 - three-question technique
Session 5 - Stated Main Idea
Session 6 - Implied Main Idea
Of course, you must always procede based on your students' pace and feel free to modify to fit your own teaching style. Get your clicker ready and have fun teaching your heart out!
* I have also created formative assessments to go with each session. It is listed as a separate product.
