This activity makes a perfect independent/small group center for students to review identifying supporting details and irrelevant sentences for a given main idea.
This product includes the following materials:
Page 1 - A cover sheet to glue to the front of your center folder
Page 2 - An overview of the main idea, supporting details, and irrelevant sentences as well as student instructions
Page 3 - Supporting details sorting mat
Page 4 - Supporting details sentence cards to be cut apart for student use
Page 5 - An answer key
Page 6 - A practice worksheet that requires students to write two supporting details for four given main ideas (answers will vary, so there is no answer key)
I highly recommend printing the mat and sentence cards on card stock for multiple uses.
