These units are great for comprehension, test practice, and close reading. They each have a paired set of fiction and nonfiction passages along with a video link for three sources of information. All question sets (between 15-20) questions each are high quality critical thinking questions that automatically increases rigor. Each unit has a compare and contrast diagram and Timeless Toys has three bonus writing tasks. All units are common core aligned and prepare students for the SBAC, CRT, and State Standardized test. High interest reading that hits science standards while prepping for testing! My students love them, especially the videos.
