Interactive notes with fill-in-the-blanks, operation steps, and space for teacher guided examples. My pre-algebra special education students enjoyed using this interactive notes page because it is simple and direct. I presented the information on the whiteboard while they completed the notes page and tried to make inferences about what would go in each blank. There is a typed answer key included as well as a handwritten key which includes the examples. Once completed, students have a great study guide and step-by-step of how to add and subtract numbers in scientific notation. Aligns with common core standard 8.EE.4.A.
