This unit can be used in multi-grades, but it goes extremely well with the exemplar book Toys! Amazing Stores Behind Some Great Inventions chosen by Common Core on the fifth grade list. I plan to read the book together with the class to get them excited about inventions. I included a textual evidence comparison for this book.
Then, I want students to research an invention of their choice. This project is for the invention they choose. I made an outline for notetaking. It includes a differentiated version for the accelerated or gifted students, also. The rubric will allow scoring for both versions. It would work well as an interdisciplinary unit.
