This is an assessment for Common Core fraction concepts taught in fourth grade. Students are to create a nonfiction book that explains how to complete different activities with fractions. The books can be created with paper and pencil or use of a computer based program. Students need to show two examples for each topic and justify using pictures and words as to why their example is correct. This activity can be completed at the end of the unit or throughout the fraction unit. I have also included student examples of what some of the pages should look like. Their is a rubric included for students to assess their own progress as they go also.
