If you teach in the International Baccalaureate Program, part of the English exam is a Paper One Assessment. After your students read Cat's Cradle by Kurt Vonnegut, have them complete this mock-Paper One exam. The students have three prompts to choose from and a passage from the text to utilize for evidence. The rubric for the IB Paper One is included on this resource to make it easy to grade!
This assessment should take an entire class period.
*Even if you do not teach in the IB program, this is still a great end-of-unit assessment for Cat's Cradle and can easily be modified.
