This is a 25 piece self checking puzzle without any negative operations. It is a fun way for students to review mixed operations in equations. You can use this as a Math Center and has a owl themed version as well as a black and white version.
The puzzle serves as the answer key, so you will need to cut the pieces apart before you give it to the students.
