This is a packet aligned with the 5th grade common core standards dealing with adding and subtracting decimals. (It could be adapted and used with any concept). There are I can statements listed at the top. Directions for the task are also listed, as well as a section to brainstorm ideas together to get the students started. The students write 6 story problems of their own dealing with adding and subtracting decimals. They must then create an answer key to their problems. They will trade with a partner and answer their story problems on a worksheet that is included. Finally they will grade their partner's paper once they're partner has answered the story problems. Included are the instructions, brainstorming map, a blank key for them to write their answers. Blanks and numbers to write their story problems, as well as a place to answer their partners questions. Great activity for incorporating real world examples, story problems, and critical thinking skills.
