6th Grade CCSS aligned Common Multiples and Factors Assessment with answer key has 12 constructed response questions. Most problems have space for students to show work. (The other questions do not need space.)The questions also ask students to explain and justify their answers just as the Common Core Standards state. This document also includes an answer key. You can use this document for an assessment, checkpoint, homework, or other activity. Please feel free to let me know if you have any questions or concerns! Enjoy!
