Great math center activity, great for independent work time. This math mystery allows kids to discover four things that the Grinch stole on Christmas. These are 4th grade standards. This activity will take students between 20 and 45 minutes depending on their level. I also have a 5th grade Grinch mystery. Concepts are similar; however, standards are for fifth graders.
Thanks! Hope your students enjoy :)
