Functions: Mathematical Tasks Input Output Tables and Graphing Functions One of my favorite activities to use in my class are Mathematical Tasks. I use these Mathematical Tasks for partnering activities, group work, independent practice, assessment prep, or in my centers. Included in this set are 10 Tasks, partner and group recording sheets, black and white copies, and an answer key. I created this Mathematical Task for my 6th grade class, but it could also be used in a 7th or 8th grade
