This "is it a function or not a function" card sort activity challenges students with sorting and comparing relations and functions. This card sort is perfect for getting your students thinking deeper about characteristics of relations and functions and challenges your students to use problem solving strategies to identify functions that they may not have seen before.

The goal of this identifying functions activity is for your students to match each equation with its table and graph to determine whether it is a function or relation.

With 5 matching sets, this function or not a function card sort can be used as an independent cut-and-paste activity or laminated for group work. I love using card sorts as sub plans because the cutting and gluing takes up some extra time and keeps my students engaged for a longer period of time. 

A full set of teacher directions and answer keys is included for this identifying functions card sort.
