Want to make sure your students know what a function is? This quick digital card sort is a low-prep way to find out! The activity uses Google Slides to practice or assess if students can identify a function.

The digital cards show graphs, tables, mapping diagrams, and sets of ordered pairs. Students will drag 16 cards onto the correct section ("function" or "not a function").

They can then share with you by emailing their copy or turning it in through Google Classroom. A key is included, which you can remove before sharing with students or keep for self-checking.

Use this to assess that students understand that a function is a rule that assigns to each input exactly one output using multiple representations.
