This is a digital activity. It is a puzzle in Google Sheets. There are 12 questions that can be answered using the quadratic formula. As the students answered the questions correctly the box turns green and part of the picture is being colored. If they answered incorrectly the box turns red. Thus, this activity gives direct feedback to the students.

You can share this with the students using google classroom (always make a copy for each student) or via email (change the last part of the link to copy) or any teach platform.
