In groups of 4-5, students use a real-time, collaborative spreadsheet (such as Google Sheets) to fill out several terms as part of a glossary of code terms they need to learn. If time, they teach one or two of the terms to the rest of the class. Each group is graded on the accuracy of their entries. Then, the class can use the directory throughout the semester as reference material.

This activity can be used for learning HTML, CSS, or other coding languages or frameworks where students need to learn a large number of basic elements and their behavior.
