Large class sizes can require a large amount of time and administration. This presentation offers a simple and practical way to take attendance quickly using QR codes and Google Forms. This presentation will also provide ways to automatically pull grades and other information from classwork done via Google Forms into attendance records or gradebooks created in Google Sheets. No prior experience is required, as formulae will be provided and explained. After this presentation, attendees will be able to create their own attendance system, understand the formulae used in the process, and also move data around within the Google ecosystem.
