Many of my classes use the Canvas Learning Management Platform. Most Quizzes and Tests along with other assignments are found here. This link takes you to a video that will show you how to access your son/daughter's course and observe their activity. You can see their assignments and grades and communicate with me through the platform via email. The url for canvas in ABSS is https://abss.instructure.com/.
This is a great tool that emulates the Graphing Calculator we use in class and can be downloaded to a computer or Android mobile device. You must have the TI84 ROM to run, let me know and I can email the file.
