Hi @sheila_henke
Welcome to the Canvas Community!
You have asked your question in a global community of Canvas users who can only access their courses and accounts, and are likely unable to answer your course-specific question. Luckily, many of us have some experience with Pearson's MyLab & Mastering. however, before I share some resources I must tell you that your first resource for course content questions should always be your instructor. You can learn how to contact your instructor in Canvas at How do I send a message to a user in a course in the Inbox as a student?
I hope this is helpful, and good luck.
Kelley
