Hi Cassandra and welcome to the Canvas Community! I found a question (Canvas MyMathLab Popup ) that referenced some good student help resources for MyMathLab. The website mentioned in the response to this question, Integrate MyLab Math with Canvas for easy access, has several documents and videos for students to demonstrate how to get started with MyMathLab in Canvas (toward the very bottom of the page). This document has some information you may find helpful as well, https://media.pearsoncmg.com/long/CEPM.selfpaced/FDOCs/Student_Getting_Started_Handout_MyLabMastering_Canvas.pdf.
I hope this helps and you get into MyMathLab easily. If the directions above do not work, you might contact Pearson directly for assistance or perhaps the IT or Canvas support departments at your institution.
