Hi there, @NgoziOnwuemene ...
There are two really good resources that I can point you to. One of those resources is here in the Canvas Community...the other is a set of videos on YouTube from Ashlee Espinosa.
- Set Up Your Canvas Course in 30 minutes or Less - Instructure Community (canvaslms.com)
- Canvas LMS Tutorials for Online Teaching - YouTube
Hopefully these will help you get started creating a module in your course and adding assignments for your students. Sing out if you have any questions along the way. Thanks!
