Continue giving your opinions as we started in class. Use creo que and no creo que. Login to eSudio and go to the eBook (not the Workbook), then go to chapter 4 and then to grammar. The activity we were doing is Activity 1. Give it a shot, if you need more practice. I can give you feedback based on what you submit. You could also find the activity in the book on the second page of the grammar section of chapter 4.
