Yeah! Glad I could help!
I ordered the student text and the student workbook, but honestly, we never used the workbook. The student text has questions after each subheading, and at the end of the lesson. I just had her answer most of those questions orally, and then I picked one or two for her to draw a picture of, make a poster, or write it out. So, in my opinion, I don’t think you really need anything other than the student text. 
Also - I almost forgot if you go to Harcourt Social Studies Online:

They have virtual field trips, adventure activities, and you can look at what is included in each book as well. It’s a pretty neat website, and actually FREE. You don’t need a code to use it! Which I love!!
