Can I assign groups of content?

I'm hoping I'm just doing it wrong, but it seems I have 2 choices when I want to assign content:

1. I can separately assign every piece of the content I want students to do. (Problem: Students get confused by the many separate pieces of the assignment & don't know what order to do them in.)

2. I can assign the 1st portion of the module (usually a video) & then tell my students to do the whole module. (Problem: They apparently don't see the module unless they click on the blue title, which is confusing, so many students just do the video & honestly think they're done.)

What I want is to be able to batch the whole module on, say, converting fractions into 1 assignment. Is this possible?

Thanks!
