Reddit reviews Ed Emberley's Drawing Book of Faces (REPACKAGED) (Ed Emberley Drawing Books)

I did a class once where we focused on drawing faces. It was a fun way to teach different emotions.

I found Ed Emberley's Drawing Book of Faces pretty helpful. He lays out basic principals for beginners and provides these cookie-cutter face parts that students can pick and choose. They're all quite easy and cute. With the more beginner level students, we also talked about different kinds of lines and shapes to further vocabulary. It's a bit hard to get any speaking in an art class though, so if that's your goal you may want to plan something that allows for it.
