Anyway, for this reason as an SLP I've always had a lens on syntax, at least in its functional capactity of comprehending and producing complex sentences. This involves building some syntactic awareness of parts of speech and the functions of words. There is evidence that knowledge of parts of speech and how they go together impacts language and reading comprehension. Approaches like sentence combining are research supported and require this kind of awareness in students.
For these reasons, interactives around parts of speech can be considered on-point in our therapy. Check out Sheppard Software (overall) and their specific ELA interactives. Their Parts of Speech tutorial is adorbs and a fun visual way to explore the functions of nouns, adjectives, and verbs (note also that adjective+noun equals elaborated noun phrase which we can be measuring as microstructure in narrative).

Finding an interactive website of this type is helpful as you can follow the activities in a sequence, which helps with session flow. I have added this website to the Teletherapy Resources List.
As a child of this era also I loved Schoolhouse Rock and have used their engaging grammar videos in therapy to build awareness of parts of speech.
