It’s the kind of adjective the late, great Joseph Mitchell called a “tinsel word,” and I am hard pressed to disagree. Nevertheless, here is a context clues worksheet on the adjective vivacious. I wrote this, I think, to help native Spanish speakers make the connection between the Spanish verb vivir, “to live” and the use of the Latin roots at its base–viv, vivi, vit, “life, living, live.”
In that role, this document might work well with this worksheet on the Latin word roots viv, vivi, and vit.
