Here is a Cultural Literacy worksheet on Chicanos, which does a particularly nice job of describing the origins of this proper noun, its use, and the extent to which the words Latino and Latina–or Latinx if you prefer, though that term is of sufficiently recent coinage that it does not appear in the reading–correlate with this word. This is a half-page worksheet with a two-sentence reading and two comprehension questions. Simple and symmetrical, this is a decent, brief introduction to a word Americans really ought to know, understand, and be able to use properly, and therefore respectfully.
