Tell the difference between literal language (the exact, real meaning) and nonliteral language (a figurative meaning).
LITERAL language means exactly what it says. NONLITERAL language, also called figurative language, uses words in a way that is not exactly true, to paint a colorful picture. If someone says "it is raining outside," that is literal. If someone says "it is raining cats and dogs," that is nonliteral -- no actual cats or dogs are falling.
Common nonliteral phrases are called idioms. "Break a leg" does not mean to actually break a leg -- it means good luck. Readers need to notice when a phrase cannot possibly be literally true and look for its real meaning instead.
Mastery looks like: They distinguish literal from nonliteral phrases and explain the real meaning behind a common idiom.
Common stumbles: Taking a figurative phrase completely literally; struggling to explain WHY a phrase cannot be literal.
