Pop-Up Grammar occurs when a student—not teacher—asks about a particular language feature, and the teacher offers a very brief explanation in order to continue communicating (i.e. interpreting, negotiating, and expressing meaning during reading or interacting). Teachers can use this resource to provide such explanations, or students can keep this resource handy for reference when the teacher is unavailable. Characters and details from the Pisoverse novellas are used as examples of the most common of common Latin grammar.
