This document contains two lists - 15 phrases students need to be able to say, and 10 phrases they need to be able to understand. This page is the very first assignment I give in a Spanish 1 class, followed by a quiz on it after a few days. I have also used it as an opening review exercise for Spanish 2, to help bring their brains back to Spanish class after summer break!
It includes phrases like "May I go to my locker?" and "What page are we on?", as well as teacher phrases like "Sit down" and "Open your books". Once your kids know these phrases, they can conduct most of their basic classroom interactions in Spanish, even from the very first week of Spanish 1.
This two page document includes one page just in Spanish and one page with the Spanish and the English.
