This sample comes from a K-2 class, but can be exactly as effective for an older audience. Just follow the three steps and their schema (prior knowledge) will build faster.
STEP 1- Introduce 6 basic statements in the target language using pantomime, song, rhyme, or a game. ALWAYS show the written version on the board. NOTE THAT THE SYMBOLS (tildes, question marks) are added separately to call student attention.
Model the answers and add illustrations. Ugly or pretty, read out the answers.
STEP 3: Transfer the lesson onto paper/pen/computer
Repeat the reading aloud. Tape it if needed and re-play. Do 3-6 basic questions statements at a time until they are mastered.
