Expectations are totally dependent on what you expect your student to learn in what amount of time. The best way to figure this out is by breaking your year into quarters and deciding what you are teaching in those quarters. Obviously the points you want to teach in each quarter are what is expected to be learned. You may want to use a calendar for this. Look at the different seasons, the holidays, and family events that might be happening at certain times. You can spawn learning projects from the culture using a system like this where expectations and lessons are set up using specific times of the year.
You want to make your expectations as detailed as possible but they should have flexibility. They should be reasonable, practical, and realistic. For example, do not state that at the end of the Kindergarten year, the student will be fully bilingual. Keep the expectations per quarter around four and per year around sixteen to twenty. As students get older you can add more expectations or if they are picking up the language at a fast rate, then maybe add more to your expectations the next school year . Your expectations should come out looking something like this:
1. Students will recognize and recite the days of the week.
2. Student will state the correct date of the day.
3. Student will recognize and recite months of the year.
4. Students will describe how countries celebrate the feast of Our Lady of Guadalupe.
Expectations for students need to be linked to what you want them to know. For example, if you have a set vocabulary that you want them to know by the end of Kindergarten put it at the end of your expectations. That way you have clearly added what you expect them to know. For example, if you want your second grader to know body words and clothing words then identify those specific goals below your listed expectations. For example:
Vocabulary for the Weather
Put two columns. In column one have the English words. In column two have the Spanish words.
A set up like this can serve as a way to remember exactly what you want them to know. It makes teaching much easier if you have a guide that you are following. Hopefully with this you can make your own curriculum for elementary level Spanish. Bright Hub Education has many additional resources for teaching Spanish.
