I had 2 of my days taken away flast year from my MS to an elem school. However, because I was only there 2 days a week they didn't want me to teach from the book and I had to make my own lesson plans. Which I hated at first because I'd never taught at elem but now I miss it because I started my own routine and the students usually knew what to expect in my classes.

This year I have 3 schools (1 MS and 2 elem) I still go to elem 2 days a week but now it's split up into two days two schools. Both use a different text book. One school doesn't care what I do as long as I teach my parts of the book.  The other elem school doesn't like me deviating from the book at all. I guess they want me to reinforce what the students are learning in class. 

It's a little hard but depending on what you like it can be great. The kids have more energy than MS and you are usually done teaching by 2PM. Although you may have most of your classes back to back instead of like the MS where it can be randomly throughout the day. Or if you have afternoon classes you wouldn't be done by 2PM but those can be whatever you want. Good luck! If you have more Q's feel free to PM me. :]

I've worked High, Middle and Elementary schools.  I think the biggest shock I  had is that it takes so long for students to do a basic task like cut some paper and write things down.

In Elementary School you are supposed to teach lessons with your co teacher.  Some Korean Teachers let you get on with it where as others like to micromanage and don't understand that you are actually there to teach. 

As far as advice goes just be aware that your classes will probably be mixed ability.  I have one class with students who cant write Korean  in with high levels students who attend Hagwons to study English.

Key differences I found (+ advice):

> Elementary is more organised - the calendar is set waaaaaaay in advance and there are far fewer sudden timetable changes (my middle school constantly changed things on everyone despite having a yearly calendar).
So ask for any special dates you need to know. I wasn't involved in any school events in middle school while in elementary school I'm a part of Sports Days, Teacher Introductions, Parents-Teacher Days, Fire Drills etc.

> More teachers will speak to you in elementary school.

> Elementary schools focus more on communicative ESL learning - so games, activities and so on. Middle school is focused on testing.
Start collecting varied games and activities, especially games that get students off their chairs (think of your childhood games and how they can be adapted to lessons). The activities/games should be varied enough that the kids don't complain but you should keep in mind that if it's a good activity your CT will use it in his/her classes too, so your kids will get bored easily (I try not to use something more than 3 times a semester).

> Instructions have to be really, really clear and simple. If the explanation involves more than 4 sentences then more often then not it isn't worth it.

> Some CTs are fine with activities/games that last 5 minutes while others like activities for 20.

> Less bomb games. My CTs in middle school only did bomb games. In elementary school bomb games are more of a I-messed-up-and-didn't-plan-so-let's-do-a-bomb-game thing.

> Pray you don't get an afterschool that has combined classes of Gr 3-5. Or worse, grades 1-5.

> If you get asked, level your afterschool classes but DON'T call them "Basic" or "Advanced" classes. Call them something innocuous like the "Dandelion" and "Butterfly" class. All the mothers believe their children should be in the advanced class and they will fight to get their kids into that class. Also, keep the tests in case you have to have any discussions about their child's actual ability.

> English books that we read during our childhoods - the classic stories - are classics for a reason and the kids love them here too.

> Middle school camps can be activity based (actively practising their English) but elementary camps need to have more teacherly lessons with/and then some activities. Don't try to do an activity-only camp with kids without any English ability unless you're very good and very confident that they can come out of camp having learnt something.

In elementary I think you can be a bit more silly in class and have more fun. This of course depends on your coteacher. In my main ele. school, my coteachers have been great! In my rural one I have no coteacher, so the kids can be hard to control, but I can do whatever the hell I want as long as I complete my parts of the textbook.

I miss middle school though because I could actually have some meaningful conversations with some students. This applies to elementary school, although more rarely, as the students' English is much less developed on average. That doesn't mean you can't build a close and lasting relationship with them, just it takes a bit more work.

Good luck! I also had to make a similar transition after my first year, and actually had to move cities as well. I was pretty sad and nervous, but with an open mind, you can adapt to almost anything!
