Have you checked if your textbooks are on here? Even if your exact book isn't, you can probably find similar lessons and see what other teachers put together.

I think extra activities are a good idea. What's your usual class structure? After a brief warmer (which for me is a good time to try and build rapport with the students), I typically have a PPT that takes up a chunk of time in the beginning, anywhere from 10 - 20 minutes (during the slides, I ask questions and try to interact with the students as much as possible). I also have super small class sizes so I take advantage of that and spend more time on speaking practice with each individual student. Like we'll practice as a group but also as individuals. Then I have 2 - 4 activities. Usually we rarely have time for more than 2!

Not sure if any of that is helpful, but feel free to ask more questions!

Oh thank you for the suggestion! I actually just signed up to post this question so I wasn't exactly sure how to use this website. I found some sections about my textbooks so I guess it could be helpful when I am running out of ideas.
Today was my first full on teaching day. Since it was my first time to meet each class, I tried to do a short introduction and using the vocabulary the textbook assumes they know and trying to see where everyone is at. I plan to start the next lessons with a quick review then a warmer to lead into the current lesson.
I've been trying to make PPTs for some of my classes but I haven't found a huge difference from my classes that had PPT and the ones that didn't.
I usually teach the content that's in the textbook but getting the students to practice that with each other and also drilling vocabulary as well as using the CD content and then finishing with a game.

My experience with teams

1.  Put your class into teams.  Have at least three teams.

2.  I would do the points on a PowerPoint (what I do I include in this post to give you an idea of what I do).  You can get piggy banks (or something) and give little balls if they answer a question or something.  However, that might cost a lot of money, about 50,000.  If your school is willing to buy it, then go for it, but don't use your own money if you are new.  I used mine.  That is how I know the costs of things.   However, I was on my second contract when I started doing points.  I really loved my school.  I spent my own money out of appreciation and love for the school and students.  You may spend the money and regret it because your school doesn't like you or you don't like it for some unknown reason.  I certainly didn't regret it because we established a good relationship.  The cheapest thing would be to add point on the PowerPoint from the computer. 

I tried doing things on the board, but doing stickers on a board is time consuming.  Students may come up and either try to add or subtract as well.  At least with the PPT, on a USB, you have more control over the points.

I would write on the board points.  Students would run up and erase them before I had a chance to count because they were so competitive or jerks.

3.  I have a two point systems at my current school. 
My first one is that I keep track of points of each team.  The best team at the end of the month gets candy.  At my last school I would give nicer prizes twice a semester, before midterms and finals.  You choose what you want.  Save up and then buy nice prizes or just buy cheap stuff but give it more frequent.  Both things work well. 

The second point system is a class point system.  I will include it in this posting.  It is extremely simple, but my CTs like it.  The basic idea is that if the class is good, they get a reward such as a day of English games or they get to choose their seating arrangement.  If they are bad, they write till their hands hurt.

3.  Again, coordinate with the school on buying things.

4.  You mentioned stickers.  That isn't bad.  Unfortunately, it really is hit or miss.  One year I went to America.  I got a bunch of really cool stickers.  Scratch and sniffs even!  They weren't too impressed.  Candy is pretty much a sure bet.

I know this is a lot, but I have tried a lot with teams.  This is what I have learned.  I might have forgotten something.  I hope this helps.
