This is painfully simply but I'm goign to use the Pyramid Game as my activity for this lesson:  Here's how it works.  There are 6 levels to the pyramid with a subject within each level and an animal next to it.  The students must walk around the room making the sound of the animal (so initially all students will be mooing)  they must find a student making that same noise and each student in the pair should ask "Do you like...?" of something in the subject of the level they're on.  Each student can answer either "Yes I do." or "No I don't."  Then they will play rock, paper scissors.  Quite simply, the student who wins goes on to the next level.  Not a whole lot of strategy obvioulsy but it gets them speaking English and I find they still have fun.  Oh, and once they reach the top, they come and ask the teacher.  If they beat the teacher in rock paper scissors, they become the "teacher" which they also really enjoy.  To keep order and ensure they're all speaking English, I just wander about the room.  Students who are simply playing rock paper scissors (as they're apt to do) have to sit down.

Being in Korea has eroded my English to the extent that I had to double-check on Google, but you mis-spelled "hamster".

Simple survey to get the students asking and answering questions.

I've tried to use your powerpoints before but for some reason when I download them they don't work. I don't know if it's just my computer.

The PPT links should work in this post. 

If the PPT link is in .pptx format, it does not work well in Internet Explorer.  You can use option 2 below to open it.

But, the .ppt format should work in IE.  Just click then answer "open" instead of save.

Below are two options for opening any PowerPoint.
 
Options:

1.  Use Firefox as your internet browser.  Clicking the links in Firefox will allow you to open the PPT or pptx directly in a way that works.

2.  If you are using Internet Explorer - right-click the PPT link, copy the link address - then - open PowerPoint, click to Open File - then - paste the link address.

After you have "open"ed the PowerPoint, "Save As" on your computer.  It should open for you in the future.

Have you tried different computers?

I always check posts at home and at school.

I checked the links in this post at both, using Firefox and IE, and it is working for me.

I stole the format from someone else who used two balls for the pass the pencil case game. One ball will be the "question" ball and the other will be the answer

I tweaked another's ppt and template for this intro ppt and snakes and ladders game for my class. Thanks to the original posts.

Here's a variation of the Mario game - the kids seem to enjoy Pokemon. I can't remember who I got the Pokemon template from, but it's awesome!

Here's a ppt for Lesson 6 vocabulary.

We printed out the slides with the vocab and later used them for a guessing game.

1.  Tape the vocab words to the board, and divide the class into two teams.
2.  One person from each team comes to the front. Student 1 turns away and closes his/her eyes. Student 2 points at a picture while the class quietly watches.
3.  S1 turns around and asks, "Do you like (any word on the board)?"
     The class responds, "Yes, I do. I like ________ ." or "No, I don't. I don't like _________."
4.  We gave S1 three tries to guess the correct word. 1st try = 3 pts, 2nd = 2 pts, 3rd try = 1 pt.
5.  If S1 did not guess the animal or food, then S1 asked S2 "What do you like?" and S2 responded.

Just wanted to say that I used your game idea yesterday and my kids went nuts! They were beyond excited when they got to say "No, I don't." and completely devastated when they had to say "Yes, I do." Thanks for the idea! Perfectly simple prep and explanation.
