I have loads of these, some may or not work for you, I might be trying to teach my grandmother to suck eggs so to speak but help yourselves:
Primary Level (Ofcourse)
Numero Uno "Vocabulary/Memory Game"
Materials: Vocab words one set say 10 words on an A4 sheet of paper with a letter on the back A-J, Definitions on seperate pieces of A4 with numbers written on the back, some sticky tape, be careful sometimes the print shows through white paper so something which makes the A4 less opaque is better. Trivia questions from some previous chapter of a particular book will do.
Tape the paper onto a wall in view of the students, with the letters and numbers facing them.
Start the game by grouping the children, small groups will do and draw a scoreboard onto the whiteboard.
Explain the rules: A member of your team must answer the trivia question correctly, should they get the answer correct they may choose a word and definition, if the word and definition matches that team wins a point.
Be warned this game can go on for a while by which time you might lose their attention.
Ask a question, the student answers the question, chooses a word and definition, read both vocab and definition out allowed, should they get the answer correct then they win a point, if not then tape the word and definition back to the wall.
Etc etc
Number Two: Hot Potato
Materials: A potato (If you can find) not a hot one obviously, possibly a stick of dynamite might have a better effect ofcourse a prop, etc, chairs to fit students, a tape player (CD) alternatively you could get the students to sing a nursery rhyme you have previously taught or something similar, if you are musically talented and have a guitar that will do too and ofcourse students
Rules:
Music is played and the hot potato/etc is passed in the circle until the music stops, whoever it lands on must do whatever you might decide, recite the alphabet etc etc etc
Number 3: I went to the market then my basket broke
Objective: Students learn went and some basic grocery vocabulary.
Materials: A4 paper, colouring pens, chairs and students
Introduce the game by asking the students to draw some groceries that their mums or dads might buy from the grocery store, supermarket etc. Ask the students to label the grocery with its name, then have the students sit down.
Rules:
A shopper walks around in a circle calling out grocery items, when the person doing the shopping calls out the grocery that you have you must follow that person, when the person shopping says "then my basket broke" you must quickly sit down, by which time somebody has taken away a chair so that leaves a student stood up, that person then continues the fight for the chair and in the meantime also introduces them to new vocabulary.
This one isn't actually a game but the US armies drill song, you know the one "I want to be a drill inspector...." anyway I have been using that tune to drill pluralisation rules, such as o,x add 'es' etc, it seems to be a catchy number so it seems to work, possibly only suitable for prathom 2 up though, and a worksheet might help with a few examples too.
Other resources I find invaluable are:
http://www.primaryresources.co.uk http://www.englishgrammarsecrets.com and
http://owl.english.purdue.edu/handouts/esl/index.html then for science documentaries Microsoft Encarta kids and premium ofcourse there's also DK Multimedia, Encyclopedia Britannica,
http://www.sfscience.com and Wikipedia.
I have to say for Primary level Scott Foresman books are really good and are filled with scientific inquiries, the teacher's guides are excellent and if you go to the back of those books they are filled with useful information and key considerations for an esl classroom, word semantics, religious beliefs the works.
By the way if anybodies interested in a bunch of graphic organisers that can be photocopied and distributed, which are basically all the scientific process skills that primary levels learn then feel free to pm me, I can either put them on a server to download or email them to you, bunch of stuff their from 2-5 column charts to venn diagrams etc.
Hope those help or pass some time that you might have
Regards
Ben
