I've taught sign language and Spanish for kids ages 5 - 12 over the last 10 years and here are some of my games I use...some everyone knows and some I've made up to make learning fun. I've got quite a stash of prizes for the kids, too. I collect kids meal toys, freebies from the cereal boxes, stickers, pencils, pens, rulers...whatever I can get my hands on that kids might like and don't cost much or are preferably free. Our local state fair has tons of booths with freebies the kids like.
Bingo...I use this for animals, holidays or just about anything...whatever the topic I'm teaching is. I just print the grids myself and the "numbers" for calling...same thing...just print them myself and cut them up to pull out of a hat.
Simon says....this is a good way of teaching commands and verbs. I use my name...Laura says sit...stand...walk...run...all of the motions are done in place. The kids love this one.
"Family Feud" - I divide the class into 2 groups and have each one come up and pull the "family member" out of the hat. Whatever the student pulls out they have to say in the language. The other side guesses what it is in English. If they can guess it correctly, they get a point. The team with the most points wins. I throw 5 point bonuses in the hat...a simple sentence.
To teach foods, I pretend that the kids have to cook for me. I break them up into small groups and pick a meal (breakfast, lunch or dinner) and they can prepare anything they want, but it has the menu has to be told to the class in the language. I once had some kids fix me hamburgers for breakfast.
For colors and shapes, I have the kids color pictures for me. Sometimes I do the pages as color by numbers so they can see the names for the colors in the language. I've used art projects to teach colors also. I don't know if you've seen the tissue paper flowers, but I let the kids make those in class to teach colors. I had many different colors of tissue paper and the kids had to use the vocabulary to get the materials.
I take whatever games or fun things I can think of to keep the kids interested, which is kind of a shame, but kids today have so many things that are exciting to compete with that you've gotta hold their attention some how.
