I am a third grade teacher and use workstations in my room (D. Diller). Last year, I had a group that was very low and had quite a few behavioral problems. I put the students into pairs to work together at the workstations ~ usually boy and girl ~ to cut down on the socializing.

I have my students complete a spelling contract each week. The students are responsible for completing enough work for points to get the grade. There is a scale

the top that lets them know the required points needed to achieve an A, B, etc. They also have to fill in their goal for the week in points and sign for accountablilty. Some of my workstations address some of the items on the contract to help them fullfill their obligation by Friday.
Some of the workstations:
Letter tiles: give 8 letters ~ 3 vowels/5 consonants ~ spell as many words as you can using the letters provided. You can even have them compete (which my students loved) by giving points for 3 letter words, 4 letter words, etc., adding them up, and seeing who received the most points that week.
Listening center: books on tape, create a book on tape, respond to a book they have listened to on tape, etc.
ABC order and reverse: write spelling words in ABC order and then turn them around and do them in reverse order
Proper/Common Nouns: using a newspaper and highlighters, highlight nouns in the paper. On a sheet of paper with 2 columns, write each noun in the right column ~ proper or common.
Write a story using spelling words
Rainbow writing of spelling words
Hangman with spelling words
Draw a picture and "hide" spelling words in the picture
Verb charades
Magnetic words: on a cookie sheet, spell spelling words with magnetic letters
On the line: using clothespins, write letters on the clothespins ~ spell the spelling words by clipping the clothespins onto a ruler
a station for working of the spelling contract: such as cut out the words/letters for spelling words and make a collage ~ make a word search ~ make a crossword puzzle ~ make a puzzle
Debbie Diller has a few books that could help ~

least they did me! ~ Literacy Workstations: Making Centers Work & Practice With Purpose.
Hope this helps.
