Print a big word on the board. It could be almost anything, but the more letters the better. Students must form as many words as they can using only the letters in the word. The students who come up with the most correct words are the winners.
Possible words: tall, ask, bat, ball, etc.
This is a good one for a 5-minute break, or at the end of class.
Make a letter matrix and have students find words that must connect in any way. Bigger matrices provide more word combinations.
A - C - L
J - I - K
M - S - N
R - A - B
Example: milk, link
