Reviewing Vocabulary Game: Throwing a Sticky Ball at a Grid Using Student Generated Sentences

(TESOL Ideas--Any Vocabulary Set)

This is an activity I saw demonstrated when observing a colleague's class.  In an effort to keep track of all the ideas I observe (so I can use them later), I'm going to write about it here.
This game is used for reviewing words from a vocabulary set that the students had previously studied.
The students were instructed to choose 3 vocabulary items from the set that were particularly difficult for them.  They were then instructed to write a sentence using that word for each of the 3 vocabulary items.  They were told that they could make up their own sentence, or borrow a sentence from a dictionary.  (The students had smart phones in which they could search online dictionaries.)
The teacher gave each student 3 slips of paper, and the students wrote their sentences on the paper.  The students were told to gap out the key word, and simply write it in parentheses on the side.  (e.g. "The _________ spins a web to catch insects in. (spider)".
After the students have finished writing, the teacher collects the paper from the students.
The students are put into teams of 3 or 4 people.  Each team draws a grid of six boxes on the whiteboard.
The teacher chooses 6 words, and tells the students to write those 6 words in their grid.  (The teacher dictates the spelling of the words if necessary).
Then, the students stand in a line facing their grid.  The person in the front of the line is given a sticky-ball.  The teacher reads one of the student generated sentences--leaving out the key word or pronouncing it as "blank" (e.g. "The blank spins a web...").  The students throw the sticky ball at the square they think corresponds to the blanked out word.
If the students hit the wrong square by mistake, they are allowed to retrieve their ball and throw it again.  Once they hit the square that they believe is correct, and the whole team agrees on it being correct, the whole team sits down.  Points are awarded for correct answers, and extra points awarded for being first.

As you can see, the game requires some materials (sticky ball, whiteboard, markers, dictionaries or smart phones, slips of paper).  But other than that it is (as the teacher explained to me) relatively low-prep because all the sentences are student generated, and the teacher doesn't prepare anything in advance.
