Hide and Seek in the classroom

This variation on Hide and Seek proved to be a great no-prep game for my 2nd grade this week.
I divided the class in half.
The first pair sent their "seeker" into the hall for 20 seconds while the "hider" hid a piece of  colored paper somewhere in the room. There was a letter written on it (one of those being taught so far).
The "seeker" returned and looked for the paper all around the class (not in anyone's personal belongings-not on my desk). When he/she found the piece of paper, s/he had to tell us one word beginning with this exact letter. At the end we collected the points gained for the two groups (one point if the piece of paper was found and one point if a word beginning with this letter was found).
 My students knew the purpose of this game was to remember the alphabet letters and words taught with them.​​
