I recently made this for my advanced class, but since it deals with the past tense, it's also usable here, but it is a little bit harder than most material.
The idea is that the students roll 2 dice, with one of them being the first number in the slide called "1st choice" and the second being used in a subsequent "2nd choice" slide. The first number effectively chooses a verb, and the second one chooses a noun amongst a set (though I did change up a few options in those sets, to allow for a few more humorous examples). Then the team makes a sentence about the person who rolled the dice of the form "Yesterday, Peter kicked a monkey." Much like madlibs, this can allow for some rather amusing examples. There are points associated with each verb, and points associated with each noun, so there is a luck game with it too. In general, it's a pretty good attention grabbing game.
