Big Ole Sentence
This is a warmup meant to work on concentration and memory.
The structure is simple. The first person comes up with a simple and short sentence. Each next person repeats the sentence, adding another detail. Previously added details can be neither dropped nor changed. The game goes until the sentence gets too long for people to repeat.
The progression could go something like this:
"There is a car."
"There is a red car."
"There is a red sports car."
"There is a red sports car on fire."
