The girls like to play Pictionary and there is no limit to the theme. Camp preparation is a popular one - this idea can be adapted to any part of the program to make it more enjoyable for the girls to learn something new. Easily adapted for adults as well.
Each patrol has several sheets of scrap paper and pencils. A Guider (or parent, senior branch member, etc) has the list and stands an equal distance from each patrol. One girl from each patrol rushes up to get the first word then rushes back to the patrol and begins drawing. The girl that guesses correctly, in each patrol, rushes up to the Guider and looks at the next word. It is up to the Guider to make sure that the previous word was guessed correctly. If you are in a small area, whispering would be wise so the other patrols that haven't figured out the word yet don't overhear. Play continues until one patrol has guessed all the words correctly ahead of the others. No talking is allowed by the girl who is drawing the word.
