Teachers, save “The Snake Captures the Mice in a Jar, Un…” to assign it to your class.

A hungry snake finds 10 mice on the grass and puts them into a jar. The last mouse cleverly sends the snake on a fruitless hunt for an even bigger mouse and the other mice tip the jar over and escape. Investigate the different ways that ten mice could be arranged when some are in the jar and some are on the grass.
