Ladders

Have the kids sit in a line in pairs with their feet touching so they make a kind of obstacle course.  Give each student a vocab card that will come up in a story (both people in the pair have the same card).

You read a story and when they hear their word they have to stand up and race their partner over the other kids legs, around the outside to the start of the line, then back to their place.  There is no winner, they just keep running and listening for their word.
