This is a set of open-ended reinforcers which includes "Frog and Fly", "Shark!!!", "Killer Whale", and "T-Rex". In each game, the teacher/clinician plays the "predator" that the students/clients are trying to escape. All participants start at the first square. The students/clients take turns producing their target sound/behavior/assignment. If correct, the child is able to move forward. If not, the teacher/clinician moves the predator forward. The object of the game is for all players to reach the safety of the appropriate shelter at the end of the game.
