This teacher guide was developed to assist teachers of elementary children in their preparation to teach some lessons on rat control. The overall objectives include determining the level of student understanding about rats, developing student attitudes toward rats, developing the student's ability to identify the rat's weapons, identifying those items that rats must have to live, identifying specific acts which students are able to understand to get rid of rats, discriminating between items rats will eat and items they can not eat, identifying and correcting real conditions in the neighborhood, communicating the existence of a rat control problem to the parental group, and reinforcing and testing of the overall program. The plan development includes overall objectives, specific objectives, teacher procedures, support materials, and learner responses and conclusions. A posttest and correction key conclude this lesson plan. (BT)
