Miss Grotke is the teacher of the fourth graders at Third Street. Warm and kind but somewhat eccentric, Ms. Grotke is popular with her students.

She is known to teaching with an "earthy" sort of manner. In "The Substitute", T.J. makes a speech about her saying how she had helped them "... from healing our roots to helping us with our times tables!".

A gifted magician she is also shown to be a karate master in School's Out.

She believes that T.J. and the gang are high spirited children who are not rotten.
