Here is a lesson plan on the Greek word roots homo, homoiao, and homeo. They mean same, similar, and equal. These are extremely productive roots in English; I assume science teachers will recognize the root of two important words in their domain, homeostasis and homeothermic.
I begin this lesson with this context clues worksheet on the adjective similar in order to provide students a hint of the meaning of these roots. Here, finally, is the worksheet at the center of this lesson.
