Some of my students have difficulty rewording the statements as conditional statements in a logical order. To support their work, I ask, "What they are trying to say? I find that once the conditional is written correctly, my students can successfully write the converse and bi-conditional correctly.

Using the definitions, students write a conclusion based on the given statement. After about 20 minutes, we will go over the activity. I call on students to share their conditional statements and biconditionals. For each question, I call on more than one student, so that we cover multiple statements and students can practice listening and judging the validity of statements. In order to ensure participation of all students, I call on a student to give his or her answer. If that student doesn't have an answer, I call on another student and then go back to the first student to comment on the second student's answer.

This strategy helps my reluctant students gain confidence and experience. In this unit, students will be using postulates to prove theorems. Understanding the difference between theorems and postulates helps students understand how to write proofs. If needed, I can review the vocabulary in the next lesson.
