Jeffrey asks students to think about these statements before he begins
reading. Then, as Jeffrey reads, he stops at key points and asks students
if they notice anything that might help them figure out if each
statement is true or false. Jeffrey records students’ ideas in the “Proof
For” or “Proof Against” columns and then continues reading. Afterward,
Jeffrey and his students discuss the reading, the statements, and the
process they used to determine if the evidence was responsive to the
statement.
