This activity is intended for a group of 4 students, although it can be modified for different group sizes.
Each student is given a sheet with an "all-statement". They must then rewrite the sentence as a conditional statement, and determine whether the statement is true or false. After each step, students can rotate papers and check previous students' answers. Students will proceed with writing the converse, inverse, and contrapositive for each statement, and also determining the truth of each statement.
Ultimately student can compare their results to see which forms of the conditional statement are logically equivalent.
