Find the Mistakes Task

Task:
1) Each student will be given a set of conclusions that are fully
proven.

2) The students are to check the logic of the proof for accuracy.

3) If mistakes are found, the students are to document the step(s)
where the mistake(s) occurred.

4) The students should then briefly explain why they felt the logic
was wrong.

5) Finally, a complete logical proof of the conclusion should be
written.

Find the Mistakes Criteria

The students will be assessed on the following criteria:

1) Amount of errors found.

2) Logical explanation of why certain steps were wrong.

3) Organization of corrected proof.
