After distributing tests left by the permanent teacher, one student rips up his test in front of you. You should:
Ignore it and continue with the test since the behavior is inconsequential.
Tell the student that his/her behavior was not appropriate and give the student another copy of the test.
Look at the student as you continue with the test, and then speak with him privately after the test.
Explain that you will be recording names of uncooperative students for the permanent teacher.
