Problem Based Learning How to open a combination lock. Step 1 Turn combination to the right a few times, clearing the previous combinations. Step 2 Now, turn the lock to zero. This is not going to be your first number. If zero is your first number, you can skip to Step 4. Step 3 Now turn the lock to the right, coming to a stop at your first number. Step 4 After turning to your first number, turn to the left, going past your number once. The second time around, come to a stop at your second number. Step 5 Now you must turn the combination to the right once again, to your third and final number. Once you have turned to this number, you can open your lock. Step 6 Now that your lock is open, you can get into your gym clothes (dress out), and continue getting ready for class. If at any time you mess up the combination or cannot open your lock, clear the combination by turning the dial to the right a few times and setting it back to zero. Step 7 Now that your locker is open and you’ve dressed out, put your clothes into your locker and sit down while awaiting further instructions.
