There is no right way and no wrong way. Just model for your child by taking a pipe cleaner and putting it in one hole and out the other. This is much easier then regular lacing because the cleaners are stiff and easy to control.
Wanna grade it for an older child? Use different colors and make different shapes/forms and snap a picture. Then give your child different pictures to see if they can copy them.
*Please note pipe cleaners can be sharp and you should not leave your child unattended when doing this task.
