What to write on Primary One student name card?

Every day my son will be wearing a name tag to school, do you know what to write on the name card besides the name and class? At the back of the name card, write down the emergency numbers where teacher can contact guardian or parents. You never know when the teacher will need to call you.

This save the teacher's time from going back office ask clerk to find the contact number of guardian or parents. Other than that you can prepare spare name card with detail for the school bag. You never know if the school bag accidently get mixed up with other children's bag.

I do put names on my son's stationery too because i fear he lose them.
