It depends on what we’re you’re trying to do.
If you have set up a class with yourself as the teacher then you will need to create student accounts for your children. All students can automatically access CS1. If you want licenses to access our additional courses, you will need to contact us to purchase them. You can email firstname.lastname@example.org to do that. We will then send you an invoice, which you can pay with a credit card or PayPal.
However, that’s not what I recommend to most parents.
For someone teaching their own children, I generally recommend the home game over the classroom. You won’t need the student tracking features, and with the home game, your child will get more total levels. If you purchase access to premium material, they will also get additional heroes, hero types (rangers and wizards), premium-only items, as well as access to premium content like the Web and Game Development classes.
You would need to create an account for your child to use – you only need a separate account for your child if you also want to play yourself. Finally, you would purchase a subscription for your child on their account, not yours (this is different from the teacher-student method) by visiting the subscription page: https://codecombat.com/account/subscription
