Storybird offers a free 7 day trial of their program to teachers for up to 40 people on one account (including both teachers and students combined). Any student or teacher added to the account will need to create a free trial account or have a personal membership to join the account.

There is also a family plan version for families to buy and use at their convinience. They also have the option to use the trial for the first 7 days and then they will need to upgrade to a membership after if they wish to keep the platform. The bonus is that the family plans cost the same as a teacher plan.
