Alright, so a health insurance cooperative is kind of like a big group of friends who help each other out when they're sick or hurt. The group is made up of lots of people who all pay a little bit of money each month to be part of it. This money is called a "premium."
When one of the friends in the group gets sick or hurt, the group uses some of the money they've all paid to help pay for that friend's medical care. This is called "insurance."
The good thing about being part of a health insurance cooperative is that you're not alone when you get sick or hurt. You have a big group of friends to help you out and pay for your medical care. And because everyone in the group pays a little bit of money each month, it's usually more affordable than paying for medical care all by yourself.
So that's what a health insurance cooperative is: a big group of friends who work together to make sure everyone gets the medical care they need without having to pay a ton of money.
