Welcome, @Mikaila, and great question! Our curriculum is written in such a way that allows it to be used in a variety of settings - in classrooms, Mozilla Clubs, after school programs, and even personal use/learning, to name a few. They are easily scaled to accommodate different ages and different size groups.
In short, the framing of the curriculum is geared toward someone who will be teaching learners the lesson, but it's still left very general.
You can find some fun Thimble remix examples from other community members in this article.
