Heck. Yes. Our curricula, activities, and resources are all uncopyrighted, and reasons like this are WHY THAT IS SO EXCITING FOR US. So you have our permission 100%.
Here’s one word of caution: people often think they need to customize our Foundational Curriculum for a ton of reasons (their group is more “advanced,” or older, or younger, or more rural, or more urban, etc.), and we’ve found that people often overestimate how much tailoring is needed. If you have the ability, put a small pilot group together of your population and try the curriculum on them before you start customizing things. It might just work — or it might not work, but not in the ways you were expecting.
Oh! And tell us about it. This isn’t required, but we love hearing about the different ways people are putting the curricula to use.
