Hello Ann,
I’m so glad you think CODAP is awesome! I agree that it’s useful at the college level, at least lower division. We tend to say it is designed for grades 6-14. And thank you for posting your comment here on the developer forum.
Thank you for sharing the materials you have developed on population growth.
I couldn’t resist taking the population projections and making a CODAP document out of them. A link to a shared copy of it is here.
I’m afraid our project doesn’t have curriculum development resources, but I encourage you to make use of CODAP with your classes. And any questions you have or desires for features, please post here.
