What you have created is awesome! I understand that it is geared for middle and high school students, but in my experience in teaching Ecology at the college level, there are plenty of students with math phobia who could use your creations to get past their fear and move on to understand the concepts. For starters, I have certain exercises in population ecology that we do as a class, and it does not go over very well doing it the old-fashioned way (walking them through the math). I would love to work with you to develop a more hands-on approach so that they could visualize what the math represents. I am happy to share the materials I have if that is useful.
