<div dir="ltr"><div><div>Matthias, thank you so much for your response. Coming to Racket has been exactly what I needed to take an interest in programming and education and find a path that works! I will definitely follow through with learning the 2htdp/universe teachpack (which was on my list anyways), and hopefully I can help make a bridge between Minecraft and Racket so there's a simple and familiar 3d building environment to work with.<br>
<br>I am actually interested in trying to introduce programming ideas to children as young as 5 or 6. Much of the mathematics taught to children at this age in the Montessori school I work at is embedded into physical materials. I'm trying (with my purely amateur understanding) to come up with activities that can start teaching the fundamental thinking skills that HtDP seems to be aiming at. Minecraft seemed like a good replacement for actual real-world building blocks. I was hoping some examination of building structures via recursion, and building more complex things out of simpler programs would be helpful to teach children who don't already have a familiarity with algebra.<br>
<br></div>Daniel, my first experience with programming as a child was LOGO and turtle graphics. Perhaps that is why I still have an affinity for the Lisp family. I was actually hoping to implement some kind of turtle builder into the Minecraft Pi world. However, it seems like the Turtle graphics style of programming is very different than the HtDP/Bootstrap way. Are there thoughts about that? For young children, those kind of robotic instructions seem to make more sense, I am at a loss to find ways to make recursion and functional programming more concrete.<br>
<br></div>Thanks again for being responsive to my questions. Without any formal training in either programming or education, I can use any help I can get to pursue my ideas.<br><br>-grant<br></div>
