For many years, our students[0] have used Logo as an integral part of their math circle-style[1] classes. When we started Wally Feurzeig, one of the creators of Logo, was instrumental in helping us incorporate ideas from Logo into the kind of non-standard problem solving that we were striving for. Turtle geometry is a particularly helpful "instrument of the mind" for exploring dynamic geometry. Our co-founder, Victor Gutenmacher, wrote an incredible book[2] on "geometry in motion," which gave a completely different perspective on geometry from the one seen in school and which our students could explore with the help of Logo. For many of our students, especially those with math anxiety, Logo was what enabled them to overcome that anxiety and discover the joy of thinking and tinkering. Many programmers today have fond memories of getting into programming via Logo, but I would argue that despite the current blistering pace of progress, it remains one of the best and gentlest introductions to problem solving and computational thinking.
