Before I began my internship, I thought that the experience would provide me with answers… fortunately or unfortunately, as I near the end, I find that I am left with even more questions than when I started. How do you cultivate an environment where mathematical risk-taking – and making mistakes – is encouraged and valued? What is the value of homework? What constitutes a truly rich task? What is the difference between a 78% and a 79%? Random or mixed-ability groups? How long can I continue to function without coffee and a full night’s sleep?
