Hi Everyone! I'm a graduate student in math, and this summer I'll be teaching gifted middle-schoolers in a 18-day intensive program in math. I have experience teaching college students, but definitely not young adolescents, and especially not for an extended period of time. Do you have any advice or broad strategies for keeping students engaged for 7 hours a day? Of course I'll do labs and group work, but does any know of any game types or specific activities that work well? Thanks so much for your advice!
