I am a social studies specialist, but I'll be teaching math this summer in a juvenile detention center. I feel comfortable with math, but definitely rusty on actually teaching it. I did ELA and social studies in this setting last year, so I'm familiar with the setting at least. My biggest concern is that I will have kids ages 12-21 in one room with very little resources. Any ideas on things to teach/focus on?
My first idea is mental math/speed math and looking at math in the "real world" like budgeting, etc. The kids I'll teach come and go so quickly and have such varying skill levels and disabilities that it's hard to imagine getting to do an actual unit on anything. Plus, we have limited to no computer access for the kids; most of the time, kids will just have paper and a pencil to work with, maybe a calculator if I get lucky. Any and all ideas, tips, and advice are greatly appreciated!
