you can talk the situation over with the school nurse. usually if the school nurse finds out something like this has happened they do a little presentation after recieving permission for the birds and the bees talk with their child as a health science class activity. Your daughter is most likely not the only 10 year old in the class that got her period. and boys that young can also "rise to the occasion" at that age too. my son had to have a talk with our family physician about how bodys change as they are growing at age five when he experienced a rather sticky situation at school and I didn't know how to discuss it with him. Then when he was 8 he had sex education at his school when a teacher was pregnant. So having the school nurse do a presentation will help not only your daughter.
