(CNN)Since the CNN Freedom Project began in 2011, we have reported hundreds of stories about all forms of modern-day slavery.
Teaching children about human trafficking
In that time, one of the questions we've regularly been asked is, how can parents and educators teach children about the dangers of human trafficking?
To answer that, we've collaborated with 3Strands Global Foundation, a non-profit that works to prevent human trafficking through education, employment and awareness.
3Strands Global has compiled educational materials for children of all ages, along with classroom exercises, as an introduction to its full human trafficking prevention program.
