The South Fork School in rural Weldon, California has involved its students in a number of tree planting projects to benefit local community organizations. The school included the planting as part of the Arbor Day celebration, and in addition to writing reports and reading, students also produced a play on ecology and the rainforest. In addition to working with kids, teachers participate in staff meetings, ongoing training and parent-teacher meetings. Working ten hours a day and weekends is not uncommon for teachers, although many do take advantage of summer vacation to regroup and recharge for the next school year. You don't mind doing that.
Extra time is just a part of teaching.
It's definitely not for everyone. Not everyone is cut out to be a teacher. You work by yourself. You're basically with kids all day, but the rewards are great.
