1) Introduce it to your students and prepare for the first writing lesson. Remember, each set of letters require two class periods, one to write letters to each parent and relative the student wants letters back from and the second after having received these letters to put them into one self-addressed envelope. Then the student writes a letter to themselves reflecting on letters received and planning and updating their plans for their own future. (At home students could write letters to as many relatives as they want, anywhere in the world, using any language necessary. They mail them.) They write separate letters to each individual as everyone has a different family history with a different set of stories to write about.
2) Introduce this project to parents every chance you get. Let them know that the goal is to help students know their roots and develop their plans for the future, a process that never ends. These will be documents that will help their child start a better awareness of how to plan for the future.
3) From the very start begin to recruit School Time Capsule Project Postmasters. They will be volunteers who help this project year to year in each classroom. They sort letters from the previous year so that they can be handed out to the students each year before the next round of letter writing. It is recommended they be allowed to hand out the letters as a form of reinforcement. If they do not enjoy seeing the positive responses of the students in getting their year old letters back, they may not be the right folks for the job.
Here is one recommendation for directions for 9th through 12th grade students for the first Time Capsule Project writing lesson:
