This product is a one page document that has a Scoring Guide for a Friendly Letter. The beauty of this is that if instructed correctly, everything the students need is listed on the document and they are simply following set criteria. I would set this Scoring Guide in the 3rd - 6th grade range, with you being able to adapt it based on the group of students.
Included on this Scoring Guide are basic guideline within this format. You can modify any of the subheadings to ensure the students are learning in the correct direction. There is also a point total on this document, though you can revise it to best meet your needs.
I instructed Friendly Letters for a number of years, and I would introduce the concept, go over a few sample ideas, and then examine this document with the students. By following that process, everything would go smoothly, plus I always physically mailed the letters. I would suggest completing this earlier in the year, being that some individuals (typically favorite teachers) may take longer than others to reply. The student excitement is always high when a reply letter comes!
Thanks for viewing this product; feel free to examine some of the others in my store (including a business letter scoring guide that has a peer evaluation within it).
