In this unit, students will learn how to write a friendly letter, address an envelope, and write a persuasive letter. There are so many common core standards that address persuasive writing, and what better time of year than Christmas. Students will write friendly letters to Santa's helpers. In our class we write to our elf on the shelf.... and he writes back! Students also write a persuasive letter to Santa to persuade him to bring them a toy they really want. The students have a lot of fun writing these letters!
