I use this simple letter to send home to my kiddo's parents every month or so. I attach any reading work we have done over the course of the month and encourage them to practice it at home!
I've included my actual prewritten note, as well as, a blank template with just the header so you can add your own message. There are five different children to pick from (I usually let them pick which one they want ahead of time but this is up to you!).
You will need Powerpoint to open this file and edit it (you will need to add your own text boxes if you choose to write your own message).
