At the end of each day students color in the correct smiley face depending on how their day went overall. I have them color red for the sad face, yellow for the upset face and for the smiley face they can choose which color they want. Students take this home each night with their homework and bring it back the next day. At the end of the week I have the parents sign and it then goes into their folders. This has worked great for me in my classroom and has allowed me to interact with the parents on a daily basis!
