The way the calendar is set up is to allow you to write in dates and holidays as needed for each month. It also allows you to fill in what the rewards are for the stickers. You could even white out the number of stickers to change the amount if you would like.
The color code allows parents to see what each color means. I included a number key for “quick talk” with the parents. I personally found it easier and timelier to use the number instead of writing all the messages out each day for each student. *I also included positive “quick talk” in case you wanted to send a special message to your parent.
