I know many people have made countdown calendars. I have made several in years past. Time is always a huge factor in this house, as I feel like I do not have enough hours in the day. This calendar is super simple and free!! Those are the magic words "free" and "simple"!! I went to Disney .com and clicked on the preschool page. From the preschool page, click on calenders. On this page you are able to choose which character and calender that works best for you. For obvious reasons we chose Minnie Mouse . Then you can add icons to your dates. We chose the Mickey head for the day we are leaving for " THE WORLD ". Every night before dinner we let our daughter mark off the day. She is so excited about the trip. Also, a great bonus, she is learning math skills in the process.
