I have made a few improvements to my three-week calendar.
You can see my calendar in action here (ignore my to do list & pretend it's complete). This was taken during the week of staff development.
I started out by trying to give myself a guide line so the days were not too slanted.
Then I folded the vinyl back with the letters sticking up. And I gently trying to stick the tops to the board then slowly roll the letters on to the board and remove the backing.
I also made a place for reminders. This allows me to write due dates and reminders and then at the end of the day I send out text reminders using remind.com.
And the toughest part of the project was picking a font and size. I highly recommend printing the text you want on paper and putting it on the board to try it out!
