On the first day of the new month we count out and write in the days of the month together and add the month's activities that pertain to my 5yo. He likes to know what's coming up. We color in the title. I put it and the days of the week in Spanish too.
Then each school day we take a blank sticker and write a weather symbol pertaining to the current conditions. We sing the days of the week song up to the day we're on. We say the date in English and Spanish. I'm using the weather symbols from the book Natural Science Through the Seasons by James A. Partridge. Love all the ideas in this book!!!
I am keeping this interest driven. So, if he gets sick of it, we'll take a step back and possibly just put on a star sticker that day and be done with it. It's pretty flexible and so far he's loving it! Something similar could easily be done in the back of a nature notebook as well.
