Today is...
Yesterday was...
Tomorrow will be...
Today will be a good day because...
I model this with students in the beginning of the year and then they write independently in their morning folder. (Great morning day activity.)
I have a calendar.
Weather chart..
Place value chart counting up to 100's day of school...then we count backwards from 80 until the last day of school.
100's board we complete a different pattern every ten days...AB, ABB, ABA, ABC, and etc.
100's day tally marks.
Problem of the day.
And something else but I can't remember.
