At the beginning of each month I cut out shapes according to the season or the holiday. Every day we write a number on a shape and place it on the wall around the perimeter of the room. We count each day of school this way. To add a little math to the beginning of the day, we do some quick calculating. For example, 'How many days has it been since day 100, How many days until the end of school, What is 23 + 123, What is 23 x 123, What is divided by 23?' In some instances, the level of multiplication or division has not been taught. Regardless, I put the problem on the board and we work it through. Now, having reached long division, several students know it already just by doing our daily math.
