This is a Number of the Day worksheet that can be used as morning work or as part of a math station. It complements place value units and can be used throughout the year by varying the difficulty of numbers that you select. It could also be used when introducing positive and negative integers. It is a fully-editable PowerPoint file, so you can modify it to meet the needs of your class.
My third graders love it when I randomly select a student each morning to choose the number of the day!
