Number of the day worksheet includes questions/prompts based around a class (or teacher) selected number of the day. Can be differentiated for different levels/grades based on the number of the day selected. Some questions include: Is this prime or composite and why? Write a word problem where this number is your solution. Write this number in expanded form (and more!). Could be used as a warm-up, individual/partner activity during math centers, or transition/extension activity.
