This Number of the Day activity page is appropriate for students in 2nd, 3rd, or 4th grade. The "number" you choose to focus on should be easy to use for multiplication and division purposes. For example, you may want to start with two digit numbers that are multiples of 10, then go to multiples of 5, then multiples of 2, then multiples of 3, 4, 6, 7, etc. Once students have gained a strong sense with two digit numbers, then move on to three digit numbers that are easy to divide. Also, the smaller "boxes" within the Number of the Day are meant for the "number" you choose to use for each page.
