create a division number with a 2 digit divisor. Using more than 1 set of compatible numbers, observe what happens when you estimate using a different divisor, a different dividend, and when both are different.
How is 30 ÷ 15 = 2 related to the division problem 300 ÷ 15 = 20? The basic numbers of 30, 15, and 2 are the same in both, but the dividend and quotient in the division problem have an extra zero.
