Number Talk Discussion #10

186 ÷ 6

There are a number of ways to approach this problem. Before we look at them, let's define each term of the division problem. 
186 is the dividend, or the number to be divided by another number.
6 is the divisor, or the number you divide by.
The answer to the problem (31 in our case) is called the quotient.


Multiply Instead
"I know 6 times 30 is 180, plus one more 6 gives me 186; so my answer is 31."
