Common Core Division

Common core division uses partial quotients. For example, if you divide 136 ÷ 8 you would start by guessing how many times 8 could go into 136. Let's try 10 times, so that would be 80. We have 56 left over. We continue to repeat the process for the remaining amount, how many times does 8 go into 56? That would be seven times. Then you add the numbers together 10 + 7 = 17. So the answer is 17.

Common Core Division “Friendly” Numbers Explained

Break down numbers into “friendly” numbers. Breaking down numbers into easily divisible numbers is important to learn for number fluency. This may seem a bit tedious, but understanding how to break large numbers into easier-to-manipulate numbers can build children’s mental math capacities.

Break down 260 into the “friendly” numbers 250 and 10. I chose 250 because it’s the divisor, 5, multiplied by a big number (50). I choose 10 because it’s the difference between 250 and 260. These go inside the boxes of the area model. Divide each one by the divisor to get the factors, then add the factors together.
