How Can I Help My Child With Common Core Math?

For most parents, excelling in math as a child meant correctly solving linear calculations. They may remember the thrill of answering a complex multiplication problem or correctly solving for an unknown variable. Yet with the Common Core Standards, which nearly all states have now adopted, math is taught in a very different way. Students are expected to understand how and why they are completing problems, rather than simply coming up with correct answers. So how can you as a parent help your child with this "new" Common Core way of teaching math?

Math: Then and Now

Let’s start by looking at the “old” verses “new” way of teaching math.

Imagine your child needs to solve the addition problem 8+9. When parents were young, they likely knew the answer simply from “drill and kill” – or memorizing the addition facts. Yet with Common Core standards, one way students might be asked to solve this problem is using doubles. They’d need to identify the closest double (8+8) and move upwards from there. 8+8=16, plus 1 equals 17. They might also look at a ten frame and see that 8 darkened circles on the frame plus 2 more circles gives us 10 circles (one complete ten frame), plus 7 more on another ten frame gives us 17 total circles.

Now let’s move to the problem 325-27. In the “old” days we learned a basic algorithm for solving subtraction problems with regrouping, starting on the right side, borrowing from the tens, and so on. Yet with Common Core standards, this problem might be solved with the “counting up” method – essentially “counting up” from the smaller number to the larger number using 10’s and 100’s. For example, we’d start with 27. We’d add 3 to get to the nearest 10 and therefore circle the 3. Then we’d add 70 to get to the nearest 100 and circle 70. Next, we’d add 200 more to get to 300 (and circle 200). Finally, we’d add (and circle) 25 to reach the larger number (325). Then we’d add together all of the numbers we circled to come up with the answer. Sounds complicated, right? It is, to many.

Yet the reality is that math instruction is not reverting back to the “old” way anytime soon. The days of memorizing equations and plugging in numbers are behind us, and the wave of understanding and applying math concepts is here to stay, at least for the near future.
