How to Keep Your Child From Failing Math

Don't let the title scare you!



When I tell people that DH is a math teacher I get a couple reactions, from admiration to the more common confession that they are terrified of math. I know many of you struggle to help your kids, and even wonder how you can keep them doing well in math as they progress.

The first thing I'd tell you is to stop telling yourself that you're "bad" at math. It would be unacceptable for you to go around telling people that you're "bad" at reading, "bad" at writing, and "bad" at driving. You keep that to yourself, because just like negative body image, your kid will pick that up right away.

The second thing that we see is preventable; it's something so simple, so basic, that if you make sure your kids knows it, they will be equipped to handle the math coming down the road...story first:

DH had a long conversation with a parent recently, a parent who was extremely upset at him because their child had 100% on all their math homework, yet scored 25% on the tests. The parent was furious, demanding an answer from him on why their child was failing despite having perfect homework.

DH pulled out the homework; it was full of correct answers--answers...but no work shown. He said he didn’t want to accuse any student of cheating when there’s always room for divine intervention--intervention that happened to desert the child during tests. So, DH made an offer: if the child could set up a problem from any of the homework, not solve, just set up the work, he’d be happy to grant the child an “A.” The child burst into tears. The parent soon grasped the picture.

What’s more, DH said, can you tell me what 7 times 8 is? The child thought for a few minutes and answered “42” then after another minute “56.” Here’s the problem, DH said, you never learned your times tables when you were supposed to, and I bet that every teacher after that allowed you to use a calculator until now, is that right? The child nodded. I suspect that you and your child will have a different type of summer activity planned soon, DH said to the parent.

So how do you help your kids with math, even if you feel inadequate to do so? The very first step is to make sure they have memorized the addition and multiplication tables. Every double digit addition and subtraction in their head. Every multiplication and division in their head. They should be able to answer instantaneously, with zero lag time. They should be able to do this by the 4th grade. If your child can't, you know where to start. Your kid should also be able to to count up to the 12th multiple for the first 12 counting numbers--i.e. 12, 24, 36, 48, etc, all the way up to 144 and back again without an “uhm” or a breath.

How do these things help? Instead of trying to figure out how the numbers all fit together, your kids will be able to concentrate on the problem in front of them. If you can make sure your child knows their tables they’ll be prepared for the advanced stuff. You would not believe how many kids reach high school without basic addition, subtraction, and multiplication--it is the fundamental root of so many kids failing math.

Now you know. And you can prevent it.
