Go Math Part 1

This will begin a series about our new math program. I have included a great article at the end of this blog, written by Solomon Friedberg, the chair of the math department at Boston College.

Kindergarten Math/Reading – Mrs. Gore had her Kindergarten students guess the number of seeds in a pumpkin, and then write the number. They had read books about pumpkins, and counted pumpkins as they read. This is a good example of integrating math in another subject.

Unlock the problem

Our new math program asks students to really think about math, rather than just memorize facts. Memorizing facts is still important in order to be able to do the math within the complex problems. You may have noticed that math homework is taking more time because of all of the complex problems, and the explanations. As students get used to doing these problems, they will be faster. Math in the real world is generally more complex than a simple computation. We usually have to think about what kind of math we need to solve real world problems. If I want to tile my kitchen counter, I have to know more than the formula for area. I have to know how big each tile is, and how many I will need for the surface area I am covering. Knowing basic multiplication is very helpful, but only after I figure out what I need to multiply. Underlining the actual question in a word problem, and then looking for the important information in the problem, are essential skills to solving complex math problems.

How have you used math in the past week? Was it just a computation? Did you simply use an algorithm, or did you need to do more than one step to find your answer? As you see yourself doing math in your day-to-day life, point that out to your children so that they see the value of problem solving and fact memorization.

Common Core math is not fuzzy: Column

Solomon Friedberg7:43 p.m. EDT September 15, 2014

Real fluency is an improvement on traditional math’s plug-and-chug, mechanical approach.

Common Core math is getting the works from critics: It’s too demanding for most kids; holds back the speedy kids; not the same as what parents already know; makes kids cry. It even promotes “fuzzy math.”

As a professional mathematician, I’m as firmly against fuzzy math as they come. Common Core lays the foundation for students to have a better grasp of mathematical concepts than present standards and sets higher expectations for teaching and learning.

If that doesn’t sound fuzzy, there’s a simple reason: It isn’t.

To appreciate the changes under way, and perhaps to understand the anxiety provoked by Common Core, it’s helpful to look at math before the core.

Too often, it has been “plug and chug” math. In this approach, math is a bunch ofmemorized rules that don’t make much sense. Follow the rules, and you will get the right answer. Do something different, and you’re likely to get it wrong. “Analyticalthinking” consists of figuring out which rule to apply. There is limited need for originality, explanations, or even genuine understanding. Learning enough rules will allow you to solve the problems you are given. Do this for enough years, and you may firmly believe that this is what mathematics actually is. If your kids are asked to do something different, you may be up in arms.

Reality of rules

Math as rules starts early. Kids learn in elementary school that you can “add a zero to multiply by ten.” And it’s true, 237 x 10 = 2370. Never mind why. But then when kids learn decimals, the rule fails: 2.37 x 10 is not 2.370. One approach is to simply add another rule. But that’s not the best way.

Common Core saves us from plug-and-chug. In fact, math is based on a collection of ideas that do make sense. The rules come from the ideas. Common Core asks students to learn math this way, with both computational fluency and understanding of the ideas.

Learning math this way leads to deeper understanding, obviates the need for endlessrule-memorizing and provides the intellectual flexibility to apply math in new situations, ones for which the rules need to be adapted. (It’s also a lot more fun.) Combiningcomputational fluency with understanding makes for problem solvers who can genuinely use their math. This is what businesses want and what is necessary to use math in a quantitative discipline.

Here is what good math learning produces: Students who can compute correctly and wisely, choosing the best way to do a given computation; students who can explain what they are doing when they solve a problem or use math to analyze a situation; and students who have the flexibility and understanding to find the best approach to a new problem.

Common Core promotes this. It systematically and coherently specifies the topics and connections needed for math to make sense, and promotes both understanding and accuracy.

No revolution

This doesn’t sound revolutionary because it’s not. Common Core is a list of topicseveryone knows we should teach. It doesn’t tell teachers how to teach them (though it does ask that they teach them coherently, with understanding). It is also not a test, not a curriculum, not a set of homework problems, not a federal mandate and not a teacher evaluation tool.

But you wouldn’t know it from some of the criticisms directed at it. It lays out the topics for students, grade by grade. The rest is up to the teachers, school districts and state boards.

The higher expectations laid out by the Core have been endorsed by every major mathematical society president, including the American Mathematical Society and theAmerican Statistical Association. They called the Common Core State Standards an “auspicious advance in mathematics education.”

Of course, the core will do best if parents can support their children in reaching these higher goals. Websites such as Khan Academy and Illustrative Mathematics have incorporated the standards and show best practices and well-crafted math problems.

There is no doubt that the new standards are more rigorous. They will require more of our students, our teachers and our parents. Knowing what you are doing, instead of just knowing a set of rules, is the essential foundation for applying math to the real world.

That’s not fuzzy. It is smart.

  1. Tara,

    Thank you for sending/posting this. It’s great to see what the kids are up to at school (and to see the pictures!).

    I read the article about Common Core and I agree with the points he states. Math should not be learned by rote, but understood. The problem I’ve found with Common Core, though, is the methods it incorporates. For the past few years my children have been using the Common Core curriculum I’ve noticed them understanding what they are doing even less than before. Instead of answering based on their understanding of the material, they are memorizing the steps to come to that answer.

    For example, take the problem 188+62=X. The old method was to line the number one on top of the other and solve it. The new method forces the student to find a number to round (Step 1), then to subtract the difference from the second number (Step 2), then add them together (Step 3). In theory, it’s much easier once they get the hang of it, but I don’t think they will. They’ve gone from memorizing one was to do math to another.

    I’m not an educator (at least not in a formal school setting), but my educational philosophy is to first do it – whatever “it” is – and do it right. The more times you continue to practice and exercise what you are doing the more you will unconsciously pick up new and easier ways to accomplish that same goal. Instead of allowing dynamic learning to take place organically in the student’s brain, Common Core is building static highways which (at this early stage) don’t make sense to them.

    I’ve heard many adults say that they never enjoyed math because of the way it was taught and Common Core is much more intuitive. Again, in theory it is. But as the late Yogi Berra said, “In theory there is no difference between practice and theory. In practice there is.” It *could* make math more enjoyable, but from my limited scientific sampling that theory has yet to be proven empirically.

    Just the other day I was helping Dina with her homework to solve for *n*. For the problem 4*n*+*n*=X. I was trying to help her understand what she’s looking for and describing what a variable is. She wasn’t interested and insisted that she knew what to do by copying what she was taught in class. She wasn’t wrong (her math was, just not her thinking to ignore me), but it was clear that she was less interested in understanding versus just getting it done. Again, this is only from my limited experience.

    Please don’t misconstrue this message to be a complaint on the school or its teachers, but on this curriculum. My kids are growing and learning beautifully and we couldn’t be happier with their teachers. I just hope that you seriously consider whether Common Core is a standard that was worth adopting or perhaps it would be better to revert back to “old ways”.

    All the best,

    • I always like hearing your take on things like this. I have always loved math, almost any way it was taught, but have seen students struggle with math more than any other subject during my 22 years of teaching elementary. I don’t think any system is perfect, and Go Math is no exception. That is why we have teachers to fill in or explain further, etc. I do know that as a nation we are struggling to have students graduate from high school with passing grades in ninth grade algebra. I think Common Core is an attempt to remedy this by starting students on it much earlier, and you are right, it remains to be seen how well it will work. We know what we have been doing is only working for a small percentage of the population.

      I am so glad that you are happy with your children’s education overall. We do take it very seriously. And to clarify, we haven’t “adopted” common core, all current curriculum is aligned with common core. We look at the standards, as well as what we know our students are capable of, and create our education from there. Our students are never limited by what the standard is for that grade, but we make sure that they are not below that standard. We have standards, without being completely standardized. That is such a blessing, as a private school, that we can use standards as a guideline, but we can also go beyond those basic standards to give our students so much more.
      Thank you for taking the time to read the article!
