Teaching Calculus To 5-Year-Olds

Doofus writes "The Atlantic has an interesting story about opening up what we routinely consider 'advanced' areas of mathematics to younger learners. The goals here are to use complex but easy tasks as introductions to more advanced topics in math, rather than the standard, sequential process of counting, arithmetic, sets, geometry, then eventually algebra and finally calculus. Quoting: 'Examples of activities that fall into the "simple but hard" quadrant: Building a trench with a spoon (a military punishment that involves many small, repetitive tasks, akin to doing 100 two-digit addition problems on a typical worksheet, as Droujkova points out), or memorizing multiplication tables as individual facts rather than patterns. Far better, she says, to start by creating rich and social mathematical experiences that are complex (allowing them to be taken in many different directions) yet easy (making them conducive to immediate play). Activities that fall into this quadrant: building a house with LEGO blocks, doing origami or snowflake cut-outs, or using a pretend "function box" that transforms objects (and can also be used in combination with a second machine to compose functions, or backwards to invert a function, and so on).' I plan to get my children learning the 'advanced' topics as soon as possible. How about you?"

      How exactly does this equate to the GP having a problem with English? You're talking two different opinions. You are suggesting that the difficulty of any task should have an objective rating, and the GP is suggesting that the difficulty of any task is subjective. You attempted to prove objectivity by using subjective difficulty of a child performing the task in relation to the subjective difficulty of the GP, do you see the gap in logic there? Not only are you using subjective means to prove a point of objective rating, but you're drifting into ad hominem using a child implying that the task is trivial. You aren't doing anyone any good here. If you wanted to make your point, you should have used a collection of subjective data to form a median or average objective rating, and leave the ad hominem attack out completely.

We were making little check-boxes and guesses. Their method for long division was absolutely horrible for large numbers, and working ONE long division problem took half an hour.

      I the traditional private school I learned long division using the classic decimal place subtraction method where you gradually accumulate your result at the top of the paper and get a long train of carefully prescribed subtractions trailing down the page. Much, much better. Homework might involve 5 long division problems that could be worked in 15 minutes if you were good.

    Teaching Calculus to five year olds is stupid. But that's not really what the article describes. I think a critical distinction implied by the article but not stated is that there's a difference between rigorously teaching a topic to the point of mastery, and exposing children to a topic to make them familiar and comfortable with it.

    I've always believed that 50% of time in school should be spent rigorous teaching, and 50% of the time should be spent easing students into more complex topics over time. I think its not productive that a student is not exposed in any way to a topic like statistics, say, and then suddenly they land in the class and have to learn the topic from scratch starting with little or no familiarity with the topic at all. I think the article suggests that rather than spend all of your time practicing arithmetic, it would be more beneficial long-term to start introducing complex topics at a level where the students aren't being asked to demonstrate complete mastery. You aren't going to give a five year old calculus homework. But a five year old exposed to mirror books, say, becomes a seven year old that is familiar with the concept of iteration and can be introduced to the notion of infinite series. That seven year old becomes a ten year old that is comfortable with the concept of summation, even if they aren't masters of the formulas. But when geometry comes along at thirteen, they would be a lot more comfortable with construction, with algorithms, with geometric limits.

    Basically, these days most schools teach single-point classes. What you learn in this class has little to do with the next class. Learning geometry doesn't help you learn probability, and neither help you much in learning calculus. Its all learn today, forget tomorrow, dive into the deep end of the pool for the next topic next year. But subjects like algebra and calculus and statistics are based on concepts and ways of thinking that are not intuitive or trivial for most people. Taking the long view, and investing time today to make it easier to learn those topics tomorrow is I think what the article is really talking about, and its a notion I happen to agree with 100%.

    You can take this to silly levels. Actually trying to teach calculus to a five year old, or even a ten year old, is ludicrous. 1% might get it, the other 99% will just get confused or frustrated, or worse oversimplify to the point of error just to pass the class and then face even worse hardship when they have to learn it "for real."

Point is, it was pretty obvious that none of us had used that part of algebra II in the years since we were taught it, whereas calculus was something we all felt much more comfortable applying, despite the fact that it's supposed to be harder.

  47. Cognition by Anonymous Coward · · Score: 0

    A five year old is not a fully developed adult. They lack certain cognitive abilities in general, such as an understanding of the lingual construct of the passive voice. You are usually doing well if the child at that age understands the concept of whole numbers (0, 1, 2, 3, 4, etc) and limited rational real numbers.

    I strongly doubt that children at that age can generally understand a limit problem or the idea that numbers are infinitely divisible. In basic calculus, you are calculating the area under a curve by adding up an infinite number of zero-width trapezoids and coming up with a number that may be negative.

    My father taught 5th grade. In the late 60s, in this school, that was when they worked mainly on word problems. My father decided to teach them all (not just gifted students) basic algebra having to do with subtraction, addition, multiplication and division in order to solve these word problems. He presented it as playing games with the numbers. There were several interesting results with his experiment. First, most of the 5th graders quickly grasped the concepts when presented this way. Second, the students began solving these word problems more quickly and more accurately as compared with classes of previous years. Third, the students enjoyed the insights. Fourth, the concepts seem to help the "slowest" students the most. Fifth, creative teaching, regardless of its success, was frowned upon by the school administrators and he was forced to stop the program.

  54. As a maths teacher.... by Anonymous Coward · · Score: 1

    Calculus is a topic that is taught very badly in High School. Too many "teachers" make it hard - they believe it's hard to teach, so it becomes hard to learn. I've seen a trainee teacher stressing out at the term "limiting slope of the secant" because "I've never learned about secants". In my experience (only 30 years), calculus is easy to teach, and easy to learn, as long as you leave formal treatments of limits 'till later. The formal statement of the meaning of a limit is a scary sentence to most students, so let them get a good intuitive feel for what it means first, let them get the "rate of change" and "slope of the tangent" ideas firmly consolidated, then the formalisation makes sense.

    Abstract algebra is another one that most teachers shy away from. I've taught it to 11 year olds though, by simply using something they should be familiar, the good old analogue clock, where 12 is a zero, and 3 times 4 makes zero. It really opens their minds to realise there are ways of looking at number that break the mold they've been used to. There is no need to make a beautiful, elegant and logical subject hard, regardless of how "advanced" it is.
