Ask Slashdot: Math-Related Present For a Bright 10-Year-Old? 238

peetm writes: I have an above averagely bright nephew, aged 10, who's into maths and whose birthday is coming up soon. I'd like to get him a suitable present – most likely one that's mathematically centred. At Christmas we sat together while I helped him build a few very simple Python programs that 'animated' some simple but interesting maths, e.g., we built a factorial function, investigated the Collatz conjecture (3n + 1 problem) and talked about, but didn't implement Eratosthenes' Sieve – one step too far for him at the moment perhaps. I've looked about for books that might blend computing + maths, but haven't really found anything appropriate for a 10-year-old. I should be indebted to anyone who might suggest either a suitable maths book, or one that brings in some facet of computing. Or, if not a book, then some other present that might pique his interest.

    haven't really found anything appropriate for a 10-year-old.

    Don't buy something appropriate for a 10 year old. Buy something appropriate for a 15 year old, and let him grow into it as opposed to him growing out of it.

    • Agree... Something for a 10-15 year old. I would try an antique graphing / programmable calculator. You get math, graphs, rudimentary programming, and that antique cool factor.

      Couple of things to look for products that might be appropriate...

      The metric system was built to allow simple conversions, with 1:1 relationships between energy, mass, volume, temperature, etc. Something like that could be handy as it explains those relationships if it plays with them.

      For me, physics-through-calculus was a lot better than physics as taught by the high school physics program. Specifically we learned how distance, velocity, and acceleration are derivatives. This is a real-world appli
      • This is a real-world application for the math, and being able to see how the math actually does something in real life makes it a lot more fun to learn it.

        I couldn't agree more. This is why I did much better in physics than I did in math, where a lot of the algebra was the same. Plugging in real-world values into the formulas and working them out was much more exciting to me because I was dealing with values relating to actual real-world things.

Being able to start to organize mathematical calculations for the likes of area of a circle and volume of a sphere or cube and carry out those calculations are well within the ability of a 10 year old who is interested.

  • Some thoughts:

    Ultimately, maths, despite its abstract nature, is a human endeavour practised by humans. Humans have emotions. They like fun, joy, beauty etc. and dislike boredom. Once somebody dislikes maths, forcing them to learn can make them dislike it a lot, and quickly. Thus the fun and joy part are of critical importance. Knowing the territory where the child is exploring, and being able to guide them gently, but let them explore, is important.

    There are a bunch of good Martin Gardner books to consider. A couple of possibilities are:

    • "Entertaining Mathematical Puzzles" has a great range of puzzles across a range of topics
    • "Codes, Ciphers and Secret Writing" though not explicitly about math, has lots of good engaging content. Kids of that age often love codes.
    • Various "Aha" /"Gotcha" series ones
    • various logic puzzle ones

    These are generally good in that they encourage mathematical thinking and analysis and don't rely much on prerequisite material. And they are well done, with a good playful attitude about things. And they are often Dover books and reasonably priced, as well!

  • The Art of Problem Solving [] is an online self-teaching maths website with a really strong focus on curriculum quality. So if the kid likes maths, you can let them learn more of it!

  • Get him Ivan Niven's The Mathematics of Choice (How to Count Without Counting). Most computer nerds never heard of this one, and may not get the relevance, but I think it is totally appropriate for young teens. I read it in high school when I was 14 or 15. And yes, this is the best recommendation you will receive today. It's a basic, extremely well-written combinatorics book, so you can read the book yourself and create interesting programming problems for him for reinforcement. Don't deny your nephew
  • Just a suggestion that you might want to widen your horizon a bit. Most of what you've been doing is related to number theory. You might consider topology (mobius strips), geometry (compass and ruler), real numbers (show pi is irrational), platonic solids (wikipedia has some you can print, cut out, and fold), zeno's paradoxes (there a many), probability (die rolls and coin tosses), and almost any basic physics demonstration.

At 10, this might be nearing the edge of being too simple, but it's a book about prime numbers, factors, multiplication, sets, etc., presented with the numbers as monsters, with multiple visual depictions of how to imagine the numbers. For instance, the 6-monster is a combination of the 2-monster and the 3-monster, visually demonstrating that 6 is a combination of 3 and 2, whereas every prime number monster is visually distinct.
