This brag doesn't compare to other people's brags, but I paused to watch DS (7) play minecraft the other day. I NEVER watch this game, and don't really know what they do on there. I stood behind DS and watched as he constructed a ship. He was super fast, it was almost as if he wasn't doing it himself, but it was computergenerated in fast speed. The ship looked like a real ship, like something a graphic artist might do. I asked if he had built ships before, and he said no. He wasn't copying a picture. He said he watched a video about a ship, but that his ship wasn't the same (which I confirmed with DD who watches minecraft videos with him). Even if he was copying someone else's ship by memory, that's pretty impressive. I asked DD if she could do what DS just did and she said "No."
Considering his drawings done by hand look very preschooleresque because his DCD and fine motor issues, I thought this was very neat.

She also learned from the teacher that he thinks she is the strongest statistics student he has encountered in his teaching career (of a decade or more). He wants her permission to use her class project as an example for future students to show them "how to do it right."
I'm particularly impressed given that she did this with no direction from either us or from that teacher regarding the project the teacher has been more or less AWOL in terms of instructional support all year. My DD10 has shown some surprisingly advanced skill in writing patent claims (at Take Your Child to Work day last year). I think when you're around an adult who does it for a living, you can pick up quite a lot from "shop talk" and comments made around the house. Not to mention heredity from you, of course. Obviously neither statistics skill nor patent drafting are hereditary, but the underlying skills may be.

DS4 randomly decided to write a number pattern (he originally said he wanted to count by 1's, 2's, 3's, 4's, etc...which I thought meant he was just going to skipcount, starting back at the beginning each time he changed to a new increment)  but instead, it went like this:
1 2 3 4 6 8 10 12 15 18 21 24 28 32 36 40 45 50 55 60 66 72 78 84 91 98 105 112 120 128 136 144 153 162 171 180 190 200 210 220 231 242 253 264 276...
(in case you don't want to figure it out, it's four steps of each increment: counting by 1's four times, 2's four times, etc etc.) This alone was pretty cool, until he pointed out that he would end on a multiple of the next increment every time. (so at the end of the 5's he ends with a number divisible by 6 and so on and so forth.) The pattern doesn't stop. It took DH (super gifted in math) like 15 mins to figure out why. (if you are interested, it's because you end up with 4 x the successive triangle numbers, or 2n(n1). and if you need more explanation than that, you'll have to ask DH because honestly, it's all lost on me!) But yeah, it was just...kind of mindblowing that he was just able to toss that off.

Seriously cool! On the assumption your DH hasn't already explained it to DS, here's an attempt at an explanation that might make sense to your DS (I'm making the assumption that he spotted the pattern, which is impressive, rather than proving it always holds, which would be mindblowing). It'll be morally the same as what your DH did with triangle numbers, of course, but perhaps more approachable.
Write the numbers out in rows:
1 2 3 4 (row 1) 6 8 10 12 (row 2) 15 18 21 24 (row 3) etc., so that the row number is the number we're skipcounting by in that row.
What we're going to do is to show that the pattern continues for ever. We can see the pattern holds in row 1, and what we're going to do is to show that if it holds in any row, it holds in the next row as well. So row 1's pattern will force row 2's pattern to hold, and row 2's pattern will force row 3's pattern to hold, and so on as far as you like. (You may, but need not, tell him that this is called induction.)
But what exactly is it that holds in row 1? What matters is not just that 4 is divisible by 2. Actually, 4 is 2 x 1 (this row's number) x 2 (the next row's number). Let's say it like this: the last number in row 1 is the number of unit cubes that are in a cuboid with height 2, depth 1 and width 2. The pattern we're going to show holds is that the last number in any row, let's call it the nth row, is the number of unit cubes in a cuboid with height 2, depth n (this row's number), and width n+1 (the next row's number).
It might be a good idea at this point to build such a cuboid, say for n=3, e.g. in Lego.
Now, how much do we have to add to get from the last number in row n to the last number in row n+1? In row n+1 we're doing skip counting by n+1, so we have to add n+1, four times.
Imagine taking four n+1long bits of Lego (actually do it, and make them a different colour from the old cuboid, perhaps). Put them in a two by two by n+1 cuboid shape, and line it up with the width of the cuboid we built for the last number on row n, so that the two cuboids are stuck together on the 2 by n+1 face.
Look, we get a new cuboid, and the number of unit cubes in this must be the last number in the n+1th row, because we got it by doing a new row of skip counting starting from the last number in the nth row.
What are the dimensions of this cuboid? It's still got height 2, and it's still got width n+1, but now its depth is its old depth, which was n, plus the extra bit we just added, which has depth 2. So it's 2 by n+1 by n+2.
That proves that the last number in the n+1th row is divisible by n+2, so the pattern holds for another row.
Turn the cuboid round so that the n+2 length side (which is the depth at the moment) is the width, and we're ready to do exactly the same thing again for the next row... and we could keep doing this for ever!

Portia and Marnie, those are seriously exciting brags! Khombi, congrats to your DS. ColinsMum, can I keep you on retainer?
