Sweet little 7 year old Abi, the light of my life came home from school with week with her homework...
Long division
jesus wept I've not done that since I was 7. I showed her how to do it using an easier method ... to which she sat arms folded with a cross face. "that's the 'garage' method, I need to do the long method". It turns out there's loads of ways of doing it now: chunking, long, garage, partitioning ... more genres that nu metal. Thank God for Google.
Bring back these, that's what I say ...

Is that some kind of hurdy-gurdy, folky thing?

The method she is using is, for example, if you're dividing 296 by 7, first you work out the multiples of
1 x 7
2 x 7
5 x 7
10 x 7
20 x 70 then subtract it from the 296 in stages and add up the factors you used (ie 1 x, 5x, 20 x).

Most schools now teach multiple methods because it allows the child to understand the maths rather than just follow the process. As a minimum it lets them select the method that works best for them. It isn't the same for everyone. I now tend to use 2 methods to check my answer on longer sums.
Its a different focus to just teaching you a method which you forget as soon as you leave the classroom. A lot of the old school ways are all about remembering an easy method rather than the functions behind it. if you trust your method it can make it hard to spot mistakes
Chunking is a bit long winded, but its great for emphasising the links between multiplication and division

There are new methods now, some of which look unhelpful to me, but I'm not your typical student
Often the kids have been set homework including topics they have not yet covered in class (so they tell me), and I cna end up tellinhg them stuff from too advanced a perspective
Ibought this book, but probably need to read it:

for younger kids there's this:

I'd have thought that long division and using log tables are not really much use now. Maths should all be about understanding the way numbers work, rather than learning how to do error-prone manual calculations that have no use in real life
