Information Is BeautifulQuick! What's 6 x 8? 7 x 6? The trickiest multiplications for kids aged 5-8. How many do you still struggle with?
Campbell Jones@infobeautiful 6×8 is 48, 7×6 is one that admittedly took me a few seconds...
Michael WestergaardThe best part is it’s not 100% symmetrical along the diagonal
kasperdI noticed that as well and think that’s an interesting result. The asymmetry tells us something about how kids learn to multiply, though I am not sure what that something is.
Multiplication of small numbers is pure memorization. So this tells us they learn one ordering more than the other.
I know I remember 6 * 8 = 48 as "both end in 8." That rule doesn't work for 8 * 6, making that a harder operation.
the roamer@kasperd @infobeautiful @michael
They "do the eights" and they "do the twelves", and these are distinct operations. Both are interrelated since 8x12 = 12x8, but swapping the order of the operation is a huge mental step that is costly to execute. So they stick with one and then make mistakes if multiplication in that order is more error-prone.
In a sense the students' seemingly limited behaviour reflects deeper mathematical truths. Multiplication need not be commutative, in many algebraic systems it is not, and here we see the students acting in a way that pays due respect to the fact that we must not take commutativity for granted! :-)

It is unclear in which order the coefficients were assigned (since the table is not symmetrical) and the 1x1 legend does not really help here :)

Mono@infobeautiful The most evil thing about this chart to me is that it's not symmetrical
Heckin' Chonker@infobeautiful Is this suggesting that 10% of kids get 1x1 incorrect?
Rickyx@infobeautiful to master 7x8 you can reverse the whole equation:
56=7x8.
For my children it is easy to remember 5678 and now, no problem!

𝐽𝑜ℎ𝑎𝑛Very strange. In which schools is it in which country? The multiplication table is usually learned at the age of 8-9, isn't it?
Æ Sea F.@johan @infobeautiful The infographics says 232 children were studied at Caddington School, possibly the one in the suburbs of London.
Звучит как титры для хоррора:
180 детей сошли с ума...
50 были отправлены в исправительные учреждения...
Двоих, брата и сестру, так и не смогли найти.
В 2012 здание было продано под склад Озон, пока...
Там не начали таинственно пропадать таджики...
