Visualisation of which parts of the multiplication table 5-8 year old students found the most difficult

Reddit:

I found it interesting that the chart is asymmetrical… They should be the same though I guess at the age where you are learning times tables you wouldn’t really grasp the symmetry of mathematical operators

That’s the first thing I noticed too. But then again when I was taught multiplication, we learned the numbers in order: our “4s” then our “5s” etc. I imagine that’s the issue. seeing 4×8 you think of your 4s, seeing 8×4 you think of your 8s and don’t know those as well. And like you said. We know they’re the same now, but we didn’t when we were 8, I think.
