one of my students mothers' gave me this and I have no idea what I am looking at
They are 7
So they explained that in the first table there is 40 between 3 people
so 10, 10, 10, 10 -> 30, 10 left from 40
2 2 2 2 -> 30+2+2+2, 4 left from 40
1 1 1 1 -> 36+1+1+1 1 left from 40
Then the child shows me the second set of tables and says "teacher says 50"
...what?
