Agnes is about ten…. fourth or fifth grade.
Not sure about 2019, but I remember working with fourth grade students on division by a single digit number back in the 1970’s.
Before they learn decimals, if the result isn’t even, they say the answer is “2 with a remainder of 4.”
Then they progress to saying 2 and 4/7ths (2 and four sevenths… hard to read here) without having to divide out the fraction.
Eventually they get to 2.57, R=1, then probably in what is now called upper middle school, 2.5714, or however far they’re supposed to take it.
They’ve also learned to divide by two digit numbers somewhere along the way.
With “Common Core” math and its emphasis on methodology over accuracy, they’re probably allowed to say “a little over 2 and a half”, now, if they can explain why.
