My son is in year 4 and has a weekly maths quiz, which he and I both like - it's good reinforcement. But it's always oral, and he sometimes says he's been confused by the question for not having seen it in writing or he'll maintain that he answered the question correctly and is upset that he's missed it. The quizzes don't come home, per school policy (they want to avoid having to re-write them every year).
I certainly don't think that the teacher is reading out the questions incorrectly, but rather that this is a good reason to avoid oral math quizzes.
Is there some virtue of oral exams that I'm overlooking? Is this unusual in year 4?
My son is not struggling in maths, doing well, no other issues.
Thanks.
