My son (1st grade) who stumbled on the National Unified Elementary School Test

"I might get a good score in math!"
On the morning of the National Unified Elementary School Test, my son, who is already at a 4th-grade level in Kumon math, was full of confidence.

...but his first words when he came home from the test were,
"I didn't have enough time to finish the math section. But I did my best."

Seeing my son with his shoulders slumped, my heart ached a little too.

When we checked his answers at home, he probably got around 90 out of 150 points.
It looks like a result below average.
(Though this is just a 1st grader's self-grading, so I'm not sure.)

"Does that mean I'm below average?" my son asked, feeling dejected.

But I told him this:
"The reason you didn't get a good score is on me, the one teaching you.
Besides, finding out what you're weak at is actually a good thing.
Now we can work on it and turn those weaknesses into strengths.
It's a good thing we found out now."

I feel like this was a good lesson for my son, who had been getting a bit cocky lately because he could do some calculations.

That said, if we leave the problems he stumbled on as they are,
studying might change from being "fun" to being "painful."

From here on, it's my turn as a parent to step up.
First, I will urgently look for a "fun way to review" the problems he got wrong.

I'll probably end up preparing some concrete objects to help.
