Just as Teacher Zimmerman reached the last row.
She noticed.
These two little boys in the last row had their test papers laid out on the desk, already filled with answers.
Out of curiosity, she picked up the test papers to check them.
It was as if these two children had memorized the answers to the test, all the answers were, without exception, all correct!
Even though these were all addition and subtraction problems within ten, she could look at them at a glance and immediately write the answers.
But the thing is.
She is an adult, and the two little boys in front of her are only three or four years old!
Moreover, these two little boys had only spent around three minutes answering the questions.
Isn't this nearly the same speed as her own mental calculation as an adult!
