Limited writing ability

I am reviewing Thing 1's homework. There were several sentences with the words out of order, she had to figure out the correct order and write them out.

It reads;
“The cat sat down.
He had a nap.
A rat ran in.”

Then there were a couple of blank lines with the instruction to tell what happens next.

Thing 1 wrote:
“Dad Bams it.
I am sad of the rat.”
Her teacher fixed the “of” to a “for” and wrote a smiley and a YES! under her addition.
