The fourth graders learned how to improve their writing and make it more vibrant and descriptive.
"If you want your stories to live, they have to breathe," Johnson told the kids.
That means cutting out the "no-no" words, such as good, big and nice.
She told them to use stronger verbs, such as "strolled" instead of "walked."
As for the writing test, Cline said she thinks she'll get a good score.
"I've just always loved fun stories," she said.
One of her favorite authors as a child was Dr. Seuss.
"I loved the whimsical rhyming," Johnson said.
She chose to write children's books because she could make them as fun or as silly as she wanted.
