A teacher is facing disciplinary action after she made pupils pay to go to the bathroom.
The teacher said she wanted to teach the children the value of money by introducing a "pay to potty" policy, but that led to at least two of the young pupils wetting themselves.
The children had to earn Monopoly money that they could then spend on buying toys, popcorn, pizza or going to the toilet.
Merchon Ortega, whose daughter Lilliana had a little accident in her classroom, said, "What kid is going to spend money to go to the bathroom?
"Not child should have to pay to use the restroom. Are you kidding me? That's absolutely insane."
The incident happened at Mill Plain Elementary School in Vancouver, Washington, and officials are now looking into what happened.
The teacher is not taking the class while the investigation continues, school district spokesman Gail Spolar said, and a substitute teacher is working there for now.
She said,"We're never going to prevent a child who is in an emergency situation from going to the bathroom.
"We don't want the children to have accidents. We don't want the children to have health and safety issues and so that's part of that investigation is how the procedure is being done."
