In the 5th grade, the students are learning how to write checks and balance a checkbook. They've got a replica checkbook to do the work. In his imaginary bank account as assigned by his math teacher, JT has $5,000.
This, of course, makes me want to enroll in the 5th grade. Because God knows I've never had $5,000 in my checking account. I guess that I should have gone to prep school.
