A high school history and economics teacher in eastern Idaho is selling advertising space to a Pocatello pizzeria on his student handouts, tests and worksheets.

High School teacher Jeb Harrison says he wanted to save money and teach kids about advertising.

The school recently cut back on paper allowances for teachers to prevent shortages. Harrison says he approached Molto Caldo Pizzeria about two weeks ago and now he has enough paper to last through the next school year.

Pizzeria owner Dan McIsaac bought about $315 in paper and paid to print advertisements on the pages.

At the bottom of an economics test in Harrison's class, students are now reminded they can buy a 14-inch pizza for $5.
