A group of California teenagers came up with an entertaining way to educate kids about the basics of the coronavirus. For their final project in their economics class at Long Beach Polytechnic High, 15-year-old freshmen Lauryn Hong, Ella Matlock, Sofia Migliazza and Erin Rogers created a business plan for a coronavirus-themed coloring book. Then, with the requirements of the assignment fulfilled and at the encouragement of their teachers, they put what was supposed to be a theoretical plan to good use. The group’s new Be The Change Coloring Co. expected to sell 25 coloring books, primarily to family and friends. But in the first month, the girls sold roughly 500 copies and raised more than $1,000 for various charities, including several focused on coronavirus relief.
