Insurance can work. Most schools charge $25 a year and expect a certain breakage rate. However, the parents whose kids make through four years of school and nearly pay for a new Chromebook might not agree with the economics of insurance.
Soft covers are big and bulky. Kids dislike carrying yet another backpack. These are also pricey. Hard plastic covers are colorful and probably protect the devices once before breaking themselves. That's not terrible, unless, of course, students learn how to snap the plastic off the Chromebooks before they do something careless. Would that ever happen? All the time.
Cranium Chromebook Covers/Whiteboards by Educabana
Even if Jinks and Surfside's Dells come with expensive soft cases, the Cranium can help protect even more, like adding some caulk to the exterior paint. Kids break stuff at home and in school. Ask about bulk prices at Educabana if interested in Craniums. Ask about bulk prices for repairs if not. If you are a resident of Bay District Schools and want to make sure your half-cent sales tax is being protected, then ask.
