Hundreds of school systems around the country have adopted four-day weeks in recent years, mostly in rural and western parts of the U.S. Districts cite cost savings and advantages for teacher recruitment.

It’s a Monday in September, but with schools closed, the three children in the Pruente household have nowhere to be. Callahan, 13, contorts herself into a backbend as 7-year-old Hudson fiddles with a balloon and 10-year-old Keegan plays the piano.

Like a growing number of students around the U.S, the Pruente children are on a four-day school schedule, a change instituted this fall by their district in Independence, Missouri.

To the kids, it’s terrific. “I have a three-day break of school!” exclaimed Hudson.

But their mom, Brandi Pruente, who teaches French in a neighboring district in suburban Kansas City, is frustrated to find herself hunting for activities to keep her kids entertained and off electronics while she works five days a week.
