Makes sense to me. Kids aren't learning if there's an outbreak causing half of them to call off for a week. I'm sure rightwing partisans will roll their eyes but would you rather do everything in our power to mitigate the spread and otherwise go to school as normal or would you rather we have to start the home schooling shit again when a good chunk of the population falls ill at once?

An ounce of prevention can pay off with significant benefits and avoid a much worse outcome.

To anyone who would say "masks don't work at all," get away from your facebook memes and look up some actual peer-reviewed studies on the topic. We aren't doing this for fun; it makes a difference. For example, we saw a significant reduction in flu cases during all the Covid restrictions; there's data that virus concentrations are reduced (no, flu is not covid, but we have decades of data and trends to analyze there).
