Our letter mentioned they would give a space in classroom to give mask break… How beneficial is it to give kids 2 masks, one for the morning, one for the afternoon?

It is commonly stated that a rough estimate for the maximum amount of time that a mask should be worn is 8 hours. Re-use of masks is not recommended. As such, if the mask is removed, it could be beneficial to provide a mask for the student to change into part way through the day. For more recommendations on mask use, please see the World Health Organization’s Advice on the use of masks in the context of COVID-19, seen here
