“I teach Spanish to PK through 5th grade. It's crucial that the "littles," especially, see my mouth as they learn new words. I wear this shield in my school with PK and Kindergarten students during our classes (They wear masks). It's not 100%, of course, but I think it helps me do my job in a way that works and keeps my own health (and theirs) at an acceptable risk (God help us, I pray so!). Thank you for a great design!!”
