I happen to pass by my kid's room and heard her shout "hooray" while some of her classmates, "hep hep". I peeped. She's having her online classes. It's their second year of having classes online because of this pandemic. After classes, I asked what was that about. She answered that it was their teacher's way of checking the attendance while making sure everyone is focused and attentive to their online class. I thought it was very creative. Online classes do have its challenges, not only to the students but to the teachers as well.
