These go on sale often and you should absolutely get one for your classroom. I just upgraded my home one and moved the old echo to my school. I love that I can enter my room and ask echo to play my playlist, podcast, or news while I prepare for the day. If students are working on silent work a classical music playlist is a voice command away. My favorite use of the dot is setting timers. We all know that students think time to work on assignments is endless. If you can't put up a timer on classroom screen, or just need a quick 45-second one or so while you students are pair-sharing and you are walking around, echo dot is your best friend. Students tend to get to work when they know your 1 minute actually means 1 minute and not whenever you are done with x,y, or x. Also, students are curious by nature and I do not know EVERYTHING there is to know about science, shocking I know, but you can always ask echo about those facts you don't know or care to store in your brain. Be aware that not all schools allow these, but if you have open BYOT it should work fine.
