I'm a retired math teacher, but still part of a school system. What our teachers are doing is distance-learning. Not the best solution - but it's better than doing nothing.
[1] Each teacher had to call all of her students and families to see who had access to technology and who did not.
[2] For students without access to technology, packets were made with work their students could do with parental help and mailed at the cost of the schools. . No, not all students have parental help. Packets were made for three weeks of daily work and in another three weeks, teachers will do the same thing.
[3] For those with technology, assignments were sent to be completed and returned to the teacher in a variety of technological ways.
[4] Our teachers are helping student via technology and zooming with students and home calls with parents. Our teachers are working just as hard as they normally do, plus having to teach their own children.
It's not ideal, but students [most] are excited to skype and zoom with teachers and are, for the most part, doing their assignments.
The only difficulty, obviously, is math. If a parent cannot add/subtract fractions, teaching the child will be impossible. And it's pretty much impossible to teach yourself how to multiply binomials. For science, social studies, reading, and English - lots of reading/writing assignments are given with videos to watch and research to do.
We made the decision to do this because we didn't want students to be so far behind when school comes back.
Some students ARE going to be behind, but teachers will making preparations to take the next year to pull them up.
We do not wish to go to school in the summer nor start on August 1. We want the students to have a normal of a summer as possible.
There are holes in the system, but it's the best we can do right now.
