Draft plan for re-opening MCPS schools: montgomeryschoolsmd.org/reopening/MCPS…. Highlights (thread):

* School will start Monday, Aug 31 with reduced class size
* MCPS will be virtual-only to start the year given current conditions * Students will return on a rotational schedule by grade level, last name/address (see Phase 1-Phase 3 below)
* Once your grade is allowed to be in-school, they will follow a weekly rotation of 2 days in-person, 2 days at-home (high school schedule looks 😨)

When schools re-open, how about high schools starting an hour later? I've heard so many parents saying the extra sleep has been so helpful for their teens. /1 cdc.gov/features/schoo…

United States was formed through pillaging ($1 million worth of tea into the Boston Harbor) which sparked the American Revolutionary War. In 1776, the Declaration of Independence was signed which read "that all men are created equal..." /1 ...that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness."

But those rights, that life, and that liberty was for the white straight man and the rest of us have been fighting for it ever since. /2
