Good online resources for free educational materials (all of these respect students data and don't sell it, which is a legal requirement in my state):
EdPuzzle- videos with embedded questions about the material covered, ~1st-12th grade
CommonLit- online texts on just about any topic with embedded questions and optional videos as well as links to related texts, 3rd-12th
ActivelyLearn: online texts for all core subjects except math, include videos, definitions, gifs, questions, and polls to make the text more interactive, 3rd-12th
Prodigy Game- math game that's set up like Pokemon so kids love playing it (seriously, search it on YouTube kids are getting 100ks of views on streaming videos of this game), covers common core standards, pre-assesses the kids levels and then moves them up or down in skills as needed, 1st-8th
PhET- really cool interactive science and math simulations so kids can use manipulatives online or even run lab experiments without having a science lab available, 1st-12th grade
Resources for You:
I loved this Coursera course from the University of Minnesota on resiliency in children who have faced trauma (it mentions war in the title, but they also address more common traumas we see here like neglect, community violence, poverty, and abuse):
