For anyone who's caring for school-age children, I want to let you know that nearly every single online education platform/tool is currently offering up their normally premium paid services for free on account of school closures. While some will offer these directly to parents/students, most of them require a teacher to sign up and then have the student account exist underneath them.

If there is a resource that you or your children would like to access, please email your child's teacher and ask if they'll sign up for it. It'll likely take only two minutes on their end (and they'll be happy to do it! trust me!), but it'll open up a ton of resources for you and your child.

Ok I'll start:

Brazil: here the schools are split between the fundamental level, which is 1-9th grade, which is then subdivided onto fundamental I and II, which range from 1-5th (ages 6-11) and 6-9th grades (ages 11-15) respectively. Then we have 'medium' level ("Ensino Médio") which goes from 10th-12th grade, and then we have a national test called ENEM, where everyone takes a test to be able to enroll in the many colleges/universities which accept it, where you then reach 'superior' class and take technical courses and the like.

Class goes from 7-12:20 Am for fundamental II and 1-5:20 pm for fundamental I. This is because each day is divided into six periods of 50 minutes (+a 20 minute break, like in most places) for the sake of making subject distribution easier.

There are 8 subjects in fundamental class, Portuguese (grammar), math, geography, history, science, physical education, English (still mostly grammar) and arts. (Unsurprisingly it's more about culture & music than how to draw)
In 'medium' class, 3 more subjects are added, which are biology, physics and chemistry.

Funding for education is reserved for the states to decide, although it usually goes from 15-25% of total tax revenue.
