There aren't any 8th grade government classes. That's a jugh part of the problem.
Actually in my day (1960’s) we learned this stuff in 6th & 7th grade history class. By the 8th grade we had to memorize the bill of rights and be able to explain it in detail. I only had one daughter that learned about this in grade school. They skipped it entirely with my other two children. Fortunately, my children learned about the constitution and bill of rights from their parents and grandparents.
