What to Teach
Core Knowledge Sequence - an outline of what children should learn at each age between kindergarten and 8th grade https://www.coreknowledge.org/our-approach/core-knowledge-sequence/
The eight-volume Core Knowledge Series—from What Your Preschooler Needs to Know through What Your Sixth Grader Needs to Know. This series gives a great outline for any nervous elementary homeschooling parent. If you only buy one thing to homeschool this year, I would recommend the book that fits your child’s grade.
