Talk with your boy about where they're at at school, what they've already studied this year, what else he thinks they're going to study at school this year, even if you already know. This will help set the stage for a sense of scale and timeline of how much work you're going to be doing at homeschool to make him more prepared when it's time to get started. Btdt as a kid.
