Great, let's make primary school a place to park children so their parents can go to work where children can do whatever the hell they want. These exist. They are called Sudbury or democratic schools.
While I have your attention, some links.
Teaching arithmetic to children below sixth grade has either no effect or negative effects, seeing as the extra education makes them worse at word problems.[0][1]
Homework has no positive effects on learning in any non-mathematical subjects and no positive effects whatsoever before middle school.[3]

DOI: 10.1037/a0022697 ABSTRACT Although homeschooling is growing in prevalence, its educational outcomes remain unclear. The present study compared the academic achievements of homeschooled children with children attending traditional public school. When the homeschooled group was divided into those who were taught from organized lesson plans (structured homeschoolers) and those who were not (unstructured homeschoolers), the data showed that structured homeschooled children achieved higher standardized scores compared with children attending public school. Exploratory analyses also suggest that the unstructured homeschoolers are achieving the lowest standardized scores across the 3 groups.
