My kid is still very young and still learning the very basics of reading/writing/arithmetic. So we reinforce/practice those at home. I've found that his motivation is higher when the stuff he learns at home matches the things he learning at school. We also do a bunch of weekend activities with an educational aspect - from external events like Maker Fair and Science Expos, to taking apart the lawn mower to learn about engines. We also have this fun ritual at bedtime where he can ask any question about anything and get a serious answer. Of course this is used to delay lights-out but it's one of the most valuable learning exercises (for parents too). At this age, almost everything can be made educational but the trick is to keep it fun.
