So that your child does not perceive learning as a nuisance, the learning phases should rather be more frequent, but shorter, than the other way around. Sometimes just 5 minutes a day is enough, for example, to practice multiplication tables or go over some vocabulary. And your child doesn’t even have to pick up his or her textbooks, because learning can be done virtually on the side. -For example, when you are shopping, adding up the goods, measuring something while doing handicrafts, or your child is reading an interesting newspaper article whose (political or historical) background you explain to him or her.
This is also a good way to establish a routine. Learning is thus integrated into everyday life outside of school. At best, you don’t even need to remind your child, because he or she will want to learn more on their own!
