If there is only one activity you can do for home practice, it should be reading. According to Shichida, you should endeavour to read 5 books a day with your child. This recommendation is pretty similar to the recommendation from The Read Aloud Handbook by Jim Trelease:
Read three books a day to your child: one familiar book, one favourite book, and one new book. By the end of a year, you will have read 1000 books together.
Three or five, I think the important thing is that you read together and you do it frequently. Even if you child wants to read the same book over and over, that’s fine. The idea is to inculcate the love for reading so the experience should be fun and enjoyable. Instill the interest first – variety can always come later.
