Making education entertaining
The books increase in difficulty as readers progress, applying theories of childhood linguistic development. The first set of books focuses on things like words for parts of the body, numbers, family life, interacting with nature, greeting elders, having breakfast at home, mom cooking eggs in the kitchen, and going to play in the park. The second set helps children build longer sentences, developing their language skills through repeated sentence structures and the use of onomatopoeia, and the third set is suitable for children from the age of five to second grade. As the books progress, they not only increase in vocabulary difficulty, but also in the amount of cultural context and awareness involved, for example, talking about Indonesian cakes made with pandan leaves, games played in Southeast Asia, and so on.
The design of these teaching materials incorporates many ingenious touches, such as the addition of a number of small games. For example, parents can do role-plays with their kids, pretending to be rabbits, birds, and butterflies, or they can use everyday household items like laundry baskets and bath towels to play games with the children.
