The child hasn't started reading yet. I have studied it recently. The pictures are very interesting and have strong hands-on ability, which is similar to the math progress of primary school students. It is no problem for kindergarten children to read them as picture books. Those concepts will have a very intuitive feeling through hands-on, which is much more vivid than the teacher standing in the classroom.

I did this to prepare my children. For example, now that I'm in the second semester of senior two, I'm going to learn division soon, so I'll let her read the book Divided by One in the winter vacation.
