Reader comments
This book feels very practical! It is compiled according to the textbook and is consistent with the teaching progress. It should be very helpful for children's mathematical calculations. Moreover, the questions in the book range from easy to difficult, and many calculation methods are summarized. I like this very much. However, I don't like the title of the book very much. It feels a bit childish and not very attractive. But overall, this is a good primary school mathematics teaching aid.
