This set of books is divided into 8 volumes, which are scientifically divided according to the age and ability of children aged 3-6, and studied step by step. It is entertaining and rich in content, from the recognition of graphics and the face value of money to the addition and subtraction of one-digit and two-digit numbers. It is a well-deserved partner of children's mathematics enlightenment, helping children to establish mathematical concepts at an early stage and lay a good foundation, so that children can easily face primary school mathematics.

The textbook Moby loves mathematics is aimed at children aged 3-6. According to children's natural characteristics, after ten years of teaching results, it is completely tailored for domestic children (although Singaporean mathematics is good, I am afraid it will be a little acclimatized to come to China, but Moby doesn't have to worry about this problem if he loves mathematics), and it has become the mathematics "Bible" in the minds of many parents.
