This is a set of books on mathematics enlightenment, but it is not to teach children to add and subtract, but to infiltrate some mathematical concepts through stories and guide children to think and summarize. This story is very interesting. Children will be attracted by stories similar to solving crimes. You can watch it when you are about 3 and a half years old, and you will like it when you are over 5 years old.

It doesn't matter if you make a mistake: it doesn't matter if the milk is spilled, you can clean it up at any time; It doesn't matter if you try different directions, you may find something new; It doesn't matter if you don't know the answer, asking questions helps you learn; It doesn't matter if you are in a bad mood, friends will encourage you; It doesn't matter if you fall, you can always get up; It doesn't matter if you wear two different socks, others may try.

I always say that children are not afraid of making mistakes when they grow up. The mistake lies in the right path. Only when something is done wrong can they know how to do it right.

These books are very good. You can show them to your children. As for toys and the like, children of this age prefer Lego bricks, magnetic films and this kind of assembled building blocks. It is easier to exercise children's hands-on ability and imagination. In addition, such as magic ruler, imitation, jigsaw puzzle, etc. can be used. If you like to disassemble things, it is also good to prepare a set of playing tools for children to disassemble and disassemble themselves.
