There are simply too many official series, and each topic can give you a series, each of which is still very thick. If children are interested in a particular topic, they can buy it specially to make it enjoyable.

For example, when we were young, we were obsessed with connection. At first, we didn't find the official document format, so we had to print it out specially. If you have children who are obsessed with connecting, you must use the official document format, and you must count from 1 to 100 after you finish.

Logic dog

Logic dog is a set of teaching materials introduced earlier, which is very classic. Different ages correspond to different topics, and you can graduate from early childhood to primary school.

When some mothers heard about math exercise books, their first reaction was "Wow, the children are so tired, and they are going to brush the questions at such a young age!"

Actually, it's not that exaggerated. Proper use is very helpful for children's growth.

A good math workbook is not the kind of teaching arithmetic and brushing problems that many mothers understand. Today's workbooks focus on playing with middle school and help children improve their logical ability unconsciously through interesting questions.

In fact, logic plays a very important role in mathematics, which may not be seen in the lower grades, but once it comes to the category of Olympiad, logic is everywhere. The relationship between children's brain development and age, the horizontal axis refers to age, and the vertical axis refers to brain capacity. Basically, 0~6 years old is a period of rapid growth of children's brain development, and after 6 years old, brain development will be very slow! This is why many series of math workbooks on the market now have 2+ options.

Another advantage of exercise books is to kill time. For example, many exercise books, official documents, Qitian Town and so on, which are mainly based on enlightenment, are very popular with children. When Yuanbao was more than 2 years old, he especially liked to connect with the internet for a while, and the books he bought were quickly finished. No problem at all from 1-20!
