This website not only has mathematics, but also science and English, covering all knowledge points from preschool, kindergarten and grade 1- 12.

There are 24 knowledge points in grade one mathematics, and there are various exercises under each knowledge point to help children understand the same knowledge point and the same concept from all angles.

For example, the knowledge point of F has seven sets of different types of exercises, so understand subtraction. When the mouse is gently placed on a specific point, a sample of this group of questions will be displayed.

Like the problem of small fish, it is clear to children to explain the concept of "subtraction" in the form of charts. In fact, this is also a sense of shape and number. Most of the exercises on this website are aimed at improving children's mathematical thinking, which is not our common sea tactics.

After the trumpet in front of the topic is turned on, there are pronunciation reading questions, and children brush math problems together and even learn English together.

If you don't understand the topic, you can click on the blue word "learning for example" above, which has particularly detailed solutions and explanations.

IXL is a very comprehensive website, covering all the contents that children need to master from preschool to senior three. It is a paid website, and you can use it without registering or logging in, but there is an upper limit on the number of times you can brush questions every day, and you can only brush 7 questions.

2. Khan Academy (free registration, from explanation to practice)

Everyone knows the famous Khan Academy, right? Even Bill Gates, who taught mathematics at the beginning, was its iron powder and true love powder. Mimi, my mother, specially wrote a guide to the use of Khan Academy to teach everyone how to make good use of this super baby.

The email address of Khan Academy can be registered and used for free. Mother Mi suggests that you test your child's concept of numbers first after registering and logging in. If this part is also zero, you'd better make up and use video to learn. Otherwise, the content and language are unfamiliar, and the effect is not good.

However, children in our country are all early in mathematics enlightenment, so they should be able to learn early mathematics when they are almost three or four years old.

3. Worksheet works (a large number of printable practice resources)

The pages of the worksheet can't be more concise. Besides math, there are other subjects such as English and geography.

Click to enter the math section, and the classification of knowledge points will be clear at a glance. From simple number concept to multi-digit operation, to fractions, decimal points, scientific counting methods, algebra and so on. Everything is easy and difficult.

Entering any knowledge point, there are very rich content categories.

Do you think this is over? This website is full of Russian dolls, layer by layer, and then click in, which is a set of exclusive exercises that can be customized by yourself.
