First: train attention. Ruta numbers are boring because they are meaningless, irregular and irrelevant. Therefore, if you want to recite it, you must concentrate. The more numbers, the longer it takes to recite, and the longer it takes to concentrate!

Second: develop the hemisphere and the right hemisphere. Because memory pi needs to use digital images for associative memory, children's thinking ability, imagination and creativity of images have also been developed in this process!

Thirdly, pi can be used as "human brain gymnastics" to train mechanical memory and activate brain cells. According to Darwin's "Origin of Species" principle, memory pi can stimulate brain cells and stimulate thinking!

Fourthly, pi can be used as an effective training method for word memory, chain memory and other memory methods. At the same time, reviewing the digital object-image conversion code will help children quickly master a set of methods to remember numbers, make them more sensitive to numbers, and thus stimulate their interest in numbers, mathematics and quantity!
