26-7 calculation method. There are many ways to calculate this problem: for example, adding ten, decomposing, breaking ten and abdicating, etc. The actual breaking method and decomposition method are the same.

Students can use the method of breaking ten to calculate: 26-7, first break the minuend into 10 and 16, then subtract 7 from the broken 10, which is equal to 3, and finally add 3 to the broken 16. 16 shisaner 19. This is one of the methods of 26-7.

Mathematics learning skills in large classes

The understanding and composition of numbers within 10 should be related to different forms of "numbers" in various forms, such as "points". By encouraging children to tell stories to understand the composition of numbers, children are advised to know more about numbers and shapes, observe more, operate more, think more and remember less in life. The principle is to keep children curious and enjoy math, rather than have a sense of disgust.

The best way to recognize graphics is building block games. By touching, conceiving and building, the characteristics of objects with different shapes are inspired, which is also an exercise of spatial thinking. Combining life, entertaining and playing middle school is the correct way to learn.
