Mathematics corner activity has teaching attributes, but compared with collective teaching activities, it is independent, decentralized, more free and self-centered, which requires teachers to respect children while guiding, and can not let themselves go. Mathematical corner activities usually materialize mathematical goals into hierarchical and diversified materials, and infiltrate mathematical core experience into operational activities. In math corner activities, children can choose independently and operate independently according to their own ability level, while teachers should pay attention to observation. On the basis of understanding children's mathematical experience and operation level, indirect guidance is the main way to promote children's independent development.

District corner activities provide children with sufficient exploration space because they can choose freely and operate independently. Therefore, teachers should not rush to ask children to achieve a certain activity goal, or get involved in children's activities too early, but they should not stand by and let children do whatever they want. The teacher should accompany them and pay attention to observation. The teacher's company can create a safe environment for children and provide strong psychological support. Teachers should carefully observe children's activity performance, judge children's development and mathematical cognitive level, adjust strategies in time, and give children more appropriate and personalized guidance.

In necklace-stringing activities, children in small classes especially want to be accompanied by several teachers. First, because the development level of children in the early stage of small classes is popular, the concept of "class" has not yet been formed, and I don't know how to classify them. Teachers need to provide concrete objects as classification marks and give hints to children to help them gradually establish and establish the consciousness of "holding the same characteristics" and then form a preliminary "class consciousness" Secondly, because of the teacher's company, children in small classes will play for a long time, and they are willing to show their necklaces to the teacher and experience the happiness of success and sharing. Third, children in small classes have a strong interest in necklaces, but their purpose and planning are not strong. They are often only satisfied with beading, and occasionally choose wooden beads of a certain color or shape according to their own preferences, but they may change and change at any time in the process.

Mathematics is everywhere in life, so the purpose of mathematics area is generally to understand mathematics knowledge from the initial perception to the final real life. Form the integrity, sequence, hierarchy, uniqueness and integrity of mathematics education content. Pay attention to the all-round development of children's knowledge, skills and emotions, and at the same time grasp the principles of goal, playfulness, interest, operability, integrity, difference and interaction, so as to make the math corner activities in small classes really flexible.
