Comparing the number of objects is a scientific activity in small classes last semester, which aims to let children master the "one-to-one correspondence" comparison method and compare the number of objects correctly. Fully prepared before the activity, there are not only various teaching AIDS, but also various operating materials for children to operate and master. First, the language description is incoherent. At the beginning of the activity, the story of the teacher fishing with a kitten aroused the children's interest. The first kitten caught two fish, and the second kitten caught three fish. Ask who catches more.
