"Chickens and rabbits in the same cage" is a popular interesting topic in mathematics in China. For some smart and studious children, this topic is full of interest. The more you do, the more you love to do, and the more you chew, the more you work hard. For children with poor acceptance, it is like chewing wax, tasteless and difficult to swallow. Teaching methods from intuitive drawing, to list, and finally to abstract assumptions, from simple to complex step by step, linking with real life, giving inferences, but some children still don't understand. Years of teaching experience show that some children can learn this knowledge without a teacher in primary school, which can be described as self-taught; Some children can only learn by teachers, while others can't, and teachers often make the greatest contribution to these children. This is the so-called students with learning difficulties, euphemistically called "intelligence doesn't sneak in", but I just won't! There are two questions in today's quiz, both of which are done in the textbook and explained one by one. There are still six children who are wrong. Helpless, find another way, so that students can't be small teachers, and it may be better to pair up one by one! I hope I can pass the unit exam smoothly next Monday, and the results won't surprise me.
