新人教版小学数学二年级下册《1000以内数的认识》说课稿（The new version of the second grade primary school mathematics teaching book 1000 less than the number of known releases） 1000 less than the number of understanding releases Tags:. A textbook, said: 1000 less than the number of understanding this is the first section of PEP primary school mathematics fourth volume fifth units of understanding million less than the number of this unit. This part of the content in the entire digital learning system plays an important role, and the extension of it is 100 less than the number of knowledge, is the basis of understanding within a few million or even larger numbers, and this knowledge is widely used in daily life. Three examples, arrangement of teaching material of three hours to reach a target of 1000 less than the number of understanding. The design of 1 cases is mainly through the students practical understanding of counting, counting unit thousand, which perceived greater numbers, counting units found between every two adjacent relations are in decimal. 2 cases of teaching is to enable students to read and write 1000 within a few, and can say each number. 3 is 1000 less than the number of size. Then practice fifteen. I will be teaching content of the first period for 1 cases, 2 cases, 1000 less than the number of learning to read and write the number and the number of components, know between two adjacent digit decimal relations, will be within a few thousands. For this part, mathematics curriculum standard is described: recognition and reading and writing within a few million, said the order and position number of objects or things with numbers; can name each digit, each digit recognition significance, combined with the reality of material experience of large numbers the significance, and can estimate. Based on the above analysis and the new curriculum requirements, determine the class to achieve the teaching objectives are as follows: Knowledge and skills objectives: 1, let the students e
