《用数对确定位置》是一个相对独立的单元,原来安排苏教版小学数学在第十册,去年教材改版之后安排在第九册的附录部分,现在最终被安排在第八册中。在此之前有很多老师上过这一内容,但是我也想尝试一下跳出原来的圈子上出自己的特色。因此在设计教案之前,我把这三本书放在一起进行反复地比较,同时仔细研读教参。 “The number of pairs to determine the location” is a relatively independent unit, the original arrangement of the Supian version of elementary mathematics in the tenth book last year, revised textbooks arranged in the ninth part of the appendix, and is now finally arranged in the eighth book. Before this many teachers had this content, but I also want to try to jump out of the original circle on their own characteristics. Therefore, before designing the lesson plans, I put these three books together for repeated comparisons while studying the teaching parameters carefully.
