The book teaching material analysis:

(a), the content and writing characteristics of this textbook.

Volume 12 of the six-year revised textbook includes the following contents: proportion, cylinder, cone and sphere, simple statistics (II), arrangement and review. Compared with the original nine-year compulsory education textbook, the following adjustments have been made.

1. Move "percentage (2)" to the volume 1 1.

In the original nine-year compulsory education textbook, due to the limitation of class hours, the content of "percentage" is divided into two parts, which are arranged in the eleventh and twelfth volumes respectively. After this revision, due to the adjustment of the content, the class hours have changed accordingly, so it is very appropriate to move the "Percentage (2)" in this volume to the eleventh volume from the point of view of class hours and content cohesion.

2. Adjust the "Classification and Review" section.

The main change of this unit is to adjust the contents of the previous textbooks and make corresponding changes to related exercises, such as deleting the related contents and exercises of "number and folding" and adapting the related exercises of fractional addition and subtraction, fractional and decimal mixed operation and so on.
