GDZ control and measuring materials (KIM) in chemistry, grade 9 Strelnikova Vako

At the end of 9th grade, students will face their first serious test - the exam. They will be given assignments in the GIA format, and in another two years – testing according to the Unified State Examination standard. Will help you achieve successful results GDZ in chemistry!
KIMs in chemistry are a collection of questions and tasks that allow you to implement various forms of control:
- current;
- thematic;
- final.
The manual prepared by E.N. Strelnikov, became an integral part didactic complexes teachers working according to the textbook O.S. Gabrielyan. In 9th grade, chemistry lessons examine the characteristics and properties of elements, the features of their interaction, the nature of the formation of compounds, etc. The course covers topics that are difficult to understand and requires total immersion into the subject.
KIMs in chemistry - to knowledge in a straight line!
Gradually going through questions and assignments of all levels of difficulty for each section of the textbook, the student will repeat the lesson material, learn to apply knowledge in practice, and receive basic training for exams. Using the workbook, students and their parents will have the opportunity to independently work through each topic and compare their achievements with the standard.
If the result is disastrous, additions to the tests will help. With them, the correctness of drawing up reaction equations and the progress of solving problems will no longer raise doubts. GDZ online is a storehouse of knowledge! Discover this handy tool, and chemistry will turn from a difficult and mystical science into an adored subject and an accessible hobby!
