I taught the mathematics and science as a subject.
My strategy is to first explain the concept then practice and practice the number of questions.
Algebra
Geometry
Number system
Ratio and proportion
Percentage and etc

I explain through the example so that student can understand in a easy way then I give a chance to student for solving the question at least try.

Science:
concept of topics from basic to perticular subject through day to day example.
I explain through the power point and pictographs representations so that image can be read easily and visual representation will remain in mind forever.

Test:
After a perticular time , I take the test also so that student can know about the how much student know about the topic,
Test is important to know about the level of strength at topic.
It provides the confidence to the student also.
Feedback:
I give the feedback to student so that student can know where they can improve for future.
I do the excercise of perticular topic, these excercise help to student for doing the practice.

Sometimes some student do not understand the topic or they take more time to understand.
For these students, I give my personal time to these students after the class so that I can cover up the topic and stay with all the class.
Student are the future of our society so that I know they are the pillars of our society, there teaching and learning should be good so that foundation will stay like a rock.
