Sec 2 Math 20/04/09

Date: 20/04/09

Day: Monday

Students present: Myint Myat, Ye Naing, Thin Nwe

Students absent: Nil

Teacher (main and assistants): Jasper

Subject: Math

Topic: Direct and Inverse Relationship


Teaching process

Concepts taught:
- Thinking process of attempting such questions.
- Linking the word relationship to two parties, linking the relationship between the two parties as the equation.
- Thought process imparted:
a. Locating the two parties involved in the question (alphabets, or things)
b. Finding out the relationship between the two (direct or inverse)
c. Creating an equation to link the 2

- Highlighted importance of stating that K is a constant.
- Fortified the knowledge and difference between constant and variable.
- Understanding that the constant (K) will never change in the same question
- Understanding basic graph theory (as X increase, Y increase)
- Learning to draw inverse and direct graphs
- Understanding the specialties in the various graphs (eg. straight line, pass through origin for direct graph, note the axes)

- Understanding how to prove that two variables are inverse, (vt = k, where k is a constant)
-

Example questions gone through: 2A Math Tutor Assessment Pg 44, 48, 51

Practice questions given: As above



Post-teaching

General comments of students:

- Ye Naing and Thin Nwe are able to attempt the questions at a smooth speed.

- Ye Naing and Myint Myat occasionally forget to include (where k is a constant)

- Myint Myat is still quite slow in attempting the questions

- All are able to grasp and concept and mechanism behind the topic better. Will avoid mistakes in drawing incorrect graphs (curves)

Improvement points of students:

- Myint Myat to practice more

- All to read the question more carefully and underline and annotate more often
