LESSON PLAN
School :
Subject : MATHEMATICS
Class/Semester : X / 2
Time allocation : 2 x 45 minutes
Standard Competence : 4. Using the logic of mathematics in solving problem associated with
compound statement and quantor statement
Basic Competence : 4.3 Formulate a statement equivalent to the compound statement or a
quantor statement is given
Indicator : 4.3.1. to prove equivalence two compound statement or quintifier statement
4.3.2. to investigate whether a compound statement is a tautology
4.3.3. to investigate whether a compound statement is a contradiction
4.3.4. to investigate whether a compound statement is not a tautology
I. Learning Goals
1. Students can prove equivalence two compound statement or quintifier statement
2. Students can investigate whether a compound statement is a tautology
3. Students can investigate whether a compound statement is a contradiction
4. Students can investigate whether a compound statement is not a tautology
II. Learning Material
Mathematics Logic
- Equivalence form between the two compound statements
- Tautology and Contradiction
III. Learning Methods
A. Learning Strategies : contextual teaching learning (CTL)
B. Method : expose, discuss
IV. Learning Activites Steps
Meeting 1
A. Pre- activitie
- The students are recall of the truth of compound statement
B. Core activities
- The student are guided to determine the truth value of some statements in the form of table
- The student are directed to find compound statement whose truth value equal
- One of students present the result of discuss, the other students observe
- The student are guided to make conclution about equvalence two compound statement or quantifier statement
- The student are given exercise
C. Post activities
- The student are given test
V. Reference
