TOPICS:SETS SUB TOPICS: UNDERSTAND THE CONCEPT OF SET LEARNING OUTCOME LEARNING OUTCOME: Represent sets by using Venn diagrams STLA: 1. Ask the student to draw any geometrical shape 2. Introducing the geometrical diagram 3. Represent the set using the Venn diagram 4. List all the elements in the set based on the Venn diagram 5. Give hand out for the exercises

CLOSED GEOMETRIC DIAGRAM

VENN DIAGRAM  Draw the Venn diagram representing each set below: S = { Even numbers less than 10 } Answer: S = { 2,4,6,8} S

EXERCISE 1 Draw the Venn diagram representing each set below: 1. G = { multiples of 4 from 8 to 24} 2. Q = { -1, -1/2, 0, ½, 1 } 3. N = { States in Malaysia starting with the letter P } 4. R = { a, e, o, i, u }

VENN DIAGRAM List the elements in the set below: List the elements in the set below: LION CAT GOAT DOG BEAR M Answer: M = { Lion, Cat, Dog, Goat, Bear}

EXERCISE 2 List the elements in the sets below: PHYSICS CHEMISTRY BIOLOGY T D

Topic : Sets Learning outcomes : List the elements and state the number of elements of a set STLA : Discuss the list of elements and the number of the elements of a set.

SET OF ANIMALS

A = { 2,6,4,8, } The number of elements in set A = 5 EXAMPLE 1

B = { 7,2,5,3 } 1243 The number of elements in set B = 4 EXAMPLE 2

C = { The Factors of 24} C = { The number of elements in set C = 8 EXAMPLE 3 1 1,2,4,3,8,6,12,24 }

D ={x : 10 < x < 30} The number of elements in set D = 21 EXAMPLE 4 D = {10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20,21, 22, 23, 24, 25, 26, 27, 28,29,30}

The number of elements in set A is denoted by n(A) The number of elements in set B is denoted by n(B) The number of elements in set C is denoted by n(C) The number of elements in set D is denoted by n(D)

A = { 2,6,4,8, } The number of elements in set A = 5 n( A) = 5 EXAMPLE 1

B = { 7,2,5,3 } 1243 The number of elements in set B = 4 n( B) = 4 EXAMPLE 2

C = { The Factors of 24} C = { The number of elements in set C = 8 1 1,2,4,3,8,6,12,24 } n (C ) = 8 EXAMPLE 3

D ={x : 10 < x < 30} D = {10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20,21, 22, 23, 24, 25, 26, 27, 28,29,30} The number of elements in set D = 21 EXAMPLE 4 n ( D) = 21

State the number of elements in each set below a)A = { Melaka, Johor, Perlis} b)B = { 10, 11, 12, ……….20} c)C = { Integers between -3 and 6} EXERCISES
