Identify the cardinal number for a set
what is cardinal number or cardinality?
The numbers of elements in the set"
What are equivalent sets?
If two sets have the same number of elements
When are sets equal?
Sets are equal if they contain the exact same elements and the same number of elements, regardless of their order.
The students in your class are a subset of all the students in your school?
What is TRUE?
I am placed where two sets overlap, where am I?
Cardinal number of the set {5,10,15,20,25,30}

Are the following 2 sets equivalent? Why or why not?
M= {26, 65, 98, 125, 654}
C= {90, 53, 76, 13, 890}
Yes, they are equivalent because both sets have the same number of elements.
Are the sets equal? Why or why not?
Set A = {6, 2, 9, 11, 3}
Set C = {6, 9, 2, 3, 14}
No they aren't because they do not have the same exact elements.
What is FALSE?
I am a symbol in a set, what am I?
The cardinality of the set of parishes in the county of Cornwall.
5
Are the following 2 sets equivalent? Why or why not?
P= {l, m, n, o, p, q}
W= {p, l, n, o, m}
No, they are not equivalent.
Set P cardinality= 6
Set W cardinality= 5
Set 1= {a, b, c, d, e, f, g}
Set 2= {c, e, a, b, f, g, d}
Yes they are equal
If A = {x, y, z}, B = {s, t, u} then A n B is { }.
What is true?
You joined all the members in two sets to make one. What have you formed?
What is a union?
The cardinal number of the set of prime numbers less than 20
8
Determine if the set of number of letters in EDUCATION and the set B= {q, w, e, r, t, y, u, i, o} are equivalent.
Yes, they are equivalent.
Create 2 sets that are equal (write on your whiteboard)
*teacher will check*
All equivalent sets are equal sets.
What is FALSE?
I am a symbol used to show the set of?
What are curly brackets ({ })?
Set A= {Sharon, Pam, Keisha, Marsha, Anita }
The cardinal number:
6
Determine if Set B = {1, 4, 9, 16, 25} and D = {2, 3, 5, 7} are equivalent.
No, they are not equivalent.
Set B has 5 elements
Set D has 4 elements
Are these sets equal? Why or why not?
Set 1= the number of whole numbers greater than 0 but less than 10
Set 2= the number of natural numbers less than 10
Yes, they are equal. They have the exact same elements.
If X = {a, b, c} and Y = {c, d, e} then X U Y = {a, b, c, d, e}
What is TRUE?
I am part of a large set, so I am a _____ of that set.
What is a subset?
