🦜🦚🦩The Intersection and Union of Sets🦜🦚🦩

 👦👧Welcome boys and girls to another Mathematics class. We will be learning about the intersection and union of sets.

What is the intersection of a set?👇

 

What is the union of a set?👇

Examples: 

Use the information below to find the intersection and union of the sets.

1a. A={ 2, 4, 6, 8, 10}                       B={ 1, 2, 3, 5, 6}

What is the intersection of sets A and B? 

        Ans= AB= {2, 3}

1b. Find the union of sets A and B.

       Ans= A U B= {1, 2,3, 4, 5, 6, 8, 10}

Use the information from the Venn Diagram to find the intersection and union of the set.

2a. What is the intersection of set P and Q?

        Ans= PQ= {12, 6, 18}

2b. Find the union of set P and Q.

         Ans= P U Q = {2, 3 4, 6, 8, 9, 10, 12, 14, 15, 16, 18}

👦👧Boys and girls watch the video clips to get additional information on intersection and union of a set.

It's now activities time boys and girls.👇👇

Task 1:

1a. Write the union and the intersection of set M and N.

                M= {3, 6, 9, 12, 15}           N= {2, 4, 6, 8, 10, 12}

2b. Use the information in the Venn Diagram to find the intersection and union of set of R and S.

Task 2:

1.     Use the information given below to create a Venn Diagram.

W= {the whole numbers from 0 to 4}     X= {the counting numbers from 1-5}  

 

 

                     WX={                       }               W U X={                                               }
