🪂🏂🪂Infinite and Finite Sets🪂🏂🪂

 Welcome 👦👧boys and girls to Mathematics class. Today we will be going on an adventure where we will be exploring Infinite and Finite Sets.

What is a set?

A set is a collection of objects with common features.

What is an Infinite set?

An infinite set has unlimited or uncountable elements within a set.

Examples of an infinite sets

1.  A= {2, 4, 6, 8......} 

2.  B= {1, 2, 3,4.......}                    

The dots in the sets above indicates that the sets have no ending.

What is a finite set?

A finite set has limited and countable elements within a set.  

Examples of a finite sets

1. C= { cows, goats, sheep}

2. D= { apples, grapes, water melon} 

 👦👧Boys and girls watch the video clips for additional information on infinite and finite sets.

Now👦👧Boys and girls, we have learnt about infinite and finite sets. It's now activities time!!!

Task 1:

Search your home environment, write down all the possible objects and sort them into infinite and finite sets using the diagrams below. Infinite A and Finite B

Task 2: Write infinite or finite for each of the following sets.

1. set B {all the stars in the sky}________________ 

2. Set G {letters of the vowels} ________________ 

3. Set H { months of the year}________________

4. Set M { all the trees in the forest}_____________ 

5. Set K { all the students at Petersville Primary} _____________ 

6. Set R { the number of girls in grade 4} _______________ 

Task 3:

Match the terms to the correct definition.

Set                                     has unlimited members in a set.

finite                                 a collection of objects with common features.

infinite                                has countable members in a set.

curly bracket                       the number of elements in a set.

cardinality                            it's used to enclose the elements within a set.
