⌛️📱⏳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 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.
