good afternoon everyone i'm maika milikeran from bachelor in elementary education now i'm presenting my demo teaching in math five okay let's start good afternoon children i can hear you again good afternoon children okay how are you today children i'm so happy that you're all good now people we're going to start our lesson let's pray first okay okay christine can you read our prayer please bow your head and fill the presence of the lord the name of the father the son the holy spirit amen [Music] dear heavenly father thank you for giving us healthy body and sound mind we thank you for another opportunity to learn bless us with wisdom to understand our lessons and the join to learn with our classmates bless also our teachers as they impart to us the value of learning keep us safe in your love and kindness this we ask in the mighty and sweet name of our lord and savior jesus christ amen okay thank you so much thank you for that now i will check the attendance okay well checking that and dance can you please pick up all the paper under your chair and can you fix the chair please and sit down properly okay very good class no one is absent today now we can start our class okay last before we're going to start to our lesson proper i prepare a simple activity i will ask you a question okay try to look around at your surroundings what do you see or what do you observe different figures and shape good job you see different figures and shape all around isn't it wonderful class yes i'm happy that you appreciate all of that now let's start our activity okay i will give the instruction can you look around in your room or surroundings and observe what object has three or more sides i will give you two minutes okay two minutes and then tell to the class what object you see or you can show it later okay let's start who wants to recite first yes christine what object do you see yes good job a book what is the shape of the book it's a square and how about the sides how many sides you can count okay two three four good job it has four sides who wants to recite next yes paola what object do you observe yes picture frame how about what is the shape of the picture frame it's a rectangle then how many sides first one we also have four sides now all the things that you guys can see was made from different figures shapes in all forms and sizes now do you have any idea class what is our topic for today polygon spa very good it's about polygons but we will be focusing in properties of polygon that is a regular polygon and that regular polygon now let's start to know what is a polygon can you read it class the definition of a polygon good job now i will discuss what is a polygon a polygon came from the greek word polygon poly means many and gone means angles now i will give an example here for you to understand it well okay line segment if we will combine the four line segment we can produce a polygon now let's check where's the angles of this polygon let's count okay the sides is one two three four then how about the vertex the vertex is here the color blue in the side one two three and four then the angles let's count the angles okay here one two three and four good job class and i'll give the name according to the numbers of size and angles they have we have here different kind of polygons okay class we have here equilateral triangle came from the word try means three it has three sides and three angles second is the quadrilateral triangle came from the word quad it means four it has four sides and four angles next is the pentagon penta means five it has five sides and five angles next one is the hexagon hexa means six it has six sides and six angles the next one is the heptagon hepta means seven it has seven sides and seven angles and the next one is octagon octa means eight it has eight sides and eight angles and the nonagon nona means nine and it has nine sides and nine angles and the last one is the decagon they come instead it has 10 sides and 10 angles now class do you understand what is a polygon is good job now let's proceed to the properties of polygon that is the regular polygon and the irregular polygon now let's start to the regular polygon here's the definition can you read it class okay i will give an example of the regular polygons it said that the regular polygon it has all sides are equal length and all eternal angles are equal here here's the example class what is the what is the polygon here in the slide good job it is a pentagon now let's count how many sides pentagon have okay one two three 4 now its pentagon is equal to all of the sides and angles yes good job then now i will give another example here what follow gun is this good job it's an octagon and how many side octagon have yes good job it has eight sides and eight angles so it means octagon is a regular polygon good job now let's proceed to the irregular polygon irregular polygon is an equal size it means it it is the opposite of the regular polygon i will give an example okay class here's the example let's count the sides okay one two three four five it has also five sides but the measure of each side has equal yes correct it's not equal because look at the picture it also called a pentagon but it is not an equal side so it means it is a irregular polygon okay class i'm happy because you understand our lesson okay i prepared here another example okay class the different polygons with measurement okay you observe what can you say about the side of the polygon here in the set a good job it's all the same sides and measurement and how about the in the set b yes it's not equal because there's a four centimeter and two centimeter and all the sides of the set b is equal no it's not correct and how about in the set a yes equal because they are all two centimeter correct the polygon in the set a has all equal sides and all equal measurement and that is a regular polygon and the set b is not equal the measurement is not equal there's a poor centimeter and two centimeter signs so it is called irregular polygons now class do you understand the irregular and regular polygons now okay let's have a short activity okay can you classify the following polygons as to regular or irregular polygons okay let's start in the first picture good job it's regular polygon because it has equal sides and angles how about the second picture good job it is a regular polygons because it is not equal how about the other picture good job it is regular polygons and that another picture good job it is irregular polygons and the last picture yes good job it is a regular polygon okay very good class now can i ask you what is a polygon very good and now what is a regular polygon very good all sides are equal and the angles can you give an example of a regular polygon if you really understand good job how about what is a regular polygon very good can you give an example of a regular polygon very good class now you understand all of our lessons because you understand and identify what is the difference of the regular and irregular polygons now let's proceed to your final activity look at the different pictures of the polygons now put it in the right place put it in the regular polygons column or the column b in the irregular polygons okay class you can start answering and later on we will see your answer okay let's check your answer later i'll give you five minutes to answer okay okay let's start to check your answer what is the answer in number one it is regular or irregular yes good job it is regular then what is the number two yes good job it's also a regular polygons because it has an equal sides how about number three good job it is a irregular polygons because it has an equal sides how about the number four good job it's also irregular polygons and the last one number five yes it is regular polygons great job class because you understand our topic for today that is a polygon and regular and irregular polygons now let's go on to your assignment ok you will draw different kind of polygons five regular and five regular now you can be creative you can use different kind of materials if you want okay class have a good day and again i'm teacher micah thank you for listening and participating to our lesson you
