TYPES OF NUMBERS

Good morning everyone, welcome to the first lesson from Math Klass. Today, we will be looking at the types of numbers. There are different types of numbers with different names and I will be using plain language to explain the types.

WHOLE NUMBERS: These are numbers with no fraction (1/2) or decimal part (0.3). Examples are 0, 1, 2, 3, 4….

NATURAL NUMBERS: These are the whole number from 1 and up. These can also be called counting numbers.
Examples are 1, 2, 3, 4, 5….

INTEGERS: These are both negative and positive numbers.
Examples are …-3, -2, -1, 0, 1, 2, 3…

(I hope you are following the sequence)

RATIONAL NUMBERS: You can call these numbers fractions but in a simple term, when you can divide one integer by another integer. For example
1/2, -8 (means -8/1), 0.2 (means 2/10) and 1/3

IRRATIONAL NUMBERS: These are number that cannot be written as fractions because when you divide them, the decimal goes continuously without repeating. Here I will differentiate between rational and irrational number. Some teachers call these numbers Surd.
1/3 is a rational number and the decimal is 0.333333333….(continuous and repeated)
Ѵ2 (root 2) is an irrational number, it will give you 1.4142….(continuous without repeating)

Can you see the difference now? Try and give more examples of irrational numbers in your jotter. Have you done that? Let us proceed

The last type is the Real numbers.
REAL NUMBERS: All the types of numbers can be found in real numbers category.
Examples are 2, -1, ½, 3.142… and so on.

These are the types of numbers that we will come across in this class. I believe you have gained something from today’s topic; this is a preparatory lesson for those that will be joining me in the Google Classroom.

Assignment: 23/2/2019
Classify each number in as many categories as possible.
e.g 53 – natural number, whole number, an integer, rational and real number.
1. ¼
2. -5
3. 1
4. 0.2222…..
5 . -10/5
Please post your answer in the comment section. Don’t forget to practice on your own and feel to ask any question. See you next Saturday and have a blessed day.🖐🖐🖐

NUMBERS FOR KINDERGARTEN CLASS

(Mary’s mother was teaching her daughter how to write numbers)
Mummy Mary: Mary! Mary!! Can’t you write 2? Look at David; are you not in the same class? David can now write 1 -10.
The next thing you will hear is Abara/iko (spanking Mary). Why?

Mummy Mary, Daddy Isaiah, Uncle Robert, Brother Kola, Sis Debo come here o.🤨 Please in the name of God; stop smacking these children in the name of assisting them with Mathematics homework. It is not their fault. Have you ever asked David‘s mother what method she was using to teach David at home that helped him to get to that stage? Teachers alone cannot do it. Let us learn to assist them correctly. Without love, you cannot assist them with Math’s homework.
Kindergarten class is the most crucial and foundational stage of learning mathematics, it prepares the children ahead of the complex task and at this stage, most children learn how to count, recognize and develop a basic knowledge of how number works. It is too early for age 3 children to be writing 1-10, you can force them to write it but they will not understand the basic sense of how the number works. This is where the problem begins. Ask any class 3 child to recite multiplication table 1 -12. They will recite, write and even compose song with the tables but give them a word problem on multiplication table, 90% of them will not be able to solve it, teachers will teach them in the class by the time get home, they will not remember anything and the work will now become a burden to the parents, blaming teachers for everything.
It is neither the teacher’s fault nor the children. It is due to the poor foundation of those Mathematics concepts they had. It is not too late. Join us @ Math’s Klass on Facebook on Saturdays for Math lessons for kindergartens in order to assist your children at home. It’s going to be fun. Feel free to post your comment in the comment section. Till then, STOP CANING THEM.🙏🙏🙏🙏🙏🙏

THE WALL OF JERICHO CALLED MATHEMATICS PROBLEMS

MY BURDEN
I am Yemi Olajide, a professional Mathematics and Physics teacher from Nigeria. I left the shore of the country for further studies in the 21st Century in Leadership and Learning.
Everyday, I have my messenger and email inboxes full of messages from my students asking for assistance with their Mathematics assignments. Specifically today, I was down because it took me two hours to assist a J.S.S 3 student to complete a simple question from his Mathematics assignment that supposed to take only 15minutes. Please check this scenario out:
Find X, if 2/5 = X/6
The student solved the question correctly through cross multiplication method but his brother assisted him and he was afraid of the test coming up the following day because he did not understand the topic. Asked him reasons for using the cross multiplication method and he said: “my brother asked me to put a big cross in the middle”. I had to start all over again from the concepts division, multiplication, fractions and ratios.
From that scenario, I concluded that solving mathematics problems can be very challenging to many students because they do not understand the concepts of the topics taught in the classroom due to traditional methods of teaching mathematics thereby creating problems for parents, guardians at home. Research shows that 70% of the homework given is solved by the parents.

SOLUTION
Introduction of pragmatic approach alongside with traditional method of teaching that is student-centred will be the best gadget to stand against the wall called Mathematics problems that are creating fear in students and to reduce the burden of homework on parents and guardians.
A pragmatic approach can be defined as an approach relating subject concepts to the environment. There is no mathematics concept that you cannot relate to your environment. At a seminar (Skype Seminar) organized by a private school in Lagos, Nigeria. A teacher said that not all Mathematics concepts can be related to the environment especially the Inequality. That is incorrect. There are a lot of things happening in our environment that we can use to explain inequality; you just need to think out of the box to get what you need. For example, you can start the class by asking the students questions relating to Inequality.
Can 16 years old person vote in Nigeria, If No, why?
What is the voting age in Nigeria?
From the engagement with the students, they will tell you that it is either you are 18 or more than 18 years to vote in Nigeria. Explain the inequalities signs and ask the students to write their answers in mathematics form. With this approach, you have removed the abstractness of the topic and your students don’t need to memorize anything.
NEXT STEP
You will need your pen, exercise book (Jotter), WiFi (data) and follow, like, and share this page. Volunteers are needed to join the group. We will start from the scratch “What Is a Number’’, chat with me every Saturday on this page and together we can break the wall.
