Hi

I have reviewed the assessment given in week2/3 and have found the following:

- It was generally well done and I am particularly impressed by the mathematical presentation from some of you.
- There is a need to relook at the way some of the mathematical symbols were used in your working especially with the use of --->
- While some students are familiar with algebra, I noticed some students are not comfortable to use algebra in problem solving

Please keep up the great work.

Mr Jo

Dear wonderful 109ians,

*Thank you for your comments on the Locker question. It is certainly an introductory lesson on our first chapter on ***HCF and LCM**.*It is important that*

Your follow up task is to find as much information on the subtopic below:

- Composite Numbers
- Prime factorisation
- Index Form

Please give your findings using any of the following platforms:

- simple comments (to this blog entry)
- use reference from your Maths e-textbook or any other reliable Maths books
- include reliable you-tube on this topics (pls quote source)
- maths dictionary
- sample examples from reliable resources to illustrate your understanding of subtopics

you collaborate as a class to reinforce or correct one another

support your friends with examples etc.

deadline: week 4

Hi**Quiz time: **

I have attached a mathematical dictionary for your use and reference.

Find the definitions of the following terms with examples (first one to post and got them correct stand to win a mathematical prize)

- Prime number
- Natural number
- Rational Number
- Vulgar Fraction
- Indices

An impending headache to the administrator in planning the locker operation in SST. He seeks your advise on how to resolve this issue:

*Here is the problem*:

Task: In aSST, there is a row of 100 closed lockers numbered 1 to 100. A student goes through the row and opens every locker. A second student goes through the row and for every second locker if it is closed, she opens it and if it is opened, she closes it. A third student does the same thing for every third, a fourth for every fourth locker and so on, all the way to the 100th locker. **The goal of the problem is to determine which lockers will be open at the end of the process.**

**Sample Questions:**

In words, explain your thinking to the following problems clearly. Be sure to use appropriate mathematical language and methods:

• Which lockers remain open after the 100th student has passed?

• If there were 500 students and lockers, which lockers remain opened after the 500th student has passed?

**Further Activity:**

Identify another problem that uses the same method or technique to solve and post it to this blog

'A **number** is a mathematical object used in counting and measuring. A notational symbol which represents a number is called a numeral, but in common usage the word number is used for both the abstract object and the symbol, as well as for the word for the number. In addition to their use in counting and measuring, numerals are often used for labels (telephone numbers), for ordering (serial numbers), and for codes (ISBNs). In mathematics, the definition of number has been extended over the years to include such numbers as 0, negative numbers, rational numbers, irrational numbers, and complex numbers.' wikipedia**Task 1:** **View the following video to have a better perspective of maths**

**Task 2: Number System through the years**

Another interesting factor to note is that numbers is a form of a universal language and appears in every civilization.

history of Maths

Identify 3 points that you have discovered from the video.

Identify 3 points that you have discovered from the video.

Identify a civilization and do a brief presentation of not more than 1 minute on the number system of the chosen civilization. You may identify, if any, a key pattern of the number system of that civilization with our present number system. You may choose any more of on-line presentation and upload to this site.

1-09 Maths Class Learning Policy from the following perspectives:

**Learner:**

**Educator:**

**Environment:**

**All rules must be adhered to at all times (during class)****_____________________________________**

- We respect the teacher by not using vulgarities/bad words.
- We ought to close our macbooks on when teacher is talking.
- We must keep quiet when the teacher is teaching
- Hand in homework on time

- Must make the lesson interesting
- Respect the students
- Must not be Biased
- Makes lessons interesting
- Give time for students to prepare for lessons
- No excessive homework
