Whole numbers are no better than any others! Practice plotting values on the number line as a passionate activist rises up and demands equity for all numbers, including fractions and decimals. Number Rights addresses number and operations standards as well as the process standard, as established by the National Council of Teachers of Mathematics (NCTM). It supports students in: Comparing and ordering fractions, decimals, and percents efficiently and finding their approximate locations on a number line. Building new mathematical knowledge through problem solving. Solving problems that arise in mathematics and in other contexts.

QUESTION & ANSWER

DAMIEN posed a good question:
=====================================================================




A natural number (i.e. 1, 2, 3, 4, 5, 6, etc.) is called a prime number (or a prime) if it has exactly two positive factors, 1 and the number itself. Natural numbers that have more than two positive factors are called composite1 has only one positive factor i.e. no.1 only. Hence 1 is neither prime nor composite.



answer: therefore 1 is not a prime or composite number.

NUMBER SYSTEM AND CLASSIFICATION
=====================================================================

Below is a diagram that shows the classification of the number system (i.e. the different types of numbers in the mathematical world).


Your Task is (1) to define what the following types of numbers and (2) to give some examples.
Please cite the source. 
An example on Integer is done for you. Do (2) - (5)
Post your answers as comments as follows
Name (index no.)
answer

(1) Integers

(2) Whole Numbers

(3) Natural Numbers

(4) Rational Numbers

(5) Irrational Numbers

========================================================================
Example:

Mr Johari (008)
(1) Integer
An integer (pronounced IN-tuh-jer) is a whole number (not a fractional number) that can be positive, negative, or zero. Examples of integers are: -5, 1, 5, 8, 97, and 3,043. The set of integers, denoted Z, is formally defined as follows:   Z = {..., -3, -2, -1, 0, 1, 2, 3, ...}

Note for T1 W2

[Preparation] Term 1 Week 2

Dear S1-07

Please take note of the following, in preparation of the Maths lessons starting next week.


1. Diagnostic Test

You will be sitting for the diagnostic test for the subject on Thursday (12 Jan 2017)
The purpose of this test is to gauge your understanding of various mathematical concepts, for the teachers to pace the lessons.

What will be tested?
  • What you already know
  • What you would be learning in this academic year
Other important information
  • Duration: 50 minutes
  • Electronic calculator is allowed to evaluate explicit numerical expressions; however, clear and systematic working is expected as omission of essential working will result in loss of marks
  • Answer all questions in INK.

2. Reading

To prepare your for next two weeks, you should start reading the following
  • Maths Textbook 1: Chapter 1 Primes, Highest Common Factor and Lowest Common Multiple
  • Maths Textbook 1: Chapter 3 Approximation and Estimation

Introduction to Mathematics

INTRODUCTION TO MATHEMATICS

LINK to Presentation
Enter as many words as possible that describes what you know about Mathematics since your first encounter with the subject.

Greetings and Ready for Learning!

Greetings and welcome to 2017, and new class :)

Before we meet at our first Maths lesson of the year, do take some time to do the following:

1. Accept the invite to the Maths blog with your sst email account.
  • You will be required to participate in activities delivered these platform.
  • Follow the blog so that you are informed of the posts put up
2. Go through various pages (in this blog), in particular - the "Habits of Mind" and "To do well".
  • These are useful because they are about inculcating good learning habits and self-discipline that are relevant in all contexts (not just Mathematics).

    What do you need to bring for your first Maths Lesson
    1. A4 Exercise Book - as your Maths Notebook - for all lessons
    2. A calculator
    3. Maths file (orange arch file): Write your name, register number, class at the spine
    Look out for more emails along the way... before we meet in Term 1 Week 2
