2. NUMBERS
Complex figures. A single digit can mean more than what
you think. I ask you two simple questions, ‘what is the
biggest number?’ and ‘what is the smallest number?’ The
number line goes on infinitely, so there is no biggest number
and no smallest number.In this book, you’ll learn some
interesting things about these scribbles...
Challenge: What is the biggest number
you know? Please answer this question.
3. THE USE OF MATH
Math is a very important life skill. You use math every day after
the age of 8; when you buy things, when you’re counting, when
you are measuring your weight, etc. Almost everything you do
has to do with numbers and math!
Challenge: When do you use math? Please
give five original answers.
4. OPERATIONS
The math term ‘operations’, doesn’t mean surgery. ‘Math
operations’ are the daily used math symbols, including: addition,
subtraction, multiplication and division! You would usually learn
addition first, then subtraction, multiplication and lastly division.
Operations are a key to math. The four operations are one of the
most important parts of math.
Challenge: What operation/s do
you know? Please explain how to
use that/those operation/s with
positive numbers.
5. PLACE VALUE CHARTS
With these charts you are separating numbers (page 1) into
categories. ‘Putting numbers into place value’ means organizing
digits into special categories. Categories such as: units, tens
hundreds, thousands, ten thousands,etc. Since the number line
goes on infinitely, the place value chart goes on infinitely too.
An example: 987,654= 9 hundred
thousands, 8 ten thousands, 7
thousands, 6 hundreds, 5 tens and 4
units.
6. EXPANDED FORM
Expanded form is also putting numbers into categories. When you
put a number into expanded form, you are turning the number
into place value, but with numbers. You add addition signs in
between the numbers, to show that a certain number plus
another/other number/s create a certain number.
An example: 123= 100+20+3 or 123,456=
100000+20000+3000+400+50+6
7. POSITIVES
‘Positive numbers’ are numbers above zero. This group of
numbers are most commonly used. As I said on page 1, numbers
go on infinitely. Positive numbers are the opposite of negative
numbers (page 8). Sweet and simple.
Challenge: Positive numbers are
the most commonly used set of
numbers, so what do you think is
the least used set of numbers and
why?
8. NEGATIVES
As I said on page 1, numbers go on infinitely. Challenge:
The new question is: Is there anything below Is -100
zero and if yes, what is it? The answer, of course more or
is yes. Those special numbers are called less than -1?
‘negatives’. Negatives always have a ‘-’ sign in
front of them. The trick is that negatives are the
opposite of positives (page 7). The biggest
negative integer is -1. Zero is the middle of all
numbers.
9. NUMBER LINES
Number lines are exactly what they sound of. Number.
Lines. Lines with numbers on it. These number lines are
great for addition and subtraction. Especially operations for
negative numbers on page 8.
