Key Concepts & Vocabulary
TermDefinitionExample
Standard FormThe most common way we write numbers using digits (0-9).The standard form of 'four' is 4.
Fractional RepresentationExpressing a whole number as a fraction, often showing equivalent forms.The number 2 can be represented as 2/1, 4/2, or 6/3.
Decimal RepresentationExpressing a whole number as a decimal, often including trailing zeros to emphasize precision.The number 3 can be represented as 3.0 or 3.00.
Number LineA visual diagram where numbers are placed in order along a straight line, showing their relative positions.Marking the point '5' on a line with increments for 1, 2, 3, 4, 5.
Coordinate PairAn ordered pair of numbers (x, y) used to locate a specific point on a coordinate plane.The point (2, 3) represents 2 units right and 3 unit...

Core Formulas
Whole Number to Fraction Conversion
Any whole number $N$ can be expressed as a fraction by placing it over 1: $N = \frac{N}{1}$. It can also be expressed as equivalent fractions by multiplying both the numerator and denominator by the same non-zero number: $N = \frac{N \times a}{1 \times a}$.
This rule helps convert whole numbers into fractions and find equivalent fractional forms, which is useful for operations involving fractions.
Whole Number to Decimal Conversion
Any whole number $N$ can be expressed as a decimal by adding a decimal point and one or more zeros: $N = N.0 = N.00 = N.000...$
This rule allows us to represent whole numbers using decimal notation, which is important for understanding place value and performing decimal operations.
