• Review of representation of natural numbers

  • Integers

  • Rational numbers on the number line

  • Representation of terminating / non-terminating recurring decimals, on the number line through successive magnification

  • Rational numbers as recurring/terminating decimals

  • Examples of non-recurring / non-terminating decimals

  • Existence of non-rational numbers (irrational numbers) such as √2, √3 and their representation on the number line

  • Explaining that every real number is represented by a unique point on the number line and conversely, every point on the number line represents a unique real number

  • Existence of √x for a given positive real number x (visual proof to be emphasized)

  • Definition of nth root of a real number

  • Recall of laws of exponents with integral powers

  • Rational exponents with positive real bases (to be done by particular cases, allowing learner to arrive at the general laws)

  • Rationalization (with precise meaning) of real numbers of the type 1/(a+b√x) and 1/(√x+√y) (and their combinations) where x and y are natural number and a and b are integers
