Lesson one 1) Counting numbers : Fifth Primary The Numbers Any numbers you can use for counting things: 1, 2, 3, 4, 5, ……………….. It is usually represented by letter C Notes : Does not include zero or negative numbers or fractions or decimals. Book P. 2 &P. 3

2) Natural numbers : The counting numbers + zero. It is usually represented by letter N Notes : Does not include negative numbers or fractions or decimals. Remarks:  N = the set of counting numbers  { 0 }.  N – {0}= the set of counting numbers.  The set of counting numbers is  the set of natural numbers.

Remember The set of counting numbers = { 1, 2, 3, 4, ……..} or C = { 1, 2, 3, 4, ……..} It is an infinite set The set of Natural numbers = { 0, 1, 2, 3, ……..} or N= { 0, 1, 2, 3, ……..} It is an infinite set  The smallest natural number is zero.  The smallest counting number is one  C  N  N – {0}= C  N ∩ C = C
