This document discusses key concepts in whole numbers including definitions, even and odd numbers, place value, and operations. It also examines common student misconceptions and challenges with whole numbers. Effective teaching of whole numbers requires strong pedagogical content knowledge (PCK) and the use of teaching aids such as concrete materials, print and non-print media, and technology.

KonsepNomborBulatDefinisinomborbulat (whole number)Nombor yang terdiridaripada 0,1,2,3,4,5,6,7,8,9…. some people say that whole numbers can also be negative, so that would make them exactly the same as integers. And sometimes people say that zero is NOT a whole number. So there you go, not everyone agrees on a simple thing!

6. Sample questionWhat is the place value of the figure 8? The figure 8 has a value of eight tens, or 80.6

7. Writing and describing whole numbers When describing whole numbers, we must remember the place values of the original digits. However, some digits are 'joined' in their description. For example - when describing the number 35, we do not say 'three tens and five units', but instead describe it by the more common name of 'thirty five'. 7
