This document discusses concepts related to whole numbers in mathematics. It explains the meaning of cardinal and ordinal numbers. Cardinal numbers are used to count quantities, while ordinal numbers indicate position in a list. The document differentiates between types of numbers like integers, fractions, and real numbers. Students participate in activities to practice using cardinal and ordinal numbers to describe months, dates, and rankings. They also use one-to-one matching to compare sets and identify relationships between quantities.
