Objectives:

* Show multiplication of whole numbers as repeated addition using the number line or array, etc.

* Transform an addition sentence into a multiplication sentence

Multiplication can be expressed as repeated addition, where each addend is the repeated number of objects, and the number of times it will be added is the number of groups.

A multiplication sentence is a short way of expressing the addition of the same number.

Number of objects in each group x number of groups = total number of objects

This module discusses multiplication of whole numbers. It emphasizes that multiplication sentence is the short way of adding the same numbers, and that it is basically expressed as repeated addition.

Good explanation about rational numbers and I want to share something about rational numbers,Rational numbers can be whole numbers, fractions, and decimals. They can be written as a ratio of two integers in the form a/b where a and b are integers and b nonzero.
