Division and Divisibility
About the Division and Divisibility Lesson
This lesson introduces students to rules for divisibility.
• To be able to recognize the three ways of writing division problems.
• To be able to explain what divisibility means.
• To be able to use the rules for divisibility to determine if numbers are divisible by certain other numbers.
When we say that a number is divisible by another number, we mean that the number can be divided by another number without leaving a remainder. For example, 12 is divisible by 4 because 12 ? 4 = 3. 12 is not divisible by 5 because 12 ? 5 equals 2 with a remainder of 2.
