How do Division and Sharing Relate? When understanding the division operation, a lot of students face difficulty. It is not a simple operation like addition and subtraction. A teacher uses the concept of sharing when helping the students grasp the concept of division. The reason behind it is that division and sharing are related. Whenever we talk about sharing, we instantly know that we have to apply the division operation. Sharing is a keyword in a word problem that indicates that it is a division word problem. There are two types of sharing, equal sharing and unequal sharing. When we talk about unequal sharing, we might have to use the concept of ratios, which is also an application of division operation. Equal sharing requires simple division. Example: Tony has five sons. He gave $100 to his eldest son and asked him to equally share it with his other four brother. How much money will each of Tony's son receive? Solution: When you read the problem, you know that it talks about sharing which requires you to apply the division operation. You know the total amount that needs to be shared which is $100 and you know the number of shares that the amount must be divided in, which is five. You simply divide $100 by 5 and you get $20. Each son's share will be $20. These worksheets and lessons show students can be related to sharing items between differing numbers of people. This is a great way to introduce the topic to students.
