This is the first-time students begin to peek into the world of fractions. We are not only looking to help students what the value of half of a number is, but also what does half of an object physically look like. There are a number of different ways to work on this concept with students. I find that helping find common ground between two extremes is good. I will show them a full container of a liquid and an empty container of the same liquid. I think ask them how I could have even amounts of the liquid in both containers. They quickly help us arrive at the concept of halves. These worksheets will help students become more comfortable with the concept of halves and how to identify it physically and in terms of math.

What is Half of Something?
The concept of halves is the first-time students will be c confronted with fractions. An important concept that we must know in mathematics and our everyday lives is possessing of halving a shape, object, or a quantity. Understanding this concept can ease out a lot of complicated problems in life. One of the best approaches I have found to explain this concept to youngsters is using the old phrase, “One for you, one for me!” You can display this by breaking 2 apart it 1s and follow that up with 4s, 6s, and 8s. In reality, we are actually taking it a step further than just expressing a fraction. We are working on how to divide something by 2s.
We run into the concept of half everyday on the devices that we use. You may be familiar with the battery symbol to the right. It is displaying that your device has half of its full battery power remaining.
What is Halving? Well, halving is the partitioning of a shape, object, or a quantity in two equal and identical parts. To half a geometrical shape, you just have to cut through the symmetrical axis (dead center). When you place the partitioned part on top of each other, they fit perfectly on top of each other. When it comes to halving numbers, you simply have to divide the quantity by 2. You are simply creating equal amounts for 2 people to share.
You multiply the quantity with the fraction 1/2 to half it. Consider the following example; Example: Jonny had 50 cents and he wants to divide it equally among his two sons equally. What is the share that each of his sons will receive? You multiply 50 cents with 1/2 and get the answer 25, this will be the share of each of John's son. The math on this pulls back to division 50 x 1/2 is the same as 50 ÷ 2. Like anything, the more practice you put into creating halves, the quicker and easier it will be for you.
