Interactive math game on adding fractions, 3rd to 7th grade math
This is an interactive math game on adding fractions for kids in 3rd, 4th, 5th, 6th and 7th grades. This takes the form of a multiple choice questions quiz online which kids can use to check their skills on fraction. This is also a drag and drop activity for children at different levels. To the right are the problems and to the left the answers. simply solve the problem and then drag and drop the correct answer that corresponds. At the end of each game, children will get their scores displayed. This is a flexible way to self-evaluate yourself.
When we add fractions, we are finding the total value of two or more parts. In order to add fractions, the denominators (the bottom numbers) of the fractions must be the same. If the denominators are not the same, we must find a common denominator before we can add the fractions.
One way to add fractions is by using a method called “vertical addition.” In this method, we write the fractions one above the other, with the numerators (the top numbers) lined up, and the denominators lined up below them. We then add the numerators together, and keep the denominator the same.
For example, let’s say we want to add the fractions 1/4 and 1/4. We write them vertically, with the numerators lined up and the denominators lined up below:
1/4
+1/4
-----
Now we add the numerators, which in this case are both 1. We get:
1/4
+1/4
-----
2/4
We now have the sum of the two fractions which is 2/4. We can simplify this by dividing the numerator and denominator by a common factor of 2, to get the simplified fraction 1/2. So the sum of 1/4 and 1/4 is 1/2.
This method of adding fractions can be used for adding more than two fractions, just keep adding the numerators and keep the denominator same.
1/4
+1/4
+1/4
-----
3/4
As we can see that when we added 1/4 + 1/4 + 1/4 we get 3/4.
It’s also very important to note that the fractions need to be written with the same denominator, and that denominator will be the least common multiple(LCM) of all the fractions, For example:
2/3
+3/5
-----
The LCM for the above fractions is 15. So the fractions will be written as:
10/15
+9/15
-----
19/15
Adding fractions can be a bit tricky at first, but with practice and understanding, it becomes easy and fun. It’s also important to understand when to simplify the fraction like we did in 2/4 to 1/2.
When adding or subtracting fractions, it’s important to remember to find a common denominator first, if the denominators are not the same. And always simplify the fraction if possible.
In addition to vertical addition, there are other ways to add fractions, such as finding a common denominator and then adding or subtracting the numerators, or by using a method called “cross-multiplication.” But vertical addition is a useful and straightforward method that students can use to add fractions.
