Adding Fractions with Like Denominators Worksheets
When it comes to any operation when working with fractions, the first thing you need to diagnose is the denominators (bottom of the fractions). Are they the same or different? If there has been a shift between them, you will need to recalculate your strategy towards approaching them. If they are the same, it is time to just focus on the numerators (top numbers). Just find the sum between them and leave the denominators as is. These worksheets and lessons show students how to add fractions that have like denominators. If the lesson does not solve it all for your students, move on to the practice sheet and see how they do there. If they are still struggling, have them slowly work through the guided lesson and the explanation for it. We have not come across many students that this skill does not stick with, after completing that progression.

- Creating Improper Fractions Step-by-Step Lesson- This is very basic. We do not ask them to create mixed numbers, just top-heavy fractions.
- Guided Lesson - We go both vertical and horizontal with these.
- Guided Lesson Explanation - I show you a nice way to set up these types of problems. It makes them very easy to solve.
- Horizontal Worksheet 5-Pack -All the problems are set up in a horizontal orientation. You will see this often on Regional exams.
- Practice Worksheet -I provided a line below each problem for students to write their final answers.
- Matching Worksheet - Match the fraction operations and their sum.
- Adding Unlike Fractions Lesson and Practice - This is a set right into the next skill set that you see at 5th grade. This is for advanced students.
- Add and Reduce Unlike Fractions Practice - Again, I want to stress that this is for advanced students and is above this standard.
- Answer Keys - These are for all the unlocked materials above.
I went through the reduced fractions in here. I added all the steps, so if you are not to reduction yet, the answer is there for you, too.
- Homework 1 - Add the fractions and simplify to the lowest terms.
- Homework 2 - In this fraction, the denominators (bottom numbers) are same.
- Homework 3 - So add the numerators (top numbers).
Lots of white space in here and some top-heavy and real small (big denominators) are mixed in there, too.
- Practice 1 - Make sure to write the addition value with the denominator which was same.
- Practice 2 - Just add across the top and you are good to go.
- Practice 3 - Yeah, some of these are crazy top heavy.
Math Skill Quizzes
I angled the fractions to the top of the box to allow for more work room for students.
- Quiz 1 - Grab up the tops and you are good.
- Quiz 2 - These are a bit more round for you to work with.
- Quiz 3 - These can make the difference.
How to Add Fractions with Like Denominators
Adding fractions with the same denominators is a very straightforward process given if the rules are followed the right way. This lesson will be addressing the fractions that have the same denominators. We will be including all the necessary information you will need to work with common denominators.
The equation shows the rule of addition applied. For instance, if you are dealing with same denominators, the answer to the sum of the numerator (a and c) over the common denominator. Remember that a fraction usually refers to the number of parts in the whole. The WHOLE here refers to the number that lies in the denominator. So, all you need to do is add everything and keep everything on the same point of reference.
Here are some of the instructions.
For add fractions, denominators need to be equal and complete the steps to add the two fractions.
1. Build every fraction so that the two denominators become equal.
2. Add the numerators of the fraction.
3. The new denominator will be denominator of the build-up fractions.
4. Reducing or simplifying the answer, if needed.
a. Factor numerator.
b. Factor denominator.
c. Cancel-out fraction mixes that have value of 1.
d. Re-writing the answer as reduced or a simplified fraction.
e. Remember, DON'T ADD THE DENOMINATOR, they stay as is because they are the same.
