Adding Subtracting Fractions Unlike Denominators – In this lesson, students will learn to solve addition and subtraction problems with different denominators. Students will learn methods and strategies for solving these problems and practice solving them using the worksheets.
This lesson includes some modifications or additions that you can make if you wish, which can be found in the Lesson Options section of the Classroom Procedures page. All optional modifications for this lesson are specific to the activity. An optional addition to this lesson is for students to create their own war problems on index cards, creating different levels of difficulty.

Each lesson plan provides you with a classroom procedures page that lists a step-by-step guide to follow. You don’t have to follow the guide exactly. The guide helps you organize the lesson and details when distributing the worksheets. It also lists information in the blue box that you may find useful. You’ll find lesson objectives, state standards, and how many hours a lesson should last in this area. In addition, it describes the supplies you will need, as well as what to prepare in advance and how. The only supplies you will need for this lesson are scissors. To prepare in advance for this lesson, you can gather supplies and copy materials.
This lesson includes a Lesson Options section that lists a number of suggestions for activities that could be added to the lesson or alternatives to those already in the lesson. All optional modifications for this lesson are specific to the activity. You can have students create their own war problems on index cards, creating different levels of difficulty. Students can play in groups of three or four. If you have students who struggle, you can make sure they only use denominators less than 6. Finally, if you have students who need more of a challenge, you can use larger numbers or combine three numbers in the expression to make it more difficult.
The Teacher’s Notes page contains a paragraph with additional instructions and things to think about as you begin to plan your lesson. This page also contains lines that you can use to add your own notes as you prepare for this lesson.
Adding And Subtracting Fractions With Unlike Denominators — Process
Fractions: Addition and Subtraction Unlike denominators, the Lesson Plan covers three pages of content. The lesson begins by pointing out that you must have a common denominator (the same denominator) to add or subtract fractions. The lowest number in the fraction is called the denominator. In class, examples of what is common and what is different (different) are shown. To find the common denominator, you need to find the least common multiple.
For the example problem 2/3 + 1/9, we first need to find the least common multiple of 3 and 9. The multiples of 3 are 3, 6, 9, and the multiples of 9 start with 9. Therefore, the least common multiple is 9. Then you must multiply both the numerator and the denominator by 3 with the first fraction to make a common denominator, because 3 x 3 = 9 (the new denominator). The original fraction is 2/3, so the new fraction is 6/9 (2 x 3 = 6 and 3 x 3 = 9). Then you can easily add fractions. 6/9 + 1/9 = 7/9.
The next lesson shows another example of addition and subtraction using the same process. He then shows an example involving a mixed number. For mixed numbers, you must first change the mixed number to an improper fraction. Then you solve using the same method! Your final answer can be written as an improper fraction or you can convert it back to a mixed number.

Fractions: Addition and Subtraction Unlike denominators, the Lesson Plan includes three worksheets: an activity worksheet, a practice worksheet, and homework. You can refer to the guide on the Classroom Procedures page to determine when to distribute each worksheet.
For the activity worksheet, students will play a fun war game using the provided cards (which they will need to cut out from the worksheet). To play, each student will turn over a card and solve a problem. The highest card wins!
The practice worksheet asks students to solve 12 addition or subtraction problems. They must show their work and circle their answer.

For homework, which is structured in the same way as the practice worksheet, students will solve 12 addition or subtraction problems. They must show their work and circle their answer.
This lesson plan includes answer keys for the practice worksheet and homework. If you choose to manage lesson pages for your students via a PDF file, you will need to save a new file that deletes these pages. Otherwise, you can simply print out the appropriate pages and keep them as a reference for yourself when grading assignments.
