Subtract Fractions


Subtract Fractions teaches students how to subtract a fraction that contains 10, 100, and 1000 as the denominator. Students will learn two methods they can use to convert the denominators easily. The worksheets will provide them with plenty of opportunity to practice.

There are a few suggestions listed on the “Options for Lesson” section that you could use in your class. One suggestion is to have students create their own Bump game boards using various questions. They will use what they learned during the activity to create their own boards. Another options is for advanced students. You could increase the number of place values or decrease it and use decimals.

What our Subtract Fractions lesson plan includes

Lesson Objectives and Overview: Subtract Fractions teaches students how to subtract fractions with 10, 100, and 1000 as denominators. They will learn how to convert fractions to the proper denominator using a couple techniques. By the end of the lesson, they will be able to solve fractional problems with these denominators.

The lesson contains two content pages. The first page reminds students that they must have a common denominator if they want to subtract fractions. You can spend extra time explaining this concept if you need to. The lesson then describes a couple ways to create a common denominator. There are several examples that students can practice with. You could also provide extra examples if students need a little extra help.


Students will work with a partner for the activity. The worksheet displays 11 boxes with various fraction equations. The 11 spaces correspond to the sum of two die. The first student will roll the die, and the second student will find the problem and solve it.

They will use a board with the numbers that correspond to the correct answers. They will also have counters that they can place on the appropriate numbers when they get it right. If the other person’s counter is on the space with the right number, they can bump it off and replace it with their own counter. If it has their own counter, they can place the second counter on that space. Then, if the other player gets that number, they cannot bump the other players’ counters. The game ends when all of one student’s counters are on the game board.


The practice worksheet has two sections. The first section requires students to fill in the table with equivalent fractions. The second section requires them to convert fractions to the same denominator and then subtract the fractions.


The homework assignment is similar to the practice worksheet. Students will fill in a table with equivalent fractions. Then they will convert fractions to the same denominator and subtract the fractions.


For the quiz, students will answer two questions and show their work.
