In this math instructional activity, students practice combining the fractions with unlike denominators. They find the common denominators before writing equivalent fractions to solve.

In this fraction worksheet, students add and subtract fractions with unlike denominators.  They multiply and divide fractions.  This one-page worksheet is designed for mental math.  It contains 30 problems, with answers.

In this fraction worksheet, students subtract fractions with unlike denominators.  This one-page worksheet contains 24 problems.

In this math activity, students subtract the fractions using unlike denominators. The answers are used for the coded message at the bottom of the page.

For this math worksheet, students solve 10 problems in which fractions and mixed numbers with unlike denominators are added and subtracted. Every problem has 3 numbers to be both added and subtracted. Denominators are often two digits.

In this fractions worksheet, students solve 10 problems in which three fractions or mixed numbers with unlike denominators are added.

Students explore why denominators need to match before adding (or subtracting) a fraction. They use unmarked fraction circles and marked fraction bars, to discover a method to add fractions with unlike denominators using equivalent...

Seventh graders add and subtract fractions with like and unlike denominators. After discussing the use of fractions in the real world, 7th graders work problems and draw models representing each problem. They observe subtracting...

This worksheet is a mix of 24 problems on adding and subtracting rational expressions. All of the problems have unlike denominators. Most require factoring of the denominators, and a few contain mixed expressions and three expressions....

In this adding and subtracting rationals instructional activity, students find common denominators and solve 26 computation problems. Denominators are polynomials and fractions.

An answer key is included with this fraction review assignment. In it, fractioniers simplify large fractions, convert mixed numbers to improper fractoins, and change improper fractions into mixed numbers. Though the publisher states that...

Students solve fractions using multiplication, subtractions and division. In this algebra instructional activity, students use the correct steps to solve fractions with unlike denominators when addin g and subtracting. They solve...

Fifth graders practice using the English measuring system by creating fractions.  In this parts of a whole lesson, 5th graders combine math key bars to simulate small parts of a bigger item.  Students combine the pieces to...

In this subtraction of mixed numbers with unlike denominators, 6th graders solve eight columns of ten vertical subtraction problems plus two review problems at the end of each column.

This unit on fractions allows for upper-aged elementary learners to explore ways to find the greatest common factor and least common multiple of two numbers. Ultimately, young mathematicians will be able to identify equivalent fractions,...

Now that the practice is over, see if young mathematicians can utilize their new skills on finding common denominators and adding fractions. The assessment contains one map challenge and follows with skills practice. 

Students use Cuisenaire rods to explore common denominators. In this fractions lesson, students build Cuisenaire representations of fractions, then find their equivalent counterparts to find the common denominator.

Young mathematicians research and discuss real world math word problems and ways in which they apply math concepts in their everyday lives. They create a storyboard of a math word problem from which they create a slide for a multi-media...

In this summer school math worksheet, students complete 100 multiplication problems in which 3 digit numbers are multiplied by 2 digit numbers. Students also solve 100 problems in which simple fractions with unlike denominators are added...

Both a reference sheet and skills practice worksheet, this handout on common fraction rules reviews steps for adding, subtracting, multiplying, and dividing fractions. Twenty examples are provided to demonstrate these skills, and...

For this inequality worksheet, students solve inequality equations and graph the solution on a number line. They add and subtract fractions with variables and unlike denominators. Students solve absolute variable equations with one...

Test your scholars' knowledge of a multitude of concepts with an assessment aligned to the California math standards. Using the exam, class members show what they know about the four operations, positive and negative numbers, statistics...

In this fraction subtraction instructional activity, students show their work in spaces provided, completing a total of 5 subtraction problems. Answers are included on page 2.

Sixth graders solve and analyze fractions. In this algebra lesson, 6th graders solve fractions using addition, subtraction, multiplication and division. They work in groups and do peer-review.
