Mix things things up in your elementary math class with a series of problem-solving exercises. Presented with a series of mixed number word problems, young mathematicians are asked to solve them by using either visual fraction...

Two visual problems give mathematicians a chance to compare fractions with like denominators. They examine two pairs of shapes with portions filled in, adding the greater than, less than, or equal to symbol between each. The shape pairs...

Compare fractions  with these visual examples, all of which have like denominators. There are five pairs of shapes here with various portions shaded. Each pair is segmented into the same number of sections, so comparing is much...

View this presentation, which introduces the concepts of fractions, the parts of fractions, how to subract fractions with common denominators, and how to simplify the answers into lowest terms with your class. Use for an introduction or...

Explore the concept of adding fractions with like denominators. Your visual and logical learners will gain a comfortable understanding of this concept, as each slide contains an example and steps that are clearly explained. Several...

Enjoy these straightforward and simple worksheet pages that practice with different denominators. The practice starts simple with adding fractions together and then works on a recipe that needs to be tripled. 

If the fractions don't have a common denominator, make them have one. Learners first read and analyze a conversation of pupils trying to add 2/5 and 1/2. They compare the process of adding fractions to the process of adding quantities...

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 compare two fractions with like denominators and then move to the next level to compare fractions with unlike denominators. They will first try to use mental math to make educated guesses. There are a few guidelines...

Designed as a quiz for your elementary mathematicians, this resource contains 17 problems. The first 15 problems involve adding and subtracting fractions with like denominators, while the last two problems are word problems. Your...

Learners are asked to find multiples and common multiples of two numbers. They must take their findings and find a pattern between the numbers and explain their reasoning. Use this resource with The Florist Shop activity in this series...

In this mixed number addition learning exercise, students add the whole numbers and then the fractions in the mixed number equations. Students then reduce the fraction to solve the 14 problems.
