Showing Results for with the different denominators

Increase your students' knowledge of fractions with this lesson that has them compare fractions with different denominators. 

Making Models with Different Denominators

Getting ready to subtract fractions? This lesson reviews how to subtract like denominators and teaches students how to subtract unlike denominators. The focus is on understanding the process and reasoning behind each step.

Subtracting Fractions with Different Denominators

Adding fractions with unlike denominators just doesn't work like it does when the denominators are the same. Let's make it work! Students will add fractions with unlike denominators with sums between one and two.

Make It Work! Adding Fractions with Unlike Denominators

Give your students the opportunity to explore the perspectives of different characters by using the "Circle of Viewpoints" Visible Thinking Routine from Harvard's Project Zero.

Exploring Different Perspectives in Folktales

Challenge your students to compare two methods for finding the least common multiple between two fractions. Use this lesson on its own or as support for the lesson Make It Work! Adding Fractions with Unlike Denominators.

Compare Common Denominators Methods

Are the stories the same or different? You decide! Use this lesson with your students to practice comparing the story elements in two fictional stories written by the same author. 

The Same or Different? You Decide!

In this hands on lesson, students create squares with different fraction pieces while building their knowledge of adding fractions with different denominators.

Building Squares

Continue to build on your students' understanding of unlike denominators by asking students to justify their answers of fraction subtraction. Use this lesson with the Subtracting Fractions with Different Denominators lesson.

Subtracting Fractions Justifications

How are plants’ traits affected by environmental factors? In this integrated science and reading lesson, students will use multiple sources to identify and determine how traits are influenced by the environment.


What’s Similar? What’s Different?

The activities in this lesson will engage students in thinking about how a person’s position, needs, and concerns affect their point of view on an issue. Students will apply this to characters in "The Memory String" by Eve Bunting.

Exploring Different Points of View

Does chaos ensue when your students subtract like mixed numbers and the larger fraction has a lesser numerator? Using this lesson plan, teach your class how to overcome this tricky obstacle: When having like denominators isn’t enough! 

When Having Like Denominators Isn’t Enough!

Using your acting skills and a great book by Chris Van Allsburg, you will lead your students on an adventure to compare characters and events throughout a book.

What's So Different? Comparing Characters

Help kids master fractions with the fun, fast-paced, math comparison game Fraction Wars. After a review, students are split into pairs to practice quickly comparing fractions with different numerators and denominators.

Fraction Wars

Help your students show their understanding as they explain how to add fractions with unlike denominators. Use this lesson on its own or as support to the lesson Make It Work! Adding Fractions with Unlike Denominators.

Explaining Fraction Addition

Getting ready to add fractions? This lesson reviews how to add fractions with unlike denominators using number lines. Students will focus on understanding the process and reasoning behind each step.

Adding Fractions on Number Lines

In this lesson, students will explore fractions with the same denominators and work as mathematicians to figure out patterns. Your students will gain a lot of practice in comparing fractions!

Comparing Fractions with the Same Denominator

It's time to zoom in on the space between 0 and 1 on the number line! In this lesson, your students will get practice labeling different fractions on the number line.

Number Line Time

When fractions have big numerators and denominators, it can be tough to find the simplest form. Fear not! Use this lesson plan to teach your students to find the simplest form using the greatest common factor. 

Fraction Simplest Form by Greatest Common Factor
