Make It Work! Adding Fractions with Unlike 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.
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.
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.
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.
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.
Help students color-code their way to multiplying fractions! Students will learn how to multiply fractions using area models. Use this lesson on its own or use it as support to the lesson Area Models and Multiplying Fractions.
In order to build a strong foundation with fractions, students should be able to explain the concept and their thinking. Use this as a stand alone lesson or as a pre-lesson for *Let's Play Equivalent Fractions!*
“Subtract One” Strategy: Subtracting From Zeros Without Borrowing
Many students cringe when they see a subtraction problem with multiple zeros. The “Subtract One” strategy in this lesson involves reducing the top number by one to turn the 0 digits into 9’s and then adding the one back in at the end.
