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.
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.
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 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.
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!
Subtracting Mixed Numbers Using the Decomposition Strategy
Teach your students to subtract mixed numbers with like denominators using the strategy of decomposition. This strategy helps students to manipulate and break down numbers to help them solve tricky subtraction problems.
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.
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!*
