Subtracting Fractions- Butterfly Method

Class Experience
In this one-time 50 minute class, students will master the skill of subtracting fractions with unlike denominators. After taking this class, students will feel confident in their ability to subtract fractions with unlike denominators using the butterfly method. 

Class Outline 
Throughout the lesson, students will be encouraged to actively participate. The class will begin with a 5 minute ice-breaker. Ice-breakers are so important for building a supportive classroom community. The ice-breaker will allow students to feel more comfortable with me as their teacher as well as learn about their peers. Next, students will be given a real-life example of when it is necessary to subtract fractions with unlike denominators. Students will be encouraged to solve this subtraction problem using any method they may already know. This will allow me to gain insight into students' prior knowledge. Next, students will be guided through the steps on how to subtract two fractions using the butterfly method. Students will be encouraged but not required to simplify their answers. Class participates should leave the class feeling confident in their ability to calculate the difference between two fractions using this new method of algorithm. 

Recommended For:
If child needs a new strategy for subtracting fractions with unlike dominators, this course is for him/her! This course is recommended for students who are in 4th, 5th and 6th grade. 

Prior Knowledge:
Before taking this course students should have prior knowledge on subtracting fractions with like denominators. The methodology of subtracting fractions with like denominators will be reviewed briefly before the method for adding unlike denominators is introduced.
