A math center or task cards practicing common core subtracting fractions using the butterfly method. The set contains 18 task cards with a butterfly and a fraction subtraction problem. Students need to solve the problem on each card and record the answer on one of the two different worksheets provided. One worksheet provides a place for the answer and the second version has butterflies so students can use the frame to guide the butterfly method. There is also a sheet showing the steps of the process for adding fractions with different denominators using the butterfly method.
The set is connected to common core standards and also includes an answer key.
