I use this tool with students who are struggling with adding and subtracting fractions with unlike denominators.  In the beginning this can be an overwhelming task for many students.  I have found that this tool can help those struggling students build their confidence.At this point there are students who need help generating their equivalent fractions, this tool can help.  Students often struggle in keeping their thinking or work organized, again this tool can help.  The work on the tool is also set up to help students see that they need to multiply the numerator and denominator by the same number.  Students will see that the multiplier is 2/2, 5/5, or 7/7.  So the tool also helps reinforce the idea that these fractions are equivalent because they are multiplying them by 1, 2/2 = 1.Laminate the worksheet so students can use it as often as they need it.

This task asks students to use two different denominators to subtract fractions. The purpose of this is to help students realize that any common denominator will work, not just the least common denominator.
