# Best Tips & Tricks for Fractions Homework

Jan 10, 2024When it comes to working with fractions, you can never have enough tricks up your sleeve. Whether it is a way to help your students remember the correct order of several steps to solve a confusing problem, or just a trick that provides a less complicated way of doing things, we’ve got you covered!

**Cross Multiply UP**

**Trick to Use for Comparing Fractions **

Students learn how to compare fractions beginning in the 3rd grade and this skill is also a significant part of the 4th grade curriculum. They learn *several* different strategies to compare fractions under different circumstances, but there is one strategy that is simple, easy to remember and can be used to compare *any* two fractions: Cross Multiply Up! You can see this strategy (and others) in action along with step-by-step instructions on how to use it in our FREE Ultimate Guide to 3rd Grade Fractions.

**The Butterfly Method**

**Use this Trick to Add and Subtract Fractions That Do Not Have the Same Denominators**

In 5th grade students learn to add and subtract fractions with unlike denominators. They learn how to solve these problems by renaming the fractions as fractions with common denominators (which is an extremely important strategy to learn and master). However, when the fractions of these problems contain numerators and denominators that are *12 or less*, the Butterfly Method is a cool shortcut to arrive at the same answer. You *can *use this trick on fractions with numerators and denominators greater than 12, however doing so usually results in much larger answers that are harder for students to put in simplest form. We provide all you need to know about the Butterfly Method along with how to solve these problems by finding common denominators in our FREE Ultimate Guide to 5th Grade Fractions.

**Keep, Change, Flip (KCF)**

**Remember this Saying or Acronym to Help You Divide Fractions**

Students begin to learn how to divide fractions in 5th grade usually with dividing a whole number by a fraction or a fraction by a whole number. In 6th grade they expand this skill and learn how to solve problems dividing different combinations of fractions and mixed numbers. Students are taught that when dividing by a fraction, to solve the problem by using reciprocals or multiplicative inverses. This translates into multiplying the dividend by the reciprocal of the divisor. Make sense? Maybe, but a much EASIER way to say this is Keep, Change, Flip! *Keep* the first term the same, *Change *the division symbol to a multiplication symbol, and *Flip* the second term. We have explained this strategy and others in detail along with guided example problems in our FREE Ultimate Guide to 5th Grade Fractions AND our FREE Ultimate Guide to 6th Grade Fractions. You're welcome :-)

**Divisibility Rules**

**Use These Hacks to Help You Simplify Fractions That Have Larger Numbers for the Numerator and Denominator**

Usually in 4th grade students are introduced to a set of *Divisibility Rules* to help them identify factors of larger numbers. For example, do you know if you can evenly divide 270 by 6? or is 834 divisible by 3 or 8? If you know these rules or have them on hand to reference, you can easily answer these questions. In 4th, 5th and 6th grades, students are required to write fractions in simplest form using division. If they have a fraction such as 468/30 that they are trying to put in simplest form, finding the largest number that they can divide both 468 and 30 by can seem very intimidating. Check out how these divisibility rules provide a simple solution for a complicated task in our FREE Ultimate Guide to 5th Grade Fractions AND our FREE Ultimate Guide to 6th Grade Fractions.
