![]() So, a known size or amount helps understand a different size or amount. How to compare fractions by using benchmarks and number lines?īenchmark fraction definition: A common fraction that we can use to compare other fractions is a benchmark fraction.How to compare fractions using benchmark fractions?.The word benchmark refers to a standard that other things can be compared to. Their role and usage are the same as their name suggests. Want to simplify comparing and ordering fractions? Learn all about benchmark fractions, their definition, use, chart, and much more, as it is one of the best strategies to use these fractions when understanding the comparison of fractions. It does not store any personal data.2/12 or 6/7- which one is greater? To answer this, one would have to calculate the lowest common denominator and then multiply both fractions so that they share a common denominator and then compare them. ![]() The cookie is set by the GDPR Cookie Consent plugin and is used to store whether or not user has consented to the use of cookies.

Checkout this blog post about how you can use fraction squares in your classroom and head to my Instagram to see some of these ideas in action! Hopefully this post helped give you some new ideas and strategies to support students in upper elementary with comparing fractions. Students have many options when comparing fractions! Limiting them to just one option does not give them the freedom and flexibility that they need in their thinking with fractions. For example, if students were comparing 6/8 and 2/6 they would notice that 6/8 is greater than 1/2 and 2/6 is less than 1/2, so 6/8 would be the larger fraction. Instead of taking the time to find a common denominator, students compare each fraction to a benchmark fraction. It shows that the student has deep understanding of a fraction if they can compare it to a benchmark fraction, such as 1/2. This is my favorite strategy to compare fractions in upper elementary. Area models provides a visual for students to use, which makes it easier. This is usually done as a prior step for students using multiplication to find equivalent fractions and then compare from there. Whichever area model has the most colored in squares is the bigger fraction. Then they find what the common denominator would be, and split each area model so they have the same number of total pieces. Students draw each of the fractions with their own area model. My favorite type of area models are using squares. Some of my favorite manipulatives for this are fraction tiles because it is easy for students to line up and compare. It is hands on as well as visual, so it will be very simple for students to see which fraction is greater. Using manipulatives is a great strategy to compare fractions in upper elementary and lower elementary. If you need ideas on how to introduce the importance of common denominators check out this blog post! This is a popular strategy for comparing fractions in upper elementary because they are finding equivalent fractions through multiplication often in order to add fractions, and this strategy supports that process. When two fractions have the same denominator, the fraction with the largest numerator is the bigger fraction. It is not always the most efficient process, but it will provide a very clear and obvious answer. This is a very popular strategy for comparing fractions in upper elementary! It supports students with finding equivalent fractions by using multiplication. What are some strategies for comparing fractions in upper elementary grades? This post will talk about four strategies to help you with this!
