This requires either a good number sense or a lot of experience. The key to using this method for comparing fractions is identifying a benchmark fraction for comparison. The goal is to provide examples for comparing two fractions, $rac. It is easy to use and helps us to make sense of the numbers What fraction with a.

If the numerator is almost half of the denominator, then we round the given fraction to 1 2. If the numerator is much smaller than the denominator, we round the given fraction to 0 Example: 1 9, 1 5 can be.

Note: The one whole and two half strips are included for reference. Use benchmark fractions and number sense of fractions to estimate mentally and assess the reasonableness of answers. Today's resource supports the following Common Core State Standard for Math:ĥ.NF.A.2- Solve word problems involving addition and subtraction of fractions referring to the same whole, including cases of unlike denominators, e.g., by using visual fraction models or equations to represent the problem.

#Using benchmark fractions how to

See the examples below of how to use fraction strips to compare to a benchmark. Students need lots of opportunities to make the comparisons using fraction tools before being able to make a visual estimation from the formal notation. When students show that they are proficie. It's important to note that students don't just develop this understanding without beginning with the conceptual models. Comparing Fractions Using Benchmarks Fractions Games A strong foundation in maths is built when a child has sensible knowledge of various kinds of math problems. This video demonstrates how to use benchmark fractions, such as 1/2, to compare fractions with unlike denominators. Two-sixths is closer to zero, not one whole.)

#Using benchmark fractions plus

(An understanding that prevents the dreaded one-third plus one-third equals two-sixths because using benchmark fractions will allow students to see that one-half plus one-half equals one whole. It took some time, but I began to notice that my students' understanding of fractions developed into the deeper understanding I had envisioned. Each time I presented a fraction, I posed the question, 'Is this fraction closer to zero, one-half, or one whole?' And, I often added, 'How do you know?' A few years back, in an effort to try to help my fourth graders really make connections between the value of a fraction and the formal fraction notation, I taught them how to compare the fraction to a benchmark. For some reason, students struggle to understand how to make sense of the value of a fraction.

We all know that fraction concepts have plagued our students for many years. This week, I want to talk about using benchmark fractions to better help students make connections between the value of the fraction and the formal fraction notation. Last week, I discussed how to use fraction tools to help students learn to connect a fractional part to the whole and then to the formal fraction notation.
