What Are Benchmarks In Fractions

What is a Benchmark Fraction?

In math, benchmark fractions tin exist defined equally mutual fractions that nosotros can measure out or judge against, when measuring, comparing, or ordering other fractions. Criterion fractions are easy to visualize and identify, and thus, assist in estimating the parts. When comparing two fractions with different numerators and denominators, we tin either make their denominators mutual or compare them to a benchmark fraction such as 1/2. Criterion fractions are most helpful when fractions to exist compared are placed on a number line against the benchmarks.

Here's a chart of benchmark fractions placed on a number line, which can assistance in comparing fractions.

Allow benchmark fractions exist your guiding action.
Just begin by putting the fractions on a number line.
T hen, choose the benchmark to compare – It'll be fine!

Before y'all hand out worksheets on comparing fractions, draw the benchmark fractions nautical chart on a chart newspaper. Give examples and model how the nautical chart can be used to compare and order fractions with dissimilar numerators and denominators. You may further give them newspaper and crayons to draw and represent the fractions to be compared.
