Fractional Metric Measurements on a Line Plot

It falls between 0 and 1.

The segment is divided into 3 equal parts.

$\frac{2}{3}$ is placed just two parts from 0, closer to 1 than to 0.

It falls between 2 and 3.

The segment is divided into 4 equal parts.

$2 \frac{1}{4}$ is placed one part past 2, indicating it is a quarter way from 2 to 3.

$\frac{1}{2}$ is placed exactly halfway between 0 and 1.

$3 \frac{3}{5}$ is placed three and three-fifths units from 0, close to 4.

$\frac{5}{8}$ falls slightly past the halfway point between 0 and 1, close to $\frac{3}{4}$.

$1 \frac{1}{3}$ is positioned one and one-third units from 0, just over the mark of 1.

$\frac{3}{4}$ is three-quarters of the way from 0 to 1, closer to 1 than to $\frac{1}{2}$.

A fraction represents a part of a whole, expressed as a quotient of two numbers—the numerator and the denominator.

Placing fractions on a number line helps visually compare their sizes and understand their values relative to whole numbers.

Identify the whole numbers it falls between, divide the segment into equal parts based on the denominator, and place the fraction accordingly.

Locate the whole number on the line, then add the fractional part as if starting from that whole number.

Yes, a number line allows for easy comparison of fractions by visual inspection of their positions relative to each other and to whole numbers.

If two fractions are at the same point, they are equivalent, meaning they represent the same portion of a whole despite possibly having different numerators and denominators.

The denominator determines how many equal parts the segment between two whole numbers is divided into. Larger denominators mean more divisions, placing the fraction closer to one of the whole numbers.

While this lesson focuses on positive fractions, negative fractions can also be placed on the number line, to the left of zero.

This visual tool helps students grasp the concept of fractions, compare their sizes, and understand their arithmetic operations more intuitively.

Examples include measuring ingredients in cooking, determining distances, and calculating time intervals.
