TEKS 3.3F: Equivalent Fractions Representation
Recognize Equivalent Fractions Using Number Lines
About this lesson
Learning Target: I can represent equivalent fractions using number lines.
Focuses On:
- Partitioning number lines into equal parts
- Using double number lines to identify and represent equivalent fractions
- Using common denominators to create equivalent fractions on a number line (ie. splitting halves into fourths and fourths into eighths)
Builds On:
2.3A:
Partition objects into equal parts and name the parts, including halves, fourths, and eighths, using words.
Next Level:
4.3C:
Determine if two given fractions are equivalent using a variety of methods.

This lesson is designed to build on the foundational understanding of partitioning objects into equal parts to represent fractions.
The three instructional blocks in this lesson focus on halves, fourths and eighths, thirds and sixths, and mixed denominators.
In the first instructional block, students use double number lines to identify and represent halves, fourths and eighths. The number lines help students visualize that fractions can land on same place on a number line, even if their denominators are different.
The second instructional block students use the same strategies in the first block except with thirds and sixths.
The third instructional block focuses on having students use number lines to identify equivalent fractions with mixed denominators.
Supported expressions and multiple strategies are intentionally built into the lesson to scaffold student understanding.

About this lesson
Learning Target: i can represent equivalent fractions using models.
Focuses On:
- Utilizing shaded fraction circles to quickly represent and understand equivalent fractions
- Using fraction strips to line up equivalent fractions
- Identifying equivalent fractions using other models

This lesson is designed to build on foundational understanding of partitioning shapes into equal parts to represent fractions. It builds a bridge between using fraction models and seeing equivalent pieces shaded within those models to represent the same value.
The three instructional blocks in this lesson focus on equivalent fractions-one half, equivalent fractions-fraction strips and equivalent fractions-models.
In the first instructional block, students use fraction circles to represent one-half with equivalent fractions.
The second instructional block focuses on equivalent fractions that are represented in fraction strips.
The third instructional block focuses on having students identify equivalent fractions using other pictorial models
Pictorial representations, models and supported expressions are intentionally used throughout the lesson to scaffold student understanding.
