TEKS 2.3C: Fractional Parts
Fractional Parts with Models
About this lesson
Learning Target: I can name a fraction that is greater than one whole from a model.
Focuses On:
- Naming fractions: halves, fourths and eighths
- Using models to create improper fractions
- Using models to create mixed numbers
Builds On:
1.6G

Next Level:
3.3H
Compare two fractions having the same numerator or denominator in problems by reasoning about their sizes and justify the conclusion by using symbols, words, objects and pictorial models.

This lesson is designed to support student understanding of modeling fractions that are greater than one whole. The two instructional blocks in this lesson focus on improper fractions and mixed numbers.
In the first instructional block, students model and name fractions that are greater than one using improper fractions. First, students create a denominator through counting how many parts make up one whole. Then there is an opportunity to create a numerator by counting the shaded parts of a model. Modeling fractional parts through pictorial representations support student understanding of improper fractions.
The second instructional block focuses on using models to create mixed numbers by counting wholes and naming the equal parts. The pictorial representation of models greater than one support student understanding of mixed numbers.
Scaffolds and supports such as practicing how many parts make one whole are intentionally found throughout the lesson to support conceptual learning.
