Purpose

Students investigate how fractions describe real-world parts of a whole and how those parts can be compared using hands-on paper models. Working in pairs, they build and revise fraction strips, circles, and rectangles to show unit fractions, place fractions on number lines, and compare fractions with the same numerator or denominator. The experience leads to a wall-ready paper project and classroom gallery walk that help students clearly communicate their mathematical thinking. Through partner feedback, daily reflection, and an end-of-week exit ticket, students strengthen content understanding, collaboration, and confidence in explaining fractions.

Learning goals

Students will model unit fractions and non-unit fractions using paper strips, circles, and rectangles to show halves, thirds, fourths, sixths, and eighths, and place those fractions on number lines. They will compare fractions with the same numerator or the same denominator by building matching paper models and explaining which fraction is larger or smaller using clear math language. Working with a partner, students will revise their models after peer checks and create a paper display for a classroom gallery walk that clearly shows fraction equivalence and comparison. Students will reflect at the end of each class on how well their project communicates their thinking and what they will improve next.

Standards
  • [Common Core] CCSS.Math.Content.3.NF.A.3 - Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size.
  • [California] 3.NF.A.3 - Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size.
  • [California] 3.NF.A.2 - Understand a fraction as a number on the number line; represent fractions on a number line diagram.
  • [Common Core] CCSS.Math.Content.3.NF.A.2 - Understand a fraction as a number on the number line; represent fractions on a number line diagram.
  • [Common Core] CCSS.Math.Content.3.NF.A.1 - Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts; understand a fraction a/b as the quantity formed by a parts of size 1/b.
Competencies
  • Effective Communication - Students practice listening to understand, communicating with empathy, and share their learning through exhibiting, presenting and reflecting on their work.
  • Collaboration - Students co-design projects with peers, exercise shared-decision making, strengthen relational agency, resolve conflict, and assume leadership roles.
  • Critical Thinking & Problem Solving - Students consider a variety of innovative approaches to address and understand complex questions that are authentic and important to their communities.
  • Content Expertise - Students develop key competencies, skills, and dispositions with ample opportunities to apply knowledge and engage in work that matters to them.
  • Academic Mindset - Students establish a sense of place, identity, and belonging to increase self-efficacy while engaging in critical reflection and action.

Products

Students create a partner-made paper fraction display that uses strips, circles, and rectangles to show halves, thirds, fourths, sixths, and eighths, with labeled models placed on number lines. Throughout the week, they also produce station recording cards and revised comparison models that show which fractions are larger or smaller when they have the same numerator or denominator. The final product is a wall-ready poster or collage that clearly explains fraction equivalence and comparison with visuals, math language, and examples from everyday life. These products are designed for an in-class gallery walk and support a final fraction exit ticket at the end of the week.

Launch

Begin with a Fraction Match-Up Challenge in pairs, where students rotate through quick stations using paper strips, circles, and rectangles to build halves, thirds, fourths, sixths, and eighths. At each station, partners decide which fraction is larger or smaller by comparing models with the same numerator or same denominator, then record their thinking with simple drawings or labels. Close the launch with a brief whole-class share of surprising matches and introduce the challenge of creating a paper fraction display for a classroom gallery walk by the end of the week.

Exhibition

Host an in-class gallery walk where each pair displays their hanging paper fraction project with fraction strips, circles, and rectangles showing halves, thirds, fourths, sixths, and eighths. Students stand by their work to explain how they compared fractions with the same numerator or denominator and point out one revision they made after partner feedback. Classmates rotate with simple response prompts such as “I notice…” and “I wonder…” and complete a quick exit ticket on comparing fractions by the end of the week. Close with a short celebration circle where partners share what part of their project shows fractions most clearly and what they learned about larger and smaller fractional parts.
