Activity 01
Pairs: Fraction Strip Matching
Provide pre-cut fraction strips for halves, thirds, and quarters. Pairs match equivalent strips by length and shade regions to represent 1/2 or 2/4. Discuss why different strips look unequal but represent the same fraction. Conclude with students creating their own strip sets.
Explain how a fraction represents a division of a whole.
Facilitation TipDuring Fraction Strip Matching, circulate and ask pairs to explain why the same fraction looks different when the whole changes size.
What to look forProvide students with a rectangle divided into 8 equal parts. Ask them to shade 3 parts and write the fraction represented. Then, ask them to explain what the denominator tells them about the rectangle.

Activity 02
Small Groups: Pizza Fraction Challenge
Groups receive paper circle pizzas divided into 6 or 8 slices. They shade fractions like 3/8 and describe using numerator and denominator. Compare with rectangular models cut from grid paper. Rotate roles for shading, explaining, and checking.
Compare different visual models for representing fractions.
Facilitation TipIn Pizza Fraction Challenge, listen for students to justify their portion sizes using terms like 'equal shares' and 'whole divided into.'
What to look forDisplay three different visual models of fractions (e.g., a shaded circle, a shaded bar, a set of colored counters). Ask students to write down the fraction each model represents and identify which model shows the largest fraction.

Activity 03
Whole Class: Visual Fraction Hunt
Project images of shapes and sets. Class identifies and constructs fractions verbally, then draws on mini-whiteboards. Teacher circulates to prompt comparisons between circle and bar models. End with a class fraction wall display.
Construct a fraction to describe a part of a given set or shape.
Facilitation TipFor Visual Fraction Hunt, prompt students to note how the same fraction appears in varied contexts, like circles and rectangles.
What to look forPose the question: 'If a pizza is cut into 6 equal slices and you eat 2, what fraction of the pizza did you eat? What if the pizza was cut into 8 slices and you ate 2? Which situation means you ate more pizza?' Facilitate a discussion comparing the fractions and visual representations.

Activity 04
Individual: Set Model Creator
Students draw sets of 12 objects, like apples, and shade to show 5/12. Label and compare with a partner briefly. Extend to converting between set and area models on the same page.
Explain how a fraction represents a division of a whole.
Facilitation TipWith Set Model Creator, remind students to count total objects first before naming the fraction they selected.
What to look forProvide students with a rectangle divided into 8 equal parts. Ask them to shade 3 parts and write the fraction represented. Then, ask them to explain what the denominator tells them about the rectangle.

Generate Complete Lesson→A few notes on teaching this unit
Teach fractions by starting with real-world objects students can touch and see, like paper pizzas or counters. Avoid rushing to symbols until students can verbally describe what 3/4 means in multiple contexts. Research shows that students who build their own models retain fraction sense longer than those who only observe pre-made diagrams. Use peer talk to surface misconceptions early, especially around improper fractions and unit fractions.
Successful learning is visible when students confidently explain how the numerator and denominator relate to shaded regions in models. They should compare fractions by size rather than by number of parts, and articulate why equivalent fractions hold the same value across different visual forms.
Watch Out for These Misconceptions
During Fraction Strip Matching, watch for students who assume fractions always represent parts less than one whole.
Have students extend strips beyond the one-whole mark to build improper fractions like 5/4, then ask them to explain how the strip shows a whole plus an extra fourth.
During Pizza Fraction Challenge, watch for students who believe a larger denominator means a larger fraction.
Direct students to compare 1/2 and 1/3 with identical pizza sizes, shading each slice and discussing which piece is bigger relative to the whole.
During Set Model Creator, watch for students who think equivalent fractions must look identical.
Ask students to overlay 2/4 and 1/2 using counters to see that different arrangements can represent the same value, focusing on proportion, not appearance.
