Equivalent Fractions (Simple Cases)Activities & Teaching Strategies
Active learning helps students visualize that different fractions can represent the same amount, moving beyond symbols to concrete understanding. Third-year students need to see, touch, and compare fractions to build lasting comprehension of equivalence rather than memorize rules.
Learning Objectives
- 1Identify pairs of simple equivalent fractions using visual fraction models.
- 2Design a visual model to demonstrate the equivalence of two simple fractions, such as 1/2 and 2/4.
- 3Compare two simple equivalent fractions and justify their equality by referencing their visual representations.
- 4Explain why two fractions that look different can represent the same portion of a whole.

Manipulative Matching: Fraction Strips
Provide pre-cut strips for 1/2, 2/4, 1/3, 2/6. Students lay strips side-by-side on a mat to match equivalents by aligning shaded lengths. Groups record pairs and explain matches to the class.
Prepare & details
Explain how two different looking fractions can represent the same amount.
Facilitation Tip: During Manipulative Matching, remind students to align fraction strips carefully to see identical lengths for equivalent fractions.
Setup: Wall space or tables arranged around room perimeter
Materials: Large paper/poster boards, Markers, Sticky notes for feedback
Paper Folding: Equivalent Shares
Each student folds A4 paper into halves, then refolds into quarters. Shade 1/2 and overlay on 2/4 to compare. Pairs swap papers to verify and label equivalents.
Prepare & details
Design a visual model to show that 1/2 is equivalent to 2/4.
Facilitation Tip: For Paper Folding, encourage students to fold slowly and press creases sharply to maintain equal partitions.
Setup: Wall space or tables arranged around room perimeter
Materials: Large paper/poster boards, Markers, Sticky notes for feedback
Circle Models: Pizza Slices
Draw circles as pizzas. Divide one into 2 equal parts and shade 1; divide another into 4 and shade 2. Students compare areas, then create models for 1/3 and 2/6. Share justifications in whole class.
Prepare & details
Compare different equivalent fractions and justify their equality.
Facilitation Tip: When using Circle Models, have students color the same amount on each pizza slice to reinforce equal portions.
Setup: Wall space or tables arranged around room perimeter
Materials: Large paper/poster boards, Markers, Sticky notes for feedback
Sorting Relay: Fraction Cards
Prepare cards with visuals of 1/2, 2/4, etc. Teams race to sort equivalents into piles at stations, then verify with strip models. Discuss errors as a group.

Teaching This Topic
Experienced teachers approach this topic by starting with concrete models before moving to abstract symbols, as research shows this builds stronger foundational understanding. Avoid rushing to numerical rules; instead, let students discover equivalence through hands-on exploration. Emphasize the importance of the whole remaining consistent across all models to prevent misconceptions about fraction size.
What to Expect
By the end of these activities, students should confidently identify and justify equivalent fractions using visual models and manipulatives. They should explain why fractions like 1/2 and 2/4 are equal by comparing shaded areas and describing the whole uniformly.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring Manipulative Matching, watch for students who believe 2/4 is larger than 1/2 because the numerator 2 is bigger than 1.
What to Teach Instead
Prompt students to lay the 1/2 and 2/4 fraction strips side by side and observe that they cover the same length. Ask them to measure and compare the shaded parts directly to see the equivalence.
Common MisconceptionDuring Sorting Relay, watch for students who think fractions are equivalent only if numerator and denominator match exactly.
What to Teach Instead
During the relay, pause to have students explain why a fraction card with 1/2 fits with a card showing 2/4. Ask them to point to the shaded areas in their models to justify the match.
Common MisconceptionDuring Paper Folding, watch for students who believe more parts in the denominator always means a smaller fraction.
What to Teach Instead
Have students fold paper into halves and then into fourths, shading 1/2 on both. Guide them to compare the shaded areas and see that 1/2 and 2/4 cover the same amount despite different numbers of parts.
Assessment Ideas
After Manipulative Matching, provide students with pre-drawn fraction strips. Ask them to shade 1/3 on one strip and then shade an equivalent fraction on a second, identical strip, labeling both fractions. Observe if they correctly shade 2/6.
During Circle Models, present students with two different visual models showing 1/2 and 2/4. Ask: 'How do these models show that the fractions are the same amount? What would you tell someone who said 1/2 and 2/4 are different amounts?'
After Sorting Relay, give each student a card with a fraction, for example, 3/4. Ask them to draw a visual model to represent this fraction and then draw a second model showing an equivalent fraction, writing the equivalent fraction below their drawing.
Extensions & Scaffolding
- Challenge students to find three different fractions equivalent to 3/4 using fraction strips, then record their findings in a table.
- For strugglers, provide pre-partitioned fraction circles with one fraction already shaded and ask them to shade the equivalent.
- Deeper exploration: Introduce real-world contexts like recipes or measurements where equivalent fractions are used, asking students to create their own examples.
Key Vocabulary
| Equivalent Fractions | Fractions that represent the same value or amount, even though they have different numerators and denominators. For example, 1/2 and 2/4 are equivalent. |
| Numerator | The top number in a fraction, which indicates how many parts of the whole are being considered. |
| Denominator | The bottom number in a fraction, which indicates the total number of equal parts the whole is divided into. |
| Fraction Model | A visual representation, such as a shaded rectangle, circle, or fraction strip, used to show a fraction or compare fractions. |
