Review of Fractions: Equivalence and Comparison

Active learning works well for fractions because students often struggle with abstract symbols alone. When they manipulate physical or visual models in activities like Manipulative Matching or Paper Folding, they build strong mental images of equivalence and size. This hands-on work turns confusion about denominators into clear understanding through repeated, meaningful practice.

Activity 01

• 30 min · Pairs

Manipulative Matching: Equivalent Fractions

Provide fraction strips or printed bars representing fractions like 1/4, 2/8, 3/12. Students in pairs match equivalents by aligning strips to show equal lengths, then simplify by grouping units. Discuss findings as a class.

Analyze how common denominators facilitate the comparison of fractions.

Facilitation Tip

During Manipulative Matching, circulate with fraction tiles and ask pairs to explain why two fractions match before they record the pair.

What to look for

Present students with three fractions: 2/5, 4/10, and 3/7. Ask them to identify which fractions are equivalent and to explain their reasoning. Then, ask them to simplify 6/9 to its lowest terms.

Activity 02

• Stations Rotation
• 45 min · Small Groups

Stations Rotation: Comparison Strategies

Set up three stations: visual shading for like denominators, benchmark fractions on number lines, and cross-multiplication cards. Small groups rotate, solving five problems per station and recording strategies used.

Justify why 1/2 is equivalent to 2/4 using visual models.

Facilitation Tip

In Station Rotation, place a timer at each comparison station so students practise both methods without rushing but with focus.

What to look for

Give each student a card with two fractions, such as 5/8 and 7/12. Ask them to write down the steps they would take to compare these two fractions and determine which is larger. They should also state the common denominator they would use.

Game Show: Simplify and Compare

Divide class into teams for a buzzer game with fraction cards. Teams simplify first, then compare pairs using chosen strategies. Award points for correct justifications with drawings.

Differentiate between proper, improper, and mixed fractions and their representations.

Facilitation Tip

For Game Show, prepare a mix of simple and tricky fractions so all students experience both success and the need to revise their thinking.

What to look for

Pose the question: 'Why is it easier to compare 1/3 and 2/3 than it is to compare 1/3 and 1/4?' Facilitate a class discussion where students explain the role of the common denominator in making comparisons straightforward.

Paper Folding: Fraction Types

Each student folds A4 paper to create proper, improper, and mixed fractions, labels them, and converts between types. Share models in pairs to verify conversions.

Analyze how common denominators facilitate the comparison of fractions.

Facilitation Tip

With Paper Folding, insist students label each fold clearly to avoid confusion between halves, fourths, and eighths.

What to look for

Present students with three fractions: 2/5, 4/10, and 3/7. Ask them to identify which fractions are equivalent and to explain their reasoning. Then, ask them to simplify 6/9 to its lowest terms.

A few notes on teaching this unit

Teachers should start with concrete models before moving to symbols, as research shows this reduces errors in comparison tasks. Avoid rushing to rules; instead, let students discover patterns through guided play. Use small group discussions to surface misconceptions early, and repeat key activities like Simplify and Compare to build fluency. Always connect visual work back to the symbolic form to strengthen symbolic reasoning.

Successful learning looks like students confidently identifying equivalent fractions, simplifying without hesitation, and comparing unlike fractions using both methods. They should explain their reasoning clearly and use models or diagrams to justify their answers. Group discussions should show they can correct each other’s mistakes with evidence from their work.

Watch Out for These Misconceptions

• During Manipulative Matching, watch for students who pair 1/3 with 1/6 because both have small denominators, ignoring that 1/3 is larger.

  Have them place both fractions on a number line strip to see the actual size difference and ask them to find equivalents of 1/3 that match 2/6 or 3/9 to correct the error.

• During Station Rotation, listen for students who say 2/5 and 4/10 are not the same because the numbers look different.

  Ask them to overlay fraction tiles or strips to see that both cover exactly half the same whole, then guide them to write the multiplication step that shows 2 x 2 = 4 and 5 x 2 = 10.

• During Paper Folding, notice students who fold a paper into 3 parts and label each as 1/3 but think the pieces are smaller than halves.

  Have them fold another sheet into halves and thirds and compare the sizes side by side, then ask them to write improper fractions like 4/3 to show that fractions can be larger than 1.
