Comparing and ordering fractions
Decide which fraction is bigger, and put fractions in order.
Planned. This module is part of the plan and is not written yet.
Why it matters
Is two thirds of a sack more than three fifths of the same sack? Comparing fractions tells you which share or which offer is bigger.

Inside the module.
5 lessons in order, about 60 minutes in all, then a short test. Learners go at their own pace; the minutes are a guide, not a timetable.
Draft outline · in review
Lesson 1: Same denominator
When the parts are the same size, more parts means a bigger fraction.
Explain10 min, from minute 0
Lesson 2: Same numerator
With the same number of parts, smaller parts mean a smaller fraction: 1/8 < 1/3.
Explain10 min, from minute 10
Lesson 3: Common denominators
Rewrite two fractions with the same denominator, then compare.
Worked example15 min, from minute 20
Lesson 4: Ordering sets
Put three or four fractions in order from smallest to largest.
Practice15 min, from minute 35
Lesson 5: Review
Mixed comparing questions, with feedback on each.
Review10 min, from minute 50
End-of-module test
Compare fractions with the same numerator or denominator, and order sets of fractions using a common denominator.
Mastered at 85% or more. Retake it until you pass; nothing is lost, and each try gives feedback.
Already know it? A Challenge Test (planned) clears the whole module: 90% overall, no objective below 75%.

Alignment in review until a qualified teacher or lecturer checks it. No exam body, university or vendor endorses us; learners still sit the real exam.
Challenge Test
Planned: a Challenge Test to prove you know it and skip it. Pass at 90% overall, with no objective below 75%.
The route here.
Everything this module builds on, drawn as a route from its foundations. Solid lanes must be mastered first, or cleared by a Challenge Test; dashed lanes are suggestions that never lock anything.
