Fractions on a number line
See fractions as numbers with their own place between whole numbers.
Planned. This module is part of the plan and is not written yet.
Why it matters
A ruler, a fuel gauge and the marks on a measuring jug all show fractions as points on a line: half full is a place, not just a piece.

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: From pieces to points
Split the line from 0 to 1 into equal jumps and label 1/4, 2/4 and 3/4.
Explain15 min, from minute 0
Lesson 2: Placing fractions
Mark halves, thirds, quarters and fifths on number lines.
Practice15 min, from minute 15
Lesson 3: Counting past one
Count on in thirds: 1/3, 2/3, 3/3 = 1, 4/3, 5/3.
Worked example15 min, from minute 30
Lesson 4: Measuring with fractions
Fold a paper strip into quarters and use it to measure things in the room.
Investigate10 min, from minute 45
Lesson 5: Review
Mixed number-line questions, with feedback on each.
Review5 min, from minute 55
End-of-module test
Place fractions between 0 and 1 on a number line, and count on in fractions past one whole.
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%.
