Parts of a whole
Name and make fractions of a whole split into equal parts.
A sample lesson from this module is playable in the demo. The full module is not written yet; it is not a finished course.
Why it matters
Sharing a loaf or a paw-paw fairly means cutting equal parts; fractions are the names for those parts.

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: Equal parts
Fold paper and cut shapes to see that a fraction needs equal parts.
Explain15 min, from minute 0
Lesson 2: Top and bottom numbers
The bottom number says how many equal parts; the top says how many we have.
Explain15 min, from minute 15
Lesson 3: Fractions of groups
Find a half or a quarter of a group of beans or bottle tops.
Practice15 min, from minute 30
Lesson 4: Same amount, different names
Fold a strip to see that 2/4 covers the same amount as 1/2.
Investigate10 min, from minute 45
Lesson 5: Review
Mixed fraction questions, with feedback on each.
Review5 min, from minute 55
End-of-module test
Name and make fractions of shapes and groups, explain the top and bottom numbers, and spot when parts are not equal.
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%.

One question from the module, as a learner would meet it. Have a go, then open the worked solution a step at a time.

Aisha cuts a loaf into 5 equal slices and eats 2 of them. What fraction of the loaf did she eat, and what does each number mean?
Work it out on paper first, then show the answer and mark it yourself.

What a learner can do after it
- Say what the top and bottom numbers of a fraction mean.
- Make and name a fraction of a whole or a group split into equal parts.
- Know that fractions need equal parts, and spot simple fractions that name the same amount.
Needs first
This module has no prerequisites of its own. Like every first step, it assumes the Digital skills gateway: the first module on using a computer, which a Challenge Test clears in minutes.
