Inside the module.
4 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: Unit fractions by sharing
Find 1/3 of 12 by sharing 12 things into 3 equal groups.
Explain15 min, from minute 0
Lesson 2: Divide by the bottom number
See that finding 1/5 of an amount means dividing it by 5.
Worked example15 min, from minute 15
Lesson 3: More than one part
Find 3/4 of 20 by finding 1/4 first, then taking 3 of them.
Worked example15 min, from minute 30
Lesson 4: Market and farm problems
Solve short stories about harvests, eggs and money.
Practice15 min, from minute 45
End-of-module test
Find unit and non-unit fractions of amounts, including in short story problems.
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%.
