Multiplication as equal groups
Count equal groups quickly, and write them as a multiplication.
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
Eggs come in trays and yams are tied in bundles: when every group holds the same number, multiplication counts the lot in one go instead of one by one.

Inside the module.
4 lessons in order, about 45 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 groups
Spot groups that hold the same number, and groups that do not.
Explain10 min, from minute 0
Lesson 2: Repeated adding
Write 4 groups of 3 as 3 + 3 + 3 + 3, and then as 4 × 3.
Worked example10 min, from minute 10
Lesson 3: Pictures and stories
Match multiplications to pictures of baskets, rows of seedlings and bundles.
Practice15 min, from minute 20
Lesson 4: Review
Mixed questions on equal groups, with feedback on each.
Review10 min, from minute 35
End-of-module test
Write equal groups as multiplications, explain them as repeated adding, and choose the multiplication that fits a picture or story.
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%.
