One-step equations
Solve equations like x + 7 = 12 and 4x = 20 by doing the same to both sides.
Planned. This module is part of the plan and is not written yet.
Why it matters
If Musa needs ₦700 more to reach the ₦2,500 for a school bag, the equation x + 700 = 2,500 tells him how much he has already saved.

Inside the module.
5 lessons in order, about 75 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 to both sides
Keep the balance level by doing the same thing to both sides.
Explain15 min, from minute 0
Lesson 2: Adding and subtracting
Solve x + 7 = 12 and x − 3 = 9 by undoing the operation.
Worked example15 min, from minute 15
Lesson 3: Multiplying and dividing
Solve 4x = 20 and x ÷ 5 = 3 by undoing the operation.
Worked example15 min, from minute 30
Lesson 4: Mixed practice
Choose the right inverse for each equation, and check by substitution.
Practice20 min, from minute 45
Lesson 5: Review
Mixed questions, with feedback on each.
Review10 min, from minute 65
End-of-module test
Solve one-step equations with each of the four operations, and check every answer by substitution.
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%.

Practicalities

Planned to run on the Lantern's own computer, with no internet needed.
Languages
Planned first in English; every module aims to reach all of the Lantern's languages.
Try a question.
One question from the module, as a learner would meet it. Have a go, then open the worked solution a step at a time.

Solve x ÷ 6 = 7.
Work it out on paper first, then show the answer and mark it yourself.
