5 Lesson 3: Making Better Decisions in English
Duration: 2 hours
TipYour Path
You are in: Lesson 3
Before this: Lesson 2
After this: Lesson 4
Workbook page: Student Workbook -> Lesson 3 - English Decision Matrix
5.1 Start Here
You make decisions every day. Which class to take. Which job to apply for. How to spend time and money. AI can help you see options and compare them in English. But AI does not know your life. You do. Today you will learn a simple decision matrix and a human final decision rule.
5.2 Why This Matters
Decisions will determine your future. Making a careful decision can lead to better outcomes. AI can help you see the full picture, but you must check the details and make the final choice. This skill will help you in school, work, and life.
TipWrite in the Book
Some exercises in the website version are interactive. You can type your answers directly on the page, and you can copy or download a backup if your teacher asks.
The main task is to write in the book, not to create separate files.
5.3 Decision Poll: Are We Really in Control?
5.4 Today You Will
By the end of this lesson, you will:
- Learn what a matrix is and the parts of a decision matrix.
- Use a CLEAR prompt template for a decision matrix.
- Compare options using criteria, weights, risks, and evidence.
- Write a final decision and explain your reason.
- Explain why AI should not make the final decision.
- Complete the matching Student Workbook page.

I might choose...
I chose this because...
The risk is...5.5 Core Idea
A matrix is a table with a job. It organizes ideas in rows and columns.
A decision matrix is a matrix for comparing choices. You pick the things that matter to you, called criteria. You add options, weights, scores, and short evidence notes.
AI can help organize the matrix quickly. It can suggest criteria, scores, assumptions, and risks. But AI does not know your whole life. You must check the draft matrix, verify important facts, adjust weak parts, and make the final decision.
ImportantHuman Final Decision Rule
AI can help you compare. You make the final decision.
NoteMethod Note
This activity adapts the decision matrix, also called a Pugh matrix, decision grid, or selection matrix. A decision matrix helps compare options against criteria and can use weights when some criteria matter more (American Society for Quality n.d.).

5.9 First: What Is a Matrix?
A matrix is a table with a job. It organizes ideas in rows and columns so we can compare, sort, or decide. A normal table stores information, but a matrix helps us use information to make better decisions. One useful example is the Eisenhower Matrix, which helps people sort tasks.
The Eisenhower Matrix helps people sort tasks by importance and urgency. We use it here as a simple example before we compare choices with a decision matrix.
Ask two questions:
- Is it important?
- Is it urgent?
| Task type | Urgent | Not urgent |
|---|---|---|
| Important | Do soon | Plan |
| Not important | Limit | Skip or save for later |
Try it as a class. Where does each task go?
| Task | Possible place |
|---|---|
| Homework due tomorrow | Important + urgent: Do soon |
| English practice for this week | Important + not urgent: Plan |
| Checking a small message | Not important + urgent: Limit |
| Choosing a phone wallpaper | Not important + not urgent: Skip or save for later |
This matrix helps us sort tasks. Next, a decision matrix will help us compare choices.
5.10 From Polls to a Decision Matrix
The poll showed that words, numbers, defaults, choices, ownership, loss, and people can influence decisions. A decision matrix helps us slow down and compare options more clearly.
Now try one bigger decision.
5.11 The Job Offer Problem
Maria receives two fictional job offers after graduating.
Her first reaction is obvious:
I should take Job Offer A. It pays $12,000 more per year.Before you see the full matrix, vote quickly:
Which offer looks better at first?
A. Offer A: $82,000 salary
B. Offer B: $70,000 salary
C. I am not sureAt first glance, Offer A looks better because $82,000 is more than $70,000. But salary is only one part of the decision.
5.11.1 The Job Offers
| Detail | Offer A: Higher salary, weaker fit | Offer B: Lower salary, stronger fit |
|---|---|---|
| Salary | $82,000 | $70,000 |
| Commute | 60 minutes each way | 15 minutes each way |
| Manager | Seems demanding and unclear | Supportive and clear |
| Growth | Limited training and unclear promotion path | Strong training program and mentorship |
| Benefits | Basic health insurance, little retirement match | Better health insurance, retirement match, paid professional development |
| Work-life balance | Often requires evenings | Stable schedule, hybrid flexibility |
5.12 Your Mission
Help Maria see the full picture, not only salary.
Your mission is to use a decision matrix and a CLEAR AI-assisted prompt to organize the decision. AI can help make the table, but Maria must check the result and make the final decision.
Salary can hide important questions:
- How much time will the commute take?
- Will the manager and team support learning?
- Is there training for future growth?
- Will the schedule be healthy and sustainable?
- What facts still need verification?
5.13 CLEAR AI-Assisted Matrix Prompt
5.13.1 Copy the Maria Job Offers Prompt
Use this complete prompt for the class example. It uses fictional job offers, so it is safe to copy into the school-provided AI tool.
CLEAR Maria job offers prompt
Context:
I am an English learner practicing decision-making.
I need help organizing a safe fictional job-offer decision into a decision matrix.
The decision is: Should Maria choose Offer A or Offer B?
Offer A: Higher salary, weaker fit
Salary: $82,000.
Commute: 60 minutes each way.
Manager: Seems demanding and unclear.
Growth: Limited training and unclear promotion path.
Benefits: Basic health insurance and little retirement match.
Work-life balance: Often requires evenings.
Offer B: Lower salary, stronger fit
Salary: $70,000.
Commute: 15 minutes each way.
Manager: Supportive and clear.
Growth: Strong training program and mentorship.
Benefits: Better health insurance, retirement match, and paid professional development.
Work-life balance: Stable schedule and hybrid flexibility.
Limits:
Use simple English.
Do not ask for private information.
Do not make the final decision for Maria.
Do not invent facts. Write "Needs verification" when information is missing.
Do not give medical, legal, immigration, financial, or emergency advice.
Treat scores as draft suggestions that Maria must check.
Example or output format:
Make a weighted decision matrix with these columns:
Criteria | Weight | Offer A Score | Offer A Weighted | Offer B Score | Offer B Weighted | Evidence / Notes
Use scores from 1 to 5, where 5 is best.
Use useful criteria such as salary / compensation, career growth, manager / team quality, work-life balance, and commute / flexibility.
After the table, list:
1. One assumption Maria should check.
2. One risk Maria might forget.
3. One fact Maria should verify.
Ask:
Organize Maria's job-offer decision into a decision matrix.
Review:
Before answering, check that this task is fictional, safe, simple, and does not include private information.
End with: "Maria makes the final decision."
5.13.2 Copy the Template for Your Own Safe Decision
Copy this template for independent practice. Replace the bracketed parts with safe fictional or everyday details. Use the school-provided AI tool if your teacher asks you to test it.
CLEAR decision matrix prompt template for your own decision
Context:
I am an English learner practicing decision-making.
I need help organizing a safe fictional or everyday decision into a decision matrix.
The decision is: [decision question].
The options are:
A. [option A]
B. [option B]
Important details I know:
[short safe facts only]
Limits:
Use simple English.
Do not ask for private information.
Do not make the final decision for me.
Do not invent facts. Write "Needs verification" when information is missing.
Do not give medical, legal, immigration, financial, or emergency advice.
Treat scores as draft suggestions that I must check.
Example or output format:
Make a table with:
Criteria | Weight | Option A Score | Option A Weighted | Option B Score | Option B Weighted | Evidence / Notes
Use scores from 1 to 5, where 5 is best.
After the table, list:
1. One assumption I should check.
2. One risk I might forget.
3. One fact I should verify.
End with: "You make the final decision."
Ask:
Organize this decision into a decision matrix.
Review:
Before answering, check that the task is safe, simple, and does not include private information.
5.14 Guided Practice
5.14.1 Compare Two Job Offers
Maria decides salary matters, but it should not be the only factor.
| Criterion | Weight | Why it matters |
|---|---|---|
| Salary / compensation | 30% | Income is important. |
| Career growth | 25% | Future opportunities matter. |
| Manager / team quality | 20% | Daily experience matters. |
| Work-life balance | 15% | Health and sustainability matter. |
| Commute / flexibility | 10% | Time, stress, and cost matter. |
Scores are from 1 to 5, where 5 is best.
| Criteria | Weight | Offer A Score | Offer A Weighted | Offer B Score | Offer B Weighted |
|---|---|---|---|---|---|
| Salary / compensation | 0.30 | 5 | 1.50 | 3 | 0.90 |
| Career growth | 0.25 | 2 | 0.50 | 5 | 1.25 |
| Manager / team quality | 0.20 | 2 | 0.40 | 5 | 1.00 |
| Work-life balance | 0.15 | 2 | 0.30 | 4 | 0.60 |
| Commute / flexibility | 0.10 | 1 | 0.10 | 5 | 0.50 |
| Total | 1.00 | 2.80 | 4.25 |
5.15 The Decision Reversal
The intuitive choice was:
Take Offer A because it pays more.The decision matrix suggests:
Offer B may be stronger overall.Offer A wins on salary. Offer B wins on career growth, manager quality, work-life balance, and commute. The matrix does not force the final decision, but it helps Maria see the full picture.
5.16 The Commute Twist
Offer A commute:
2 hours per day x 5 days = 10 hours per weekOffer B commute:
30 minutes per day x 5 days = 2.5 hours per weekDifference:
7.5 hours per week x 48 working weeks = 360 extra hours per yearThat is like losing nine full 40-hour workweeks every year just to commute.
Without the matrix, Maria focused only on salary. With the matrix, she can see long-term value, stress, growth, and daily life.
Big idea: the biggest number is not always the best value.
5.16.1 Practice the Comparison Sentences
Write three comparison sentences. Examples:
Offer A pays more than Offer B.
Offer B has a shorter commute than Offer A.
I might choose Offer B because growth and work-life balance are important.Job Offer Comparison Sentences
