Before You Read

a. What are critical thinking skills?

Critical thinking skills are the abilities that help a person analyze, evaluate, and reason logically about information before making a decision or forming an opinion. They involve thinking clearly, objectively, and creatively, rather than just accepting ideas at face value.

Some examples of critical thinking skills:

  • Analysis: Breaking information into parts to understand it better.

  • Evaluation: Judging the credibility and relevance of information.

  • Inference: Drawing logical conclusions from evidence.

  • Problem-solving: Finding effective solutions to challenges.

  • Self-reflection: Recognizing your own biases and assumptions.

In short, critical thinking is thinking smart and carefully instead of automatically or emotionally.


b. How do critical thinkers solve problems? Guess the steps they follow while tackling a problem.

Critical thinkers usually follow certain steps when tackling a problem. You can think of it like a step-by-step method:

  1. Identify the problem – Clearly understand what the problem is.

  2. Gather information – Collect all relevant facts, data, and opinions.

  3. Analyze the information – Look at the evidence carefully and identify patterns or issues.

  4. Consider alternatives – Think about different ways to solve the problem.

  5. Evaluate alternatives – Weigh the pros and cons of each solution.

  6. Make a decision – Choose the most logical and effective solution.

  7. Implement the solution – Put the chosen solution into action.

  8. Reflect and review – Check if it worked and learn from the process.

💡 Tip: Critical thinkers are also open-minded—they don’t get stuck on one idea and are willing to change their approach if new evidence appears.




Read the following text and do the given tasks.

There was a lot of shuffling around when the bell rang and everybody got up to leave. I checked my schedule and it said my next class was English, room 321. I didn’t stop to see if anyone else from my homeroom was going my way: I just zoomed out of the class and down the hall and sat down as far from the front as possible. The teacher, a really tall man with a yellow beard, was writing on the chalkboard.

Kids came in laughing and talking in little groups but I didn’t look up. Basically, the same thing that happened in homeroom happened again: no one sat next to me except for Jack, who was joking around with some kids who weren’t in our homeroom. I could tell Jack was the kind of kid other kids like. He had a lot of friends. He made people laugh.

When the second bell rang, everyone got quiet and the teacher turned around and faced us. He said his name was Mr. Browne, and then he started talking about what we would be doing this semester. At a certain point, somewhere between A Wrinkle in Time and Shen of the Sea, he noticed me but kept right on talking.

I was mostly doodling in my notebook while he talked, but every once in a while I would sneak a look at the other students. Charlotte was in this class. So were Julian and Henry. Miles wasn’t.

Mr. Browne had written on the chalkboard in big block letters:


P-R-E-C-E-P-T!

“Okay, everybody write this down at the very top of the very first page in your English notebook.” As we did what he told us to do, he said: “Okay, so who can tell me what a precept is? Does anyone

know?”

No one raised their hands. Mr. Browne smiled, nodded, and turned around to write on the chalkboard again:

PRECEPTS = RULES ABOUT REALLY IMPORTANT THINGS!

“Like a motto?” someone called out.

“Like a motto!” said Mr. Browne, nodding as he continued writing on the board. “Like a famous quote. Like a line from a fortune cookie. Any saying or ground rule that can motivate you. Basically, a precept is anything that helps guide us when making decisions about really important things.”

He wrote all that on the chalkboard and then turned around and faced us. “So, what are some really important things?” he asked us.

A few kids raised their hands, and as he pointed at them, they gave their answers, which he wrote on the chalkboard in really, really sloppy handwriting:

RULES. SCHOOLWORK. HOMEWORK.

“What else?” he said as he wrote, not even turning around. “Just call things out!” He wrote everything everyone called out.

FAMILY. PARENTS. PETS.

One girl called out: “The environment!”

THE ENVIRONMENT.

He wrote on the chalkboard, and added:

OUR WORLD!

“Sharks, because they eat dead things in the ocean!” said one of the boys, a kid named

Reid, and Mr. Browne wrote down SHARKS.

Bees!” “Seatbelts!” “Recycling!” “Friends!”

“Okay,” said Mr. Browne, writing all those things down. He turned around when he finished writing to face us again. “But no one’s named the most important thing of all.” We all looked at him, out of ideas.

“God?” said one kid, and I could tell that even though Mr. Browne wrote “God” down, that wasn’t the answer he was looking for. Without saying anything else, he wrote down:

WHO WE ARE!

“Who we are,” he said, underlining each word as he said it. “Who we are! Us! Right? What kind of people are we? What kind of person are you? Isn’t that the most important thing of all? Isn’t that the kind of question we should be asking ourselves all the time? “What kind of person am I?

“Did anyone happen to notice the plaque next to the door of this school? Anyone read what it says? Anyone?”

He looked around but no one knew the answer.

“It says: ‘Know Thyself,’ ” he said, smiling and nodding. “And learning who you are is what you’re here to do.”

“I thought we were here to learn English,” Jack cracked, which made everyone laugh. “Oh yeah, and that, too!” Mr. Browne answered, which I thought was very cool of him. He turned around and wrote in big huge block letters that spread all the way across the chalkboard:

MR. BROWNE’S SEPTEMBER PRECEPT: WHEN GIVEN THE CHOICE BETWEEN BEING RIGHT OR BEING KIND, CHOOSE KIND.

“Okay, so, everybody,” he said, facing us again, “I want you to start a brand-new

section in your notebooks and call it Mr. Browne’s Precepts.” He kept talking as we did what he was telling us to do.

“Put today’s date at the top of the first page. And from now on, at the beginning of every month, I’m going to write a new Mr. Browne precept on the chalkboard and you’re going to write it down in your notebook. Then we’re going to discuss that precept and what it means. And at the end of the month, you’re going to write an essay about it, about what it means to you. So by the end of the year, you’ll all have your own list of precepts to take away with you.

“Over the summer, I ask all my students to come up with their very own personal precept, write it on a postcard, and mail it to me from wherever you go on your summer vacation.” “People really do that?” said one girl whose name I didn’t know.

“Oh yeah!” he answered, “people really do that. I’ve had students send me new precepts years after they’ve graduated from this school, actually. It’s pretty amazing.” He paused and stroked his beard.

“But, anyway, next summer seems like a long way off, I know,” he joked, which made us laugh. “So, everybody relax a bit while I take attendance, and then when we’re finished with that, I’ll start telling you about all the fun stuff we’re going to be doing this year—in English.” He pointed to Jack when he said this, which was also funny, so we all laughed at that.

As I wrote down Mr. Browne’s September precept, I suddenly realized that I was going to like school. No matter what.

 Critical thinking

a. Have you made your own precept after you read this lesson? What is it? Share it with your friends.
Yes, I have made my own precept after reading this lesson.
My precept is: “Always be honest, even when it is difficult.”
This precept reminds me to act truthfully and responsibly in every situation and to treat others with fairness and respect.

b. According to Josh Lanyon, “If there was one life skill everyone on the planet needed, it was the ability to think with critical objectivity.” Justify this statement with your logic.
The statement is true because critical objectivity helps people think clearly and make fair decisions. When we think objectively, we do not let emotions, personal bias, or pressure influence our judgment. This skill helps us understand situations better, solve problems wisely, and respect different opinions. In today’s world, where misinformation is common, critical thinking allows people to judge what is right or wrong and make responsible choices in life.


 

Writing


Write an email to your friend explaining an interesting class you had.

Dear Friend,

I hope you are doing well. I want to tell you about an interesting class I had today at school.

It was our English class, and the teacher, Mr. Browne, spoke about something called a “precept.” He explained that a precept is a rule or saying that helps guide us in life. He asked us what the most important thing in the world is, and finally told us that it is “who we are.” His precept for the month was, “When given the choice between being right or being kind, choose kind.”

The class was very engaging, and everyone participated actively. It made me think deeply about my own behavior and choices. I really enjoyed the lesson and felt inspired by it.

Do write back and tell me about your classes.

Take care.

Best wishes,
Your friend
