Critical thinking is when you use your big kid brain to really think about something and figure out if it makes sense or not. It's like playing detective and asking lots of questions to get the truth.
In the movie about critical thinking, a group of kids from a disadvantaged neighborhood use their brains to win a fancy chess competition. They have to think really hard about their moves and figure out how to beat their opponents. But critical thinking is not just about chess; it's about using your brain to question things in your life.
For example, when you are watching a TV show or playing a game, you should ask yourself: "Does this make sense?" "Is it fair?" "Is it right?" These are important questions to ask because it's easy to get fooled or tricked sometimes. When you use critical thinking, you make sure that you understand the situation and the people around you.
So, critical thinking is like being a smart detective who asks lots of questions and thinks really hard to get the truth. It's important because it helps you make good decisions and understand the world around you.
