Thinking is what your mind does when it works with ideas, solves problems, remembers things, or imagines possibilities. Right now, as you read this sentence, you're thinking about what the words mean. When you wonder what's for dinner, figure out a math problem, or daydream about summer vacation, you're thinking.

Thinking takes many forms. Sometimes it's focused and deliberate, like when you concentrate on a chess move or plan how to build a treehouse. Other times it's quick and automatic, like when you instantly know that 5 plus 5 equals 10. You can think about concrete things you can see and touch, or abstract ideas like fairness or friendship.

People often use phrases that show different types of thinking. Critical thinking means carefully examining ideas rather than just accepting them. Creative thinking involves imagining new possibilities. When someone says “I'm thinking it over,” they mean they need time to consider something carefully before deciding.

The ability to think helps humans do many special things. We can think about the past, plan for the future, wonder about things we've never seen, and even think about thinking itself (which is exactly what you're doing right now). Scientists call this metacognition, which means thinking about your own thinking. Strong thinking skills develop through practice, curiosity, and asking good questions.
