Fixed mindset: "I'm bad at maths" (permanent, unchangeable)
Growth mindset: "I'm not good at maths yet" (temporary, can improve)
Fixed mindset: "I failed because I'm not smart"
Growth mindset: "I failed because I didn't understand this concept. I need to try a different approach."
Growth mindset doesn't mean every kid can do everything. It means ability grows with effort and learning. That's true.
