Project-Based Learning (PBL) in a math class makes learning math more interesting. Instead of just doing exercises, students work on real-life projects using math. They might plan a budget, analyze data, or design things like buildings using math concepts. PBL helps students learn math better by letting them use it in practical ways. It also teaches them to work together, solve problems, and think creatively. This way of learning helps students see how math is useful in real life and prepares them for jobs where they'll need these skills.
