Effective method

Okay kiddo, so an effective method is basically a way of doing something that works really well. It's like if you want to build a tower out of blocks - you might try just stacking them up randomly, but that might not work very well and it might fall over. But if you start by putting the biggest blocks on the bottom and then working your way up to the smaller ones, that's an effective method because it's more likely to make a strong tower that won't fall over.

Another example might be if you want to learn how to play the piano. You could just try randomly hitting the keys, but that's not going to get you very far. But if you follow a structured method, like starting with easy songs and practicing your scales every day, then that's an effective method because it will help you improve faster and become a better piano player.

So basically, an effective method is just a way of doing something that makes it more likely for you to succeed and do well. It's like having a map or a plan that can help you reach your goals.
