Proving something is like showing your friend how your toy works. When you have a toy car, you can prove it moves by pushing it and letting your friend see it roll. Your friend needs to see the car actually move to believe you.
Another way to think about proving is like when you say you can build the tallest block tower. To prove it, you start stacking blocks one on top of another until your tower is really tall. Your friends can watch you build it and see for themselves that it’s the tallest.
Proving is also like when you say you can make a yummy sandwich. To prove it, you make the sandwich and let your friend taste it. When they taste how good it is, they know you were telling the truth.
So, proving is about showing or doing something that helps others understand and believe what you say. It’s like giving them a reason to say, ‘Oh, I see! You’re right!’ because they can see, touch, or taste it themselves.
