In maths we were told to make a poster or a movie of some sort and then we would prove it to a teacher or adult. What a prove it is, is a thing where you make something to show that you know how to do it. There is a graph that the teacher signs so you can manage the prove it. There is only one type of signature on the prove it box on my graph. But you do not actually have to have the same teacher that you prove it to. Here is a picture of the prove it that I did.
