Cactus Ranch Elementary School When you walk into Mr. Hinkle’s 5th grade class today, you will find a giant coordinate graph on the floor. Their challenge? Students have to practice plotting points on the graph by BEING the points! “We had to plot lots of points on our giant grid. I thought I was a certain point on the graph, but then my friend came to stand in my spot. We worked it out, and now we’re better at plotting points,” said one student!
