A ruler make me think of many things. it makes me think of sports because in track when you do long jump or triple jump they have to see how long your jump was. It also makes me think of numbers because it has numbers on it. Also houses, floors, walls, or landscaping. All people dealing with construction need to know how to use or measure with a ruler. Also carpenters do to or people who draw or construct buildings so they can know how long or wide a wall, window, or floor needs to be.
