Students will be asked to list attributes of objects that they can measure, using a known measuring tool. For example, students should know they can measure and compare weights using a scale. They should also know they can measure and compare lengths using rulers. They should know you can measure and compare temperatures using thermometers. An attribute such as color might be measurable according to some computer vision application, but there's no consensus as to what range of hues is red, blue, etc. so we'll consider things like this to be non-measurable. An attribute such as softness is certainly measurable, that is, we could invent a machine that measures softness, according to some definition of softness, but that tool either doesn't exist currently, or is not readily available to the student, so we'll consider things like softness to be non-measurable as well. Students will also be given objects, and asked to list several attributes they can measure for each object. For example, a coffee mug has a weight and a height.
K.MD.A.1: Describe measurable attributes of objects, such as length or weight. Describe several measurable attributes of a single object.
