Measurement, Classroom Case Studies Grade K-2: The Annenberg Foundation (website) - In 1st grade, students are not learning about measurement using standard units. They are simply comparing objects (e.g., how heavy or light something is; which object is heavier or lighter than others). Students measure length, mass, capacity and volume with uniform non-standard units such as clothespins, paper clips, pennies, centimeter cubes, or unifix cubes. In 3rd grade, the metric system is introduced as the standard science measurement system.
