Essential Content for Elementary Teachers
I. Know and understand the measurable attributes of objects (time, temperature, length, perimeter, area, volume, capacity, weight, and angle measure)
II. Know and understand the units of measurement, customary and metric systems of measurement, and the measuring process; understand aspects of size, be able to compare units and select the appropriate unit for the attribute being measured, and understand that measurements are approximations
III. Know how to use non-standard, customary, and metric units of measurement and be able to convert and operate within each system
IV. Develop formulas for measuring area, surface area and volume for two- and three-dimensional geometric shapes and explore the independence of perimeter and area, and surface area and volume
V. Use strategies for estimating (using referents, chunking, unitizing) linear measurement, area, and volume, and verify those estimates by use of non-standard and standard units
VI. Understand and use appropriate measurement instruments (rulers, scales, thermometers, clocks, calendars, beakers, cups, etc.)
VII. Know and understand the development of measurement in an historical context
