Standard 1: The student measures quantities in the real world and uses the measures to solve problems.
Standard 2: The student compares, contrasts, and converts within systems of measurement (both standard/nonstandard and metric/customary).
Standard 3: The student estimates measurements in real-world problem situations.
Standard 4: The student selects and uses appropriate units and instruments for measurement to achieve the degree of precision and accuracy required in real-world situations.
Standard 1: The student measures quantities in the real world and uses the measures to solve problems.
Grades PreK - 2
- uses and describes basic measurement concepts including length,
weight, digital and analog
time, temperature, and capacity.
- uses standard customary and metric (centimeter, inch) and nonstandard units, such as links or blocks, in measuring real quantities.
Grades 3 - 5
- uses concrete and graphic models to develop procedures for solving
problems related to
measurement including length, weight, time, temperature, perimeter,
area, volume, and angle.
- solves real-world problems involving length, weight, perimeter, area, capacity, volume, time, temperature, and angles.
Grades 6 - 8
- uses concrete and graphic models to derive formulas for finding
perimeter, area, surface area,
circumference, and volume of two- and three-dimensional shapes,
including rectangular solids
and cylinders.
- uses concrete and graphic models to derive formulas for finding
rates, distance, time, and
angle measures.
- understands and describes how the change of a figure in such
dimensions as length, width,
height, or radius affects its other measurements such as perimeter,
area, surface area, and
volume.
- constructs, interprets, and uses scale drawings such as those based on number lines and maps to solve real-world problems.
Standard 2: The student compares, contrasts, and converts within systems of measurement (both standard/nonstandard and metric/customary).
Grades PreK - 2
- uses direct (measured) and indirect (not measured) comparisons to
order objects according
to some measurable characteristics (length, weight).
- understands the need for a uniform unit of measure to communicate in real-world situations.
Grades 3 - 5
- uses direct (measured) and indirect (not measured) measures to
calculate and compare
measurable characteristics.
- selects and uses appropriate standard and nonstandard units of measurement, according to type and size.
Grades 6 - 8
- uses direct (measured) and indirect (not measured) measures to
compare a given
characteristic in either metric or customary units.
- solves problems involving units of measure and converts answers to a larger or smaller unit within either the metric or customary system.
Standard 3: The student estimates measurements in real-world problem situations.
Grades PreK - 2
- using a variety of strategies, estimates lengths, widths, time intervals, and money and compares them to actual measurements.
Grades 3 - 5
- solves real-world problems involving estimates of measurements, including length, time, weight, temperature, money, perimeter, area, and volume.
Grades 6 - 8
- solves real-world and mathematical problems involving estimates of measurements including length, time, weight/mass, temperature, money, perimeter, area, and volume, in either customary or metric units.
Standard 4: The student selects and uses appropriate units and instruments for measurement to achieve the degree of precision and accuracy required in real-world situations.
Grades PreK - 2
- selects and uses an object to serve as a unit of measure, such as a
paper clip, eraser, or
marble.
- selects and uses appropriate instruments, such as scales, rulers, clocks, and technology to measure within customary or metric systems .
Grades 3 - 5
- determines which units of measurement, such as seconds, square
inches, dollars per tankful,
to use with answers to real-world problems.
- selects and uses appropriate instruments and technology, including scales, rulers, thermometers, measuring cups, protractors, and gauges, to measure in real-world situations.
Grades 6 - 8
- selects appropriate units of measurement and determines and applies
significant digits in a
real-world context. (Significant digits should relate to both
instrument precision and to the
least precise unit of measurement.)
- selects and uses appropriate instruments, technology, and techniques to measure quantities in order to achieve specified degrees of accuracy in a problem situation.
