Measurement

Measurement Standard Through the measurement standard students learn to estimate and measure to a required degree of accuracy and precision by selecting and using appropriate units, tools and technologies.

By the end of the K-2 program students should be able to...
 * Explain the need for standard units of measure.
 * Select appropriate units for length, weight, volume, and time, using...
 * objects
 * U.S. customary units: inch, foot, yard, ounce, pound, cup, quart, gallon, minute, hour, day, week and year
 * metric units: centimeter, meter, gram and liter.
 * Develop references for units of measure of length, weight, volume and time to make comparisons and estimates.
 * Apply measurement techniques to measure length, weight and volume.
 * Recognize that using different units of measurement will give them different numbers for the same measurement.

By the end of the 3-4 program students should be able to...
 * Select appropriate units for length, weight, volume, and time, using...
 * objects
 * U.S. customary units: mile, square inch, cubic inch, second, degree Fahrenheit.
 * metric units: milimeter, kilometer, square centimeter, kilogram, cubic centimeter, degree Celsius.
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">Know that the number of units is inversely related to the size of the unit for any item being measured.
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 14px; line-height: 21px;">Develop references for units of measure of length, weight, volume and time to make comparisons and estimates.
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 14px; line-height: 21px;">Identify appropriate tools and apply counting techniques for measuring side lengths, perimeter and area of squares, rectangles, and simple irregular two-dimensional shapes, volume of rectangular prisms, and time and temperature.
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">Tell time to the nearest minute.

<span style="color: #4682d2; font-family: 'Times New Roman',Times,serif; font-size: 110%;">By the end of the 5-7 program students should be able to...
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">Select appropriate units to measure angles, circumference, surface area, mass and volume, using:
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">U.S. customary units: degrees, square feet, pounds.
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">metric units: square meters, kilograms.
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">Convert units of length, area, volume, mass and time within the same measurement system.
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">Identify appropriate tools and apply appropriate techniques for measuring angles, perimeter or circumference and area of triangles, quadrilaterals, circles and composite shapes, and surface area and volume of prisms and cylinders.
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">Select a tool and measure accurately to a specified level of precision.
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">Use problem solving techniques and technology as needed to solve problems involving length, weight, perimeter, area, volume, time and temperature.
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">Analyze and explain what happens to area and perimeter or surface area and volume when the dimensions of an object are changed.
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">Understand and demonstrate the difference of perimeter and area for two-dimensional shapes and of surface area and volume for three-dimensional shapes.

<span style="color: #4682d2; font-family: 'Times New Roman',Times,serif; font-size: 110%;">By the end of the 8-10 program students should be able to...
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">Solve increasingly complex non-routine measurement problems and check for reasonableness of results.
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">Use formulas to find surface area and volume for specified three-dimensional objects accurate to a specified level of precision.
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">Apply indirect measurement techniques, tools and formulas, as appropriate, to find perimeter, circumference and area of circles, triangles, quadrilaterals and composite shapes, and to find volume of prisms, cylinders, and pyramids.
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">Use proportional reasoning and apply indirect measurement techniques, including right triangle trigonometry and properties of similar triangles, to solve problems involving measurements and rates.
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">Estimate and compute various attributes, including length, angle measure, area, surface area and volume, to a specified level of precision.
 * <span style="font-family: 'Times New Roman',Times,serif; font-size: 110%;">Write and solve real-world, multi-step problems involving money, elapsed time and temperature, and verify reasonableness of solutions.
