Content Strand 2: Measurement - Item Specification (8-2005)

ME03 (Procedures): Use systematic procedures to measure, describe, and compare angle measurements or the volumes of rectangular prisms - identify the attribute to be measured, select and use appropriate unit of measurement, select and use a tool that matches the unit chosen, compare attribute to units on tool or count to determine the number of units; use formulas to determine missing measurements for circles, triangles, and rectangular prisms (1.2.4, 1.2.5)

Item Format:

· Multiple-Choice and Short-Answer items may be used to test this learning target.

Stimulus, Stem, and Prompt Rules:

· Stimulus may include pictures, tables, charts, diagrams, figures, illustrations, and written descriptions.
· Stimulus may include formulas for circumference or area of a circle.
· The answer and distracters will be stated in terms of the same system of measurement.
· Items will not require students to convert from U.S. to metric or metric to U.S.
· Conversion facts may be given in an item, e.g., 1 mile = 5,280 feet.
· Stimulus may include illustrations of tools that are familiar to seventh-grade students.

Mathematical Vocabulary and Terms:

· Terms that may be used: angle, area, centimeter, cubic unit, degree, foot/feet, inch, kiloliter, kilometer, length, meter, mile, millimeter, perimeter, square unit, unit, volume, width, yard
· Terms that may be used with definitions or examples: compare (tell how they are alike and/or how they are different), evaluate
· Terms that may not be used:
· Students are expected to know how to determine the following:

Perimeter of a polygon

Area of a rectangle Area of a triangle

Volume of a rectangular prism

Item Characteristics: a) Items may ask students to identify or describe appropriate units for measuring an angle.
b) Items may ask students to use and/or describe procedures for measuring length, perimeter, area, volume and/or angle measurement:

· identify the attribute to be measured;
· select and use an appropriate unit of measurement;
· select and use a tool that matches the unit chosen;
· compare the attribute to the units on the tool or count to determine the number of units.

c) Items may ask students to evaluate whether measurement has been done correctly.
d) Items may ask students to determine circumference, perimeter, and/or area of a circle, rectangle, and/or triangle.
e) Items may ask students to determine volume and/or surface area of a rectangular prism.
f) Items may ask students to determine linear dimensions of a circle, triangle, or rectangle based on a given circumference, perimeter, or area.
g) Items may ask students to determine linear dimensions of a rectangular prism based on a given volume or surface area.
h) Items may ask students to compare angle measurements or the volumes of rectangular prisms.
Note: Students are expected to determine and label units.
