(Online MCA, 10–13 items) (Paper MCA, 10–13 items) 

Standard 3.3.1: Use geometric attributes to describe and create shapes in various contexts. 

(Online MCA, 3–4 items) (Paper MCA, 3–4 items)

Benchmarks Identify parallel and perpendicular lines in various contexts, and use them to describe and create geometric shapes, such as right triangles, rectangles, parallelograms and trapezoids. Item Specifications • When identifying shapes by the attribute of parallel or perpendicular lines, shapes are limited to triangle, parallelogram, rectangle, rhombus, square and trapezoid • Allowable notation: right angle symbol (square in corner) • Items will not require students to identify right triangles by name • Vocabulary allowed in items: parallel, perpendicular, right, figure Sketch polygons with a given number of sides or vertices (corners), such as pentagons, hexagons and octagons. Item Specifications • Allowable shapes: triangle, parallelogram, rectangle, rhombus, square, trapezoid, pentagon, hexagon, octagon • Vocabulary allowed in items: sides, angles, vertices, figure Standard 

3.3.2: Understand perimeter as a measurable attribute of real-world and mathematical objects. Use various tools to measure distances. 

(Online MCA, 3–4 items) (Paper MCA, 3–4 items) 

Benchmarks Use half units when measuring distances. Item Specifications • Not assessed on the MCA-III Find the perimeter of a polygon by adding the lengths of the sides. Item Specifications • Polygons may have 6 sides, at most • Items may require finding the length of an unknown side given the lengths of the other sides and the perimeter • Units are limited to inches, feet, yards, centimeters and meters • Vocabulary allowed in items: perimeter, length, width, side, figure 18 rade 3 Measure distances around objects. Item Specifications • Items may require identification of appropriate tools or procedures for measuring distance • Vocabulary allowed in items: tool, ruler, yardstick, meter stick, tape measure Standard 

3.3.3: Use time, money and temperature to solve real-world and mathematical problems. 

(Online MCA, 4–6 items) (Paper MCA, 4–5 items Tell time to the minute using digital and analog clocks. Determine elapsed time to the minute. Item Specifications • Elapsed time must be within a two-hour span • Vocabulary allowed in items: a.m., p.m. Know relationships among units of time. Item Specifications • Allowable conversions: minutes to hours, hours to minutes, hours to days, days to hours, days to weeks, weeks to days, months to years, years to months • Items may require finding a conversion with mixed units in the answer (e.g., 12 days = 1 week and 5 days) • Vocabulary allowed in items: unit Make change up to 1 dollar in several different ways, including with as few coins as possible. Item Specifications • Allowable coins: penny, nickel, dime, quarter • Allowable notation: $5, $0.75, 75¢ • When calculating change, the amount tendered is $10, at most • Vocabulary allowed in items: greatest, least, fewest, most, value Use an analog thermometer to determine temperature to the nearest degree in Fahrenheit and Celsius. Item Specifications • Allowable notation: 15ºF, 37ºC • Temperatures must be given in whole numbers • Vocabulary allowed in items: thermometer, temperature, degrees, increase, decrease
