Third Grade Geometry and Measurement

  • (6) The student applies mathematical process standards to analyze attributes of two-dimensional geometric figures to develop generalizations about their properties.


    The student is expected to:

          (A) classify and sort two- and three-dimensional solids, including cones, cylinders, spheres, triangular and       rectangular prisms, and cubes, based on attributes using formal geometric language;

          (B) use attributes to recognize rhombuses, parallelograms, trapezoids, rectangles, and squares as examples       of quadrilaterals and draw examples of quadrilaterals that do not belong to any of these subcategories;

          (C) determine the area of rectangles with whole number side lengths in problems using multiplication       related to the number of rows times the number of unit squares in each row;

          (D) decompose composite figures formed by rectangles into non-overlapping rectangles to determine the area of the original figure using the additive property of area; and

          (E) decompose two congruent two-dimensional figures into parts with equal areas and express the area of each part as a unit fraction of the whole and recognize that equal shares of identical wholes need not       have the same shape.


    (7) The student applies mathematical process standards to select appropriate units, strategies, and tools to solve problems involving customary and metric measurement.


    The student is expected to:

          (A) represent fractions of halves, fourths, and eighths as distances from zero on a number line;

          (B) determine the perimeter of a polygon or a missing length when given perimeter and remaining side lengths in problems;

          (C) determine the solutions to problems involving addition and subtraction of time intervals in minutes using pictorial models or tools such as a 15-minute event plus a 30-minute event equals 45 minutes;

          (D) determine when it is appropriate to use measurements of liquid volume (capacity) or weight; and

          (E) determine liquid volume (capacity) or weight using appropriate units and tools.
