Reporting Category 3 (TEKS 3.6 Two-Dimensional Figures)

Updated: Feb 13

Geometry and Measurement

The videos in this post explain mathematics Texas Essential Knowledge and Skill 3.6:

Geometry and measurement. The student applies mathematical process standards to analyze attributes of two-dimensional geometric figures to develop generalizations about their properties.

The STAAR videos below are selected released items from 3rd grade STAAR tests in 2016, 2018, 2019, and 2021. You can view the complete review of the 2017 STAAR test here.

 

3.6A

classify and sort two- and three-dimensional figures, including cones, cylinders, spheres, triangular and rectangular prisms, and cubes, based on attributes using formal geometric language

3.6B

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

3.6C

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

3.6D

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

3.6E

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
